PermaBASE

The Best Base for a Great Finish

PermaBASE Building Products, LLC offers the industry’s largest variety of cement boards covering the most demanding interior and exterior applications. Our mission is to continue to innovate new products and solutions to serve the industry.

The PermaBASE family of products provide performance and peace of mind with valuable features and applications that save the contractor time and money.

We innovated the use of lightweight polystyrene beads within our

Portland cement core to provide performance benefits unique to the PermaBASE family of products.

• The use of polystyrene aggregate makes PermaBASE products significantly lighter and easy to cut.

• The beads also contribute to the industry's lowest water absorption, preventing the adhering mortar from drying prematurely.

These products provide the industry’s best warranties with a lifetime limited interior warranty and 15-year limited exterior warranty.

We have the size you need, and the product quality you expect for all your applications.

(wood) or 20 gauge (metal).

For flooring applications with 16” o.c. floor joists, 5/8” tongueand-groove exterior-grade plywood or 3/4” tongue-and-groove exterior-grade OSB may be used. For 19.2” o.c. and 24” o.c. floor joists, 3/4” tongue-and-groove exterior-grade plywood or OSB must be used. Tile size for floors with 24” o.c. floor joists must be

12” x 12” or larger. The joist and subfloor assembly must meet

L/360 (L/720 for stone) as well as the appropriate code tables for live and dead loads. Install tile and tile setting materials in accordance with current ANSI specifications and Tile Council of

North America (TCNA) guidelines.

Control Joints: Consult TCNA Handbook Installation Method

EJ171. Architect, builder or design professional must specify location of all control joints. For interior installations, allow a maximum of 30 lineal feet between control joints. A control joint must be installed but not limited to the following locations: where expansion joints occur in the framing or building (discontinue all cross-furring members located behind joint); when boards abut dissimilar materials; where framing material changes; at changes of building shape or structural system; at each story separation.

Place control joints at corners of window and door openings, or follow specifications of architect. Control joint cavity shall not be filled with coating or other materials.

WALLS

Wall Framing: Edges of PermaBASE WP parallel to framing should be continuously supported. Provide additional blocking when necessary to permit proper attachment. Do not install

PermaBASE WP directly over protrusions from stud plane, such as heavy brackets and fastener heads. Studs above a shower floor should either be notched or furred to accommodate the thickness of the waterproof membrane or pan. The surround opening for a tub or precast shower receptor should not be more than 1/4” longer than unit to be installed. In mortar bed (mud bed) applications, PermaBASE Cement Boards can be embedded into the mud bed per TCNA Handbook method B415-19.

PermaBASE WP: Apply PermaBASE WP with ends and edges closely butted but not forced together. Stagger end joints in successive courses. Drive fasteners into field of board first, working toward ends and edges. Space fasteners maximum

8” o.c. for walls, with perimeter fasteners at least 1/2” and less than 3/4” from ends and edges. Ensure PermaBASE WP is tight to framing. Install screws flush with surface, do not overdrive screws.

Joint Reinforcement: Trowel bonding material to completely fill the board joints and gaps between each panel. Apply a 6” wide, approx. 1/16” thick coat of bonding material over entire joint.

For all joints, immediately embed 2” alkali-resistant fiberglass mesh tape fully into applied bonding material and allow it to cure. For outside corners, 4” wide alkali-resistant mesh tape is recommended. Same bonding material should be applied to corners, control joints, trims and other accessories. Feather bonding material over fasteners to fully conceal. Bonding material to be modified dry set mortar compliant with

ANSI A118.4 standards. In wet-area installations, apply approved fluid applied waterproofing per manufacturer’s recommendations over entire surface to receive tile.

Sealant/Waterproofing Application: In areas where waterproof performance is required, apply approved liquid waterproofing/ sealant over cement board joints and fastener heads/ penetrations, as well as any exposed edges. Waterproofing must extend past treated joint onto PermaBASE WP surface a minimum of 2” on either side of the joint. This includes inside and outside corners. Follow waterproofing manufacturer’s instructions on application requirements. Once all board joints have been treated following this procedure, seal all fasteners with approximately a

2” diameter coating of liquid waterproofing or approved sealant.

FLOORS AND COUNTERS

Subfloor or Base: For flooring applications with 16” o.c. floor joists, 5/8” tongue-and-groove exterior-grade plywood or 3/4” tongue-and -groove exterior-grade OSB may be used. For 19.2” o.c. and 24” o.c. floor joists, 3/4” tongue-and-groove exteriorgrade plywood or OSB must be used. Tile size for floors with 24” o.c. floor joists must be 12” x 12” or larger. The joist and subfloor assembly must meet L/360 as well as the appropriate code tables for live and dead loads.

Underlayment: Using a 1/4” square-notched trowel, apply a setting bed of polymer-modified mortar (or thin-set mortar) to the subfloor or counter base. Immediately laminate PermaBASE WP to subfloor or base with ends and edges closely butted but not forced together. Leave a 1/4” gap along walls. Stagger all joints so that they do not line up with underlying substrate joints. Fasten

PermaBASE WP every 8” o.c. throughout board field and around all edges while setting bed mortar is still workable. Around perimeter of each board, locate fasteners 2” from corners and not less than 3/8” from the edges. Fill all joints solid with bonding material. On non-tapered joints such as butt ends, apply a 6” wide,

1/16” thick coat over the entire joint. For all joints, immediately embed 2” alkali-resistant fiberglass mesh tape fully into applied bonding material; ensure that tape is centered over joint. Apply bonding material over fasteners to fully conceal. Remove all excess bonding material and allow to cure.

FLOORS AND COUNTERS

Subfloor or Base: For flooring applications with 16” o.c. floor joists, 5/8” tongue-and-groove exterior-grade plywood or 3/4” tongue-and-groove exterior-grade OSB may be used. For 19.2” o.c. and 24” o.c. floor joists, 3/4” tongue-and-groove exteriorgrade plywood or OSB must be used. Tile size for floors with 24” o.c. floor joists must be 12” x 12” or larger. The joist and subfloor assembly must meet L/360 as well as the appropriate code tables for live and dead loads.

Underlayment: Using a 1/4” square-notched trowel, apply a setting bed of polymer-modified mortar (or thin-set mortar) to the subfloor or counter base. Immediately laminate PermaBASE®

Cement Board to subfloor or base with ends and edges closely butted but not forced together. Leave a 1/4” gap along walls.

Stagger all joints so that they do not line up with underlying substrate joints. Fasten PermaBASE Cement Board every 8” o.c. throughout board field and around all edges while setting bed mortar is still workable. Around perimeter of each board, locate fasteners 2” from corners and not less than 3/8” from the edges.

Fill all joints solid with bonding material. On non-tapered joints such as butt ends, apply a 6” wide, 1/16” thick coat over the entire joint. For all joints, immediately embed 2” fiberglass mesh tape fully into applied bonding material; ensure that tape is centered over joint. Apply bonding material over fasteners to fully conceal.

Remove all excess bonding material and allow to cure.

LIMITATIONS

Wall Protector/Heat Shield

1/2” PermaBASE and 1/2” PermaBASE PLUS are listed by

Underwriters Laboratories, Inc., for use with UL-listed solid-fuel room heaters and fireplace stoves. Used as a wall protector/ heat shield, PermaBASE Cement Board reduces by 40 percent the manufacturer-specified clearance (minimum 12" [305 mm]) between the room heater or stove and a combustible wall surface.

Installation: Furring is made by cutting a full PermaBASE panel into 4" (102 mm) wide strips with a carbide-tipped saw or utility knife. Attach a double layer of furring strips to the wall studs using cement board screws, which provide a minimum penetration of 3/4” (19.1 mm) into the framing.

When installing panels, leave a 3" (76.2 mm) gap at the ceiling and 1” (25.4 mm) to 2” (50.8 mm) gap at the floor. This air space is required for the proper functioning of the heat shield. Do not close or block these openings.

Heat shield panels may be cut to required size using a standard utility knife or power saw. Fasten the PermaBASE panels to the studs with galvanized roofing nails or cement board screws spaced 8” (203 mm) o.c. Cement board screws must be long enough to penetrate into framing a minimum of 3/4” (19.1 mm).

Do not install any nails or screws into the wall area directly behind the proposed location of the appliance.

Finishing: Prefill joints with dry-set mortar, then immediately embed PermaBASE™ Cement Board Tape and level joints. As an alternative, apply PermaBASE Tape over the joints, then apply dry-set mortar, forcing it through the tape to completely fill and level the joints. All non-combustible finishes, such as ceramic tile, thin brick or stone, can be applied over wall-shield.

Do not apply combustible finishes, such as wallpaper, to cement board surface.

Note: Do not put screws in projected appliance area of the heat shield.

Exterior Installation of

PermaBASE

Cement Board

General: All framing should comply with local building code requirements and be designed to provide support with a maximum allowable deflection of L/360 under all intended live

(including wind) and dead loads.

Note: Cut or score PermaBASE on rough side of panel.

Control Joints: For exterior installations, consult finish manufacturer’s instructions for spacing requirements. For exterior tile applications, control joints should be spaced a maximum of every 12'. If no recommendation is available, allow a maximum of 16 lineal feet between control joints. A control joint must be installed but not limited to the following locations: where expansion joints occur in the framing or building (discontinue all cross furring members located behind joint); when boards abut dissimilar materials; where framing material changes; at changes of building shape or structural system; at each story separation.

Place control joints at corners of window and door openings or follow specifications of architect. Control joint cavity shall not be filled with coating or other materials.

WALLS AND CEILINGS

Wall Framing: Studs should be spaced a maximum of 16" o.c. Edges/ends of PermaBASE parallel to framing should be continuously supported. Provide additional blocking when necessary to permit proper PermaBASE attachment. Do not install PermaBASE directly over protrusions from stud plane such as heavy brackets or fastener heads.

(Edges of PermaBASE parallel to framing should be continuously supported.) Provide additional blocking when necessary to permit proper PermaBASE attachment.

Water Barrier: While PermaBASE is unaffected by moisture, a water/air resistive barrier (WRB) must be installed to protect the cavity. The type and specific placement or location of the water barrier will vary based on local building codes and/or manufacturers' warranties. Consult the WRB manufacturer’s recommendations for specific installation guidelines.

PermaBASE Cement Board: Apply PermaBASE with ends and edges closely butted but not forced together. Stagger end joints in successive courses. Drive fasteners into field of cement board first, working toward ends and edges. Space fasteners maximum

8" o.c. for walls, 6" o.c. for ceilings with perimeter fasteners at least 3/8" and less than 5/8" from ends and edges.

Joint Reinforcement: Trowel bonding material to completely fill the tapered recessed board joints and gaps between each panel. On non-tapered joints, apply a 6" wide, approximately 1/16" thick coat of bonding material over entire joint. For all joints, immediately embed 4" alkali-resistant fiberglass mesh tape fully into applied bonding material and allow to cure. Same bonding material should be applied to corners, control joints, trims or other accessories. Feather bonding material over fasteners to fully conceal.

DECKS

Subfloor: Plywood should be securely glued and fastened to floor joists spaced a maximum of 16"o.c. Subfloor should be sloped at a minimum pitch of 1/4" per foot. The floor surface should be true to plane within 1/8" in 10'.

Underlayment: Using a 1/4" square-notched trowel, apply a setting bed of dry-set mortar to the subfloor. Immediately laminate PermaBASE to subfloor, leaving a 1/8" space between boards at all joints and corners. Leave a 1/4" gap along walls.

Stagger joints so they do not line up with underlying substrate joints. Fasten PermaBASE every 8" o.c. throughout board field and around all edges while setting bed mortar is still workable.

Around perimeter of each board, locate fasteners 2" from the corners and not less than 3/8" from the edges. Fill all joints solid with bonding material. On non-tapered joints such as butt ends, apply a 6" wide, 1/16" thick coat over the entire joint. For all joints, embed alkali-resistant fiberglass mesh tape fully into applied bonding material; ensure that tape is centered over joint. Apply bonding material over fasteners to fully conceal.

Exterior Installation of

PermaBASE CI™

WALLS

Wall Framing: Framing members should be spaced a maximum of

16" o.c. and shall be a minimum of 2"x 4" nominal (wood) or 20 gauge (metal). Edges of PermaBASE CI™ Insulated Cement Board parallel to framing should be continuously supported. Provide additional blocking when necessary to permit proper attachment.

Water Barrier: While PermaBASE CI Insulated Cement Board is unaffected by moisture, a water/air resistive barrier (WRB) must be installed to protect the cavity. The type and specific placement or location of the water barrier will vary based on local building codes and/or manufacturers' specifications, installation guidelines and warranties. Consult the WRB manufacturer’s recommendations for specific installation guidelines.

PermaBASE CI Insulated Cement Board:

Note: PermaBASE CI can be cut using three methods:

1. Score PermaBASE CI from the foam side using a utility knife to score/cut completely through the insulation and into the back of the cement board. The board can then be snapped. Cut through the mesh on the front of board to complete the cut.

2. PermaBASE CI can be cut to length effectively with a hand saw.

3. While wearing the proper protective equipment such as safety glasses and approved respirator, use a power saw with the appropriate blade to cut through the entire panel. Penetrations can be created in the panel with a drywall saw.

Apply PermaBASE CI with ends and edges closely butted, but not forced, together. Stagger end joints in successive courses. Drive fasteners into field of cement board first, working toward ends and edges. Space fasteners maximum 8" o.c. with perimeter fasteners at least 3/8" and less than 5/8" from ends and edges.

Ensure PermaBASE CI Insulated Cement Board is tight to framing.

Do not overdrive screws to the point they penetrate the fiberglass mesh in PermaBASE CI.

Joint Reinforcement: Trowel bonding material to completely fill the tapered recessed board joints and gaps between each panel.

On non-tapered joints, apply a 6" wide, approx. 1/16" thick, coat of bonding material over entire joint. For all joints, immediately embed 4" alkali-resistant fiberglass mesh tape fully into applied bonding material and allow to cure. Same bonding material should be applied to corners, control joints, trims or other accessories.

Feather bonding material over fasteners to fully conceal.

Control Joints: For exterior installations, consult finish manufacturer for spacing requirements. For exterior tile applications, control joints should be spaced a maximum of every

12'. If no recommendation is available, allow a maximum of 16 lineal feet between control joints. A control joint must be installed but not limited to the following locations: where expansion joints occur in the framing or building (discontinue all cross-furring members located behind joint); when boards abut dissimilar materials; where framing material changes; at changes of building shape or structural system; at each story separation. Place control joints at corners of window and door openings or follow specifications of architect. Control joint cavity shall not be filled with coating or other materials.

LIMITATIONS

• Treat joints with 4" wide alkali-resistant fiberglass mesh tape set in a modified mortar or stucco basecoat.

• Steel framing must be minimum 20-gauge (galvanized) (.0312” design thickness) or heavier.

• Do not expose PermaBASE CI to temperatures over 220˚F

(105˚C).

• Do not use PermaBASE CI as a nailing base for other finishes.

• Thin veneer construction can reveal planar irregularities in framing.

• Minor cracking at joints may become visible in finished exterior surface.

• For exterior finishes applied directly to PermaBASE CI, reinforcing mesh must be embedded in basecoat (consult exterior finish manufacturer for additional installation requirements).

• Sheathing selection and installation varies according to type of wall construction.

Advantages of Creating Continuous Insulation with

PermaBASE:

• Provides better thermal comfort, lowers heating and cooling costs, reduces likelihood of trapped moisture.

• Helps mitigate the loss of heat/air conditioning by insulating the studs.

• Allows multiple finishes on one substrate.

• Works in all climates – adaptable to varying regional system requirements.

• 15-year exterior warranty.

• Speeds up your schedule – faster to install than traditional method.

24 | PermaBASE Building Products

Continuous Insulation with PermaBASE CI

As building codes and building insulation requirements become increasingly stringent, you can count on PermaBASE products to help meet your substrate needs for Continuous Insulation (CI).

CI on the exterior envelope helps to eliminate air and moisture leakage as well as reduce thermal bridging, or the heating/ cooling loss transmitted through steel studs. With PermaBASE

CI, designers and contractors have a simpler, faster method of achieving continuous insulation. PermaBASE® Cement Board has also been used for years to install the final exterior finish over the exterior insulation in applications including Z-furring channels, batten strips and direct fastener applications. PermaBASE CI and

PermaBASE Cement Board can be used in all types of construction, including commercial, residential and multi-family.

MOLD AND MILDEW RESISTANCE

PermaBASE was designed to provide extra protection against mold and mildew. When tested by an independent laboratory, PermaBASE received the highest possible ratings on ASTM G 21 and D 3273. The use of PermaBASE in actual installations may not produce the same results as were achieved in controlled laboratory conditions.

No material can be considered “mold-proof,” nor is it certain that any material will resist mold or mildew indefinitely. When used in conjunction with good design, handling and construction practices, PermaBASE can provide increased mold resistance. As with any building material, avoiding water exposure during handling, storage and installation, and after installation is complete, is the best way to avoid the formation of mold or mildew.
