Thorough substrate preparation is essential.
- Ensure the floor is clean and all weak or loose paints or screeds are removed. Wire brushing is advisable. Sweep clean or vacuum.
- Once cleared, for floors with oil and grease contamination, this must be thoroughly cleaned with our Degrease IT then rinsed off and the substrate dried, before applying Cretex EP.
- Thoroughly stir both parts individually before mixing ensuring the resin is evenly dispersed, making sure you get right to the bottom of the container.
- Having fully prepared the substrate, mix the parts A and B together at a ratio of 1:1 to the quantity required, whether it be a complete unit, or a spoonful for a small repair. Ensure thorough mixing as an unmixed product will result in a poor or non-cure situation. Keep all components at room temperature 24 hours before use.
- Apply by a trowel, or by hand for a small, isolated areas, wearing suitable protective gloves.
- Being resin rich, Cretex EP had a typically sticky consistency and smoothing may be assisted by wetting the trowel using Polycote Solvent Cleaner as a release agent.
For vertical repairs:
- Where step nosing’s or expansion joint edges have broken away, the vertical face of the repair material should be supported to prevent slumping.
- Suitable sized wooden shuttering should be covered with polythene to reduce adhesion and should be removed as soon as the material is firm.
