Wykamol EP40 Epoxy Floor Coating Primer Usage Instructions

SUBSTRATE PREPARATION
All substrates should be dry, clean and free from laitance, oil,grease and other contaminants. Ideally, concrete surfaces should be vacuum shotblasted or mechanically abraded (grinding) to both clean and open the suface, providing a good mechanical key.
Please note: Following sufficient substrate preparation, EP40 Epoxy Floor Primer should always be applied prior to the application of either the grey or clear finish coat.
Substrate humidity should be ≤ 80% before application commences. The concrete subbase must be ≥ 25 N/mm² as per BS 8204-6.
The subbase must be level and have no more than 2 mm undulations. If floor unevenness is significant a polymer modified C35 screed can be used to level. Contact the Wykamol Technical Department for more information.

MIXING
EP40 Epoxy Floor Primer and Finish Coat are both made by combining two components; part A and part B. The part A container is large enough to act as a mixing vessel when combining part A and part B.
By hand, thoroughly mix both part A and part B in their own vessels before combining. Add the entire contents of part B to the entire contents of the part A vessel and mix thoroughly.
Ideally, use a mechanical mixer under low shear to combine, ensuring minimal air entrapment. Do not allow mixture to sit for any considerable amount of time before applying, as it will begin to harden.

APPLICATION
EP40 Epoxy Floor Primer:
1. Using a stiff brush or roller, work the product into the substrate, ensuring all areas are completely covered.
2. Allow to cure for at least 12 hours prior to applying a EP40 Epoxy Finish Coat. If atmospheric or substrate temperatures are below 20°C, allow for a longer initial curing time. Product should be just tack free.
3. Do not allow Primer to fully cure – do not allow curing time to exceed 26 hours before applying a 2nd coat of Primer or Finish Coat.

Pot life 45 mins – 1.5 hours
Recoat time (cure at20°C)** 12 – 26 hours (or when just tack free)
Full chemical cure (at 20°C)** 7 – 14 days
