CEMIX SUPER PRIMER is a water-based primer used for improving the adhesion of CEMIX products to smooth, dense and various non porous substrates. It is easy to apply with a brush or roller with applications of subsequent products able to take place with minimal downtime. Specially formulated, ready to use primer, that enhances bond to non-porous surfaces or substrates. CEMIX SUPER PRIMER is suitable for internal and external wall or floor applications.


Cemix Super Primer is compatible with subsequent applications of CEMIX manufactured tile adhesives, floor levelling compounds and in non fully immersed conditions with CEMIX manufactured undertile waterproofing membranes. For use on to smooth, dense and nonporus surfaces.

SUBSTRATE PREPARATION The surface to be primed must be clean, firm and free of dust, dirt, oil, grease, curing compounds, release agents and degraded and unsuitable old surface coatings. Ensure surfaces are dry prior to application, with no residue or permanent dampness. Surfaces must be suitable for the application of the subsequent product being used. APPLICATION Stir product before use. Spread the material using a brush or long nap roller to cover at a rate of 6 - 10m2 per litre over the entire surface to be primed. For floor levelling toppings application and highly absorbent substrates dilute with water 1:1 by volume. All tools should be cleaned with water immediately after use. DRYING TIME Ensure the CEMIX SUPER PRIMER is fully dry prior to the application of subsequent products, allow approximately 20 minutes at 23ºC and 50% relative humidity. Type of substrate being primed, porosity and climatic conditions will affect drying times, allow longer for lower temperatures or high relative humidity. COVERAGE One litre will cover approximately 6 - 10m2 depending on porosity of the surface and the method of application. SHELF LIFE A shelf life of 12 months is expected when stored in a dry place in original unopened packaging, at 23°C and 50% relative humidity.
