Joint Design

Joints < 10 mm are normally designed for crack control and therefore they are not movement / expansion joints. The joint width to depth ratio is important at the time of the application of the sealant (guide value of +10°C).

All joints must be properly designed and dimensioned by the specifier and the main contractor in accordance with the relevant standards, because changes are not usually feasible after construction. The basis for calculation of the necessary joint width are the technical values of the joint sealant and the adjacent building materials, plus the exposure of the building, its method of construction and its dimensions.

Substrate Quality

The flush joint design rules out trip hazards and dirt traps.

The recessed joint design protects the sealant against mechanical loads.

Clean and dry, homogeneous, free from oils and grease, dust and loose or friable particles. Cement laitance must be removed.

Substrate Preparation /

Priming

Non porous substrates:

E.g. metals, powder coatings etc. have to be cleaned with a fine abrasive pad and

SikaCleaner-205 by using a clean towel / cloth.

After a flash off time of at least 15 min, apply SikaPrimer-3 N by using a brush.

Before sealing allow a flash off time of at least 30 min. (max. 8 hrs.).

For PVC use SikaPrimer-215.

Before sealing allow a flash off time of at least 30 min. (max. 8 hrs.).

Porous substrates:

E.g. concrete, aerated concrete and cementitious renders, mortars, brick, etc. have to be primed with SikaPrimer-3 N by using a brush.

Before sealing allow a flash off time of at least 30 min. (max. 8 hrs.).

Important note:

Primers are only adhesion promoters. They neither substitute for the correct cleaning of the surface nor improve their strength significantly.

Primers improve long term performance of a sealed joint.

PRO-3 WF is supplied ready to use.

After suitable joint and substrate preparation, insert Backing Rod to required depth and apply primer if necessary. Insert cartridge into sealant gun and firmly extrude

Sikaflex PRO-3 WF into joint making sure that it is full contact with the side of the joint. Fill the joint, avoiding air entrapment. Sikaflex PRO-3 WF must be tooled firmly against joint sides to ensure good adhesion.

Masking tape must be used where sharp exact joint lines or exceptionally neat lines are required. Remove the tape whilst the sealant is still soft. Sleek joint with smoothing liquid for a perfect sealant surface.

Clean all tools and application equipment with Sika Sealant Remover / Sika

TopClean-T immediately after use. Hardened / cured material can only be removed mechanically.

Elastic sealants may not be over painted.

Compatible coatings may cover the joint sides to max. 1 mm.

The compatibility must be tested according to DIN 52 452-2.

Colour deviations may occur due to exposure to chemicals, high temperatures, UVradiation (especially with colour shade white). However a change in colour will not adversely influence the technical performance or the durability of the product.

Before using on natural stone contact our Technical Service.

Do not use Sikaflex

®

PRO-3 WF as a glass sealer, on bituminous substrates, natural rubber, EPDM rubber or on building materials which might bleed oils, plastisicers or solvents which could attack the sealant.

Do not use Sikaflex

®

PRO-3 WF to seal swimming pools.

Do not mix with or expose uncured Sikaflex

®

PRO-3 WF to substances that may react with isocyanates, especially alcohols which are often components within e.g. thinners, solvents, cleaning agents and formwork releasing compounds. Such contact could interfere or prevent the cross linking curing reaction of the material.
