Ultra Tile Fix ProPrimer is an advanced polymer primer for exceptional bonding to multiple substrates. It can be used on walls or floors and is designed for both porous and non-porous substrates.
Ultra Tile Fix ProPrimer is suitable for: Concrete, sand/cement screed, plywood overlay (15mm min), tile backer boards, cement-faced fibre boards, anhydrite screeds, tile on tile, firm and stable plaster, plasterboard, sand/cement render, concrete brick/block, hard vinyl tiles, and flooring grade asphalt.
Ultra Tile Fix ProPrimer has been specifically developed to be used as a primer for use with cementitious tile adhesives to provide improved sealing and bonding properties for a variety of substrates.
Ensure the application area is thoroughly dry and in a sound and stable condition. The surface must be free from contaminants that may hinder adhesion such as dust, oils and grease. All laitance and surface treatments must be removed. Surfaces must be roughened by mechanical scabbing to enhance the key. All surfaces should be free from dust and thoroughly clean before the primer is applied. Underfloor heating must be switched off for at least 48 hours before and after application. When applying Ultra Tile Fix ProPrimer onto a calcium sulphate screed the following preparation should also be considered in addition to the above. It is particularly important that calcium sulphate screeds are ensured dry and below 75%RH. These screeds are also prone to surface laitance and therefore should be mechanically abraded to remove this weak surface.
The product should be applied using a brush or roller and scrubbed well into the surface to avoid pooling. Allow to fully dry. For multi-coats, ensure each coat dries before you apply the next.
Ultra Tile Fix ProPrimer should always be diluted before use.
1st coat: 3 parts water/1 part primer
2nd coat: 1 parts water/1 part primer
Very absorbent subfloors will always require a 3rd coat at 1 parts water/1 part primer. Under good drying conditions, the product should be ready to receive an additional coat after 1-2 hours.
1 coat, neat.
