Application Procedures
FOR PROFESSIONAL USE ONLY
Use chemical resistant gloves when handling.
Mixing
To address any settling, mix P360 briefly with a low speed (300 rpm) mixer and paint paddle to ensure all contents are homogenous (typically 30 seconds). Use full strength as directed. When specific substrates require the dilution of P360, mix again after diluted to the desired ratio with low speed mixer (typically 1 min). Remix diluted material if it sits more than 24 hours.
Material Application
Substrates can be tested for absorbency onsite. Place a bottle-capful of clean water on the substrate, if it readily disappears into the substrate, substrate is absorbent.
Absorbent Substrates
(Typically concrete, gypsum); Dilute PLATFORM P360 3:1 (water:primer).
Ensure the substrate stays wet for at least 15 minutes. Substrates that “flash dry” may require additional dilution, or other remedial actions. If substrate does not stay wet at least 15 minutes, contact Platform Technical Support. Gypsum substrates tend to be very absorbent and may require additional dilution. In many cases gypsum requires primer dilution of 6:1 (water:primer) or even 10:1 to maintain desired wet surface for 15 minutes.
Once diluted, use a fine tip push broom to spread PLATFORM P360 back and forth, working it into the surface to ensure penetration into the pores of the substrate. Avoid allowing the material to puddle, rather spread any puddles uniformly across the surface. Some highly porous surfaces may require an additional primer coat (primer effectiveness can be water tested with a capful of water after it has dried).
Non-Absorbent Substrates
(VCT, Adhesive Residues, Cement Terrazzo, Moisture Membranes, Epoxy). Apply undiluted P360 with a 3/8" nap paint roller or dual-cage roller. Spread to ensure the entire surface is covered with a thin, even film, avoiding puddling. If material puddles, spread uniformly across substrate. Not for use over water soluble adhesives or pressure sensitive adhesives. In those cases, remove adhesive prior to priming.
Double prime all wood substrates with P360 NEAT. Spread to ensure the entire surface is covered with a thin, even film, avoiding puddling. If material puddles, spread uniformly across substrate. Ensure the first coat of primer dries completely prior to installing the second coat of primer.
Dry Time
Ambient conditions (temperature, humidity, air movement) will impact dry time. P360 typically dries in 45 minutes to 90 minutes. Roll out to a uniform film with no ridges or primer build. Areas must be re-primed if more than 48 hours passes since Primer P360 application, or in the case of contamination by dust or foreign material.
