Concrete substrates should have a minimum 28 day cure and be free of all bond-inhibiting contaminants. 2. High-pressure water blast (or abrasive blast on hard, dense surfaces) surface to medium grit sandpaper texture (reference ICRI guide 03732 SP 3). 3. Repair any holes, spalled and damaged concrete with appropriate BASF Construction Chemicals repair materials. Remove any protruding concrete accessories and smooth out any irregularities. 4. Some stains may require chemical removal. Be sure to neutralize the compounds and rinse with clean water. 5. Remove any blisters or delaminated areas and sand edges to smooth rough areas and provide transition to old paint areas. 6. Check adhesion of old paint using ASTM D 3359, measuring adhesion by Tape Method A. 7. Treat cracks greater than 1/32” with (brand) Knife Grade or Brush Grade patching compound. Treat cracks larger than 1/4” as expansion joints and fill with appropriate BASF Construction Chemicals sealant. Detail work ™ 1. Apply NP 1 (see Form No. 1017906) where appropriate on support columns and other details. Inspect all expansion joints. Ensure there is no deteriorated sealant, adhesion loss, or nonelastomeric caulking in joints. Repair all defective sealant or caulk with NP 1™ or Sonolastic® 150. 2. Apply and tool a liberal amount of Patching Compound or form a cant bead of NP 1™ or Sonolastic® 150 wherever there is change in direction where 2 walls abut and at column and wall intersections. 3. If movement is anticipated where dissimilar substrates join (e.g., stucco and concrete or brick and block), properly clean the joint and seal with NP 1™ or Sonolastic® 150. 4. Inspect all through-wall penetrations, including electrical, lighting, signage, plumbing, HVAC, and fire-sprinkler piping, for a watertight seal. Repair with NP 1™ or Sonolastic® 150. 5. Inspect all flashings, including cap flashing and roof flashing for watertight seals. Repair with NP 1™ or Sonolastic® 150. 6. Recaulking of old windows is essential in the waterproofing and renovation of existing structures. Inspect perimeter joints and mullions and recaulk with NP 1™ or Sonolastic® 150 (see Form No. 1017906 or Form No. 1026309) as required. Allow sealant to cure before proceeding. 7. All stucco and masonry window sills (primed, if required) should receive a coat of brush-grade Patching Compound. Create a smooth surface that drains away from the window. 8. Cracks smaller than hairline can be bridged with knife-grade or brush-grade Patching Compounds. 9. Chip or grind out nonmoving cracks larger than hairline. Remove dust and pack with knife-grade Patching Compound 748. Bridge crack with brushgrade Patching Compound 750. Brush a narrow band directly into the crack using brush, sponge, or other means to match substrate texture and reduce telegraphing of the patches through the finish coat. On textured substrates, texturized Patching Compound may be used to minimize the telegraphing. SONNEBORN® PRODUCT DATA SILFLEX® Yield Wet and Dry Film Thickness FT2/GAL (M2/L) PER COAT AVERAGE DRY FILM MILS (MM) AVERAGE WET FILM MILS (MM) 50 (1.23) 14 – 15 (0.35 – 0.38) 32 – 33 (0.81 – 0.83) 60 (1.47) 12 – 13 (0.30 – 0.33) 26 – 27 (0.66 – 0.68) 80 (1.96) 9 – 10 (0.23 – 0.25) 20 – 21 (0.51 – 0.53) 100 (2.45) 7 – 8 (0.18 – 0.20) 16 – 17 (0.41 – 0.43) Coverage rates are theoretical on smooth-surfaced, properly primed substrates. IMPORTANT: Warranty applications require a minimum 12 dry mils (0.30 mm) film thickness. 10. Rout out dynamic or moving cracks to a minimum of 1/4 by 1/4" (6 by 6 mm), then fill with NP 1™ or Sonolastic® 150. Once sealant is tooled and cured, proceed with crack repair as described previously. 11. Repair cracks and treat back side of parapets in the same manner as exterior walls, terminating at roof counter flashings. If top of parapet wall is exposed masonry, apply a coat of Patching Compound to create a smooth, well-draining surface. Recaulking of reglet may be required. 12. Block and other porous surfaces should be clean, dry, and free of contaminants. Fill concrete block faces with 1 nylon brush coat of Block Filler 749. Apply by working material into pores, crevices, and voids. Allow Block Filler to dry, typically 24 – 48 hours, before proceeding. Coverage rate depends on the porosity and texture of the block surface. Apply to dry, cured block and mortar only. See product data sheet for complete application instructions. Priming 1. Prime all uncoated concrete and masonry substrates (except those treated with Block Filler 749) as follows: dilute Silflex® 10% with clean water and apply at the rate of 80 – 100 ft2/gallon (2.0 – 2.5 m2/L). 2. If an existing coating is properly cleaned and chalking still occurs, it must be primed with Chalky Surface Primer VOC. An existing coating totally free of chalk does not require priming. Allow Chalky Surface Primer VOC to dry approximately 2 – 4 hours before topcoating. Application 1. Apply Silflex® finish coat at the appropriate rates listed under Coverage section. 2. Apply the finish coat in a pinhole-free, continuous membrane for waterproofing integrity. ROLLER For Best Performance 1. Use a medium synthetic-nap (3/4") quality roller cover for smooth surfaces. Use a long synthetic nap roller for rough surfaces. • Apply a 4 by 4 ft (1.2 by 1.2 m) test area to verify acceptable color and adhesion before proceeding with any project. 2. Completely saturate the roller and keep it loaded with the coating to build the required mils. Never dry roll except for touch up. • Keep from freezing. 3. Roll the coating in a consistent fanlike pattern to achieve uniform mil thickness. Stroke variations may result in an uneven texture. • Do not apply when surface or ambient temperatures are less than 40° F (4° C) or are expected to go below 40° F (4° C) for 12 hours following application. • Do not apply coatings in rain, snow, or fog. BRUSH • Do not thin Silflex® finish coat. 1. Application by brush is recommended only for small inaccessible areas, e.g., on touch-ups. • Hot or dry conditions limit working time and accelerate drying; cool or damp conditions extend working time and retard drying and may require added measures for protection against wind, dust, dirt, rain, and freezing. 2. Use nylon or synthetic-bristled brushes only. SPRAY 1. For spray equipment recommendations, refer to the equipment manufacturer. As a general guideline, use an airless sprayer providing up to 3,300 psi (22.75 MPa) pressure and utilize 0.03 – 0.035 tip size. 2. A 10% spray loss should be anticipated. 3. On porous substrates, pinholing is an indication of entrapped air. Backrolling is required to eliminate pinholing. Drying Time Dry time is 12 hours under normal conditions (75° F or 24° C and 50% relative humidity). Drying time will vary with application rates, temperature, and humidity. Clean Up Clean Silflex® from brushes, rollers, sprayers, and other equipment with water immediately after application. • Minimum dry time between coats is 12 hours at 75° F (24° C) and 50% or less relative humidity. • Color formulas containing organic colorants are susceptible to fading in exterior applications. Refer to Sonneborn® tint manual for guidance. • Ultra-deep and neutral-base colors are mainly intended for use as accents in small areas only; they are not guaranteed against fading. • Slower drying time should be expected when using ultra-deep or neutral base colors. • Do not apply to traffic-bearing or flat surfaces. • On porous substrates, pinholing is an indication of entrapped air; backroll to eliminate pinholing (overaggressive backrolling, however, may create pinholes). • Iron-rich slag aggregate containing block, mortar, or brick may cause discoloration through Silflex®. Consult Technical Service for recommendations.
