LOW V.O.C. WATER-BASED EPOXY PRIMER/SEALER
PS-100 WB is a two-component epoxy sealing primer designed to increase the adhesion and coverage of American Safety Technologies flooring products on concrete, wood, tile and other porous substrates. This low odor and low VOC formula make it ideal for use in kitchens, hospitals, and other odor sensitive areas.
Easy to handle and apply, PS-100 WB penetrates deep into the surface ensuring good adhesion of the top coat.
New concrete should be wet cured for at least three days and allowed to dry with good ventilation for an additional thirty days.
After proper curing, new floors must be swept clean and all contaminants which might interfere with the adhesion of the coating system including laitance, curing membranes, surface hardeners, greases, and oils should be removed. An appropriate profile must be created using chemical or mechanical means.
The preferred method to prepare floor surfaces and to remove laitance, curing membranes and surface hardeners is by mechanical removal of the same with a portable shot blast cleaning machine.
Chemical cleaning of laitance and unbonded particles can be accomplished by etching the surface with a muratic acid or a buffered acid solution. Follow acid manufacturer’s application and safety instructions.
After the acid has finished reacting with the concrete the residue should be removed by a liberal fresh water rinse or preferably by power washing. Allow the surface to completely dry.
NOTE: Acid etching will not remove oil, grease or wax. If the acid does not bubble or foam when spread on the concrete, the surface should be examined for films of oil, grease, wax, curing membranes, hardeners or other sealers. If such film is present, it must be removed.
AGED AND UNCOATED CONCRETE FLOORS
Proceed as for New Concrete with particular emphasis on examination for grease, oil and chemical contamination and subsequent adequate cleaning.
PREVIOUSLY PAINTED SURFACES
The performance of American Safety Technologies’ anti-slip coatings applied over previously painted surfaces is directly influenced by the type, age, and condition of the old coating. Hard or glossy paints should be dulled by sanding, abrasive blasting or other abrasive methods to assure maximum adhesion.
A test patch should be applied to check for lifting or wrinkling of the old coating. If wrinkling or lifting occurs after overnight drying, remove the old coating.
A clean sound surface is required. Remove any dirt or oils from the surfaces with a commercial cleaner/degreaser and allow the surface to dry. Follow with sanding to remove loose or deteriorated surface and to obtain the proper surface profile.
Prep & Application Technique for PS-100 WB Primer
- PS-100 WB is a two-part epoxy. Pour the hardener into the container of base material and mix thoroughly with a drill and Jiffy® mixing blade for 3 to 5 minutes. Apply by using a short nap roller or brush.
- All American Safety Technologies topcoats can be successfully applied to a primed surface after 6 hours at 70°F (21°C).
Primed surfaces may be left exposed for up to 7 days. If the top coating is delayed more than 7 days, the area, after cleaning, should be brush-blasted and, the PS-100 WB reapplied.
Clean tools and spray equipment immediately after completing installation using soap and water.
Unlike conventional epoxies, PS-100 WB will not harden in the can. It will remain liquid after its 2-hour pot life. Therefore, no material should be used 2 hours after mixing as it will not cure properly.
See the technical data sheet for complete prep & application techniques.
