Sika® Prohesive Proflex is suitable for:- Fixing tile & Stone by Thin-Bed application
- Medium-Bed applications up to 10mm.
- Internal & external applications
- Floor & wall applications
- Ceramic Tiles
- Porcelain Tiles
- Glass Mosaics
- Mosaic Tiles
- Natural Stone (non moisture sensitive)
- Concrete (concrete above 35 MPa requires mechanical preperation prior to fixing)
- Compressed cement boards*
- Ceramic tile underlay / fibre cement boards*
- Existing tiles (used in conjunction with Eco Systems PREP N PRIME)
- Brick masonry
- Concrete masonry
- Sika Approved Waterproof Membranes
- Cement mortar beds / screeds (must be minimum 24 hours old at 23°C & 50% relative humidity)
- Gypsum plaster board*
- Sika approved accoustic mat
MIXING
Pour clean cool water into a mixing container and gradually pour the the Sika® Prohesive Proflex powder into the container and stir with a slow speed mixing drill (approx 500rpm). Mix for 2-3 minutes to a smooth lump free homogeneous consistency. Allow the product to stand (slake) for 5 minutes then restire for an additional minute. Do not add more water. Restirring the mixture may be required during the adhesives pot life.
APPLICATION
Tiles shall be fixed in accordance to with AS 3958.1-2007.
- Ensure the backs of tiles are clean and free from dust and contaminates.
- Apply the adhesive to the substrate with the appripriate sized notched trowel to achieve coverage requirement on both substrate and the back of the tile. Tiles may require back-buttering to acheive minimum coverage requirements.
- Apply the adhesive with a notched trowel in a single direction. Apply the tile, while pressing into the wet adhesive, break the ridges with the tile to fully bed the tile into the adhesive.
- It is advisable to periodically check the backs of the tiles for adhesive coverage requirements as the AS3958.1-2007.
- Only apply as must adhesive that can be covered prior to adhesive skinning. If skinning occurs remove and replace with fresh adhesive.
- Remove any excess adhesive from the face of the tile with a damp sponge and ensure grout joint are of uniform depth.
- Movement, expansion and control joints must be installed as per AS 3958.1-2007.
- For tile over tile applications, existing tiling must be adequately cleaned prior to application. Ensure existing tiling is sound and free from defect. Prime existing tiles with Prep n Prime and allow to dry. Gloss or polished tiles must be mechanically prepared prior to priming with Eco Prep n Prime.
CLEANING OF TOOLS
Tools and equipement can be cleaned with water while the adhesive is still wet.
