Applications

Fortis 823 PRIME can be applied is best applied by roller. It can be also be applied by airless spray systems as long as all safety precautions have been taken. Mixed material should be poured out in ribbons across the area to be rolled. A microfibre 5-8mm NAP roller cover is recommended. For porous substrates, multiple wet on wet applications may be necessary.

MIXING

Ensure Fortis 823 PRIME Part A and B are shaken before pouring and mixing. The mixing ratio for Fortis 823 PRIME is 1 Part Resin (Part A) to 1 Part Hardener (Part B) by volume; graduated plastic mixing containers are recommended for measuring volumetric quantities. Part B is to be added to Part A and mixed at low speed with a Jiffy style mechanical mixer. Mix only enough material for immediate use. Mix until a smooth and homogeneous mixture is formed, free of striations. This should take approximately 1 minute. Ensure material from the bottom and edges of the pail are sufficiently mixed. Let material stand for 1 minute. Mix for an additional minute.

Surfaces

Concrete: Substrates should be clean and free of loose material, old coatings, curing membranes, oils, and grease. If applying over existing coatings adhesion should be tested by preparation of a small test area. Remove all potential contaminants. On new concrete surfaces, it is best to diamond grind the surface. Old surfaces are best diamond ground but it is possible to etch and clean the surface. Contact Fortis if unsure. New concrete must be cured for a minimum of 28 days before the application.
