PRIMER P360

PRIMER P360 is a breakthrough acrylic copolymer primer technology with alkali resistance to pH 14 while providing superior bond to substrates when used with Dependable Self-leveling underlayments (SLUs).

PRIMER P360 is suitable for a wide variety of porous and non-porous substrates making it the only required primer in typical SLU installations. Designed with installers in mind PRIMER P360 offers maximum versatility, ZERO VOCs, fast drying, tremendous coverage and easy handling.

Preparation and Application

General Guidelines

• For use in dry, interior applications environments only
• Not for installation over materials containing asbestos
• For application when substrate and ambient conditions are between 50-90ºF (10-32ºC)
• Moisture limits (RH or Moisture Vapor Emissions Rate (MVER)) are determined by the finished flooring and associated adhesive)
• Concrete surface temperatures must be at least 50ºF (10ºC), above the dew point and rising prior to application
• Not suitable for use over luan, plastic, fiberglass, particle board, sheet vinyl, and other dimensionally unstable materials.
• Installation must conform to applicable local, state and federal building codes

PREPARATION AND APPLICATION

Surface Preparation

All surfaces must be dry, sound, stable, and clean. Ensure surfaces are free from dust and dirt and any bond breaking materials (silicates, curing compounds, oils). Mechanically remove weak surfaces and any contaminants to sound surface. Always finish cleaning by a final removal of contaminants by vacuum.

Application Procedures
FOR PROFESSIONAL USE ONLY
Use chemical resistant gloves when handling.

Mixing

To address any settling, mix PRIMER A™ 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 PRIMER 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 Primer 3:1 (water:primer). Ensure the substrate stays wet for at least 15 minutes. Substrates that “ash dry” may require additional dilution, or other remedial actions. If substrate does not stay wet at least 15 minutes, contact Dependable Technical Support. Gypsum substrates tend to be very absorbent and may require additional dilution.

Once diluted use a push broom with fine tips and spread PRIMER P360 with the broom working it back and forth across the surface to ensure penetration into the pours 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

(Wood, VCT, Adhesive Residues, Cement Terrazzo, Moisture Membranes). Apply undiluted PRIMER P360 with a paint or dual cage roller using a 3/8” nap roller. Spread to ensure the entire surface is covered with a thin, even film, avoiding puddling. If material puddles, spread uniformly across substrate.

Dry Time

Ambient conditions (temperature, humidity, air movement) will impact dry time. Universal Primer 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 or in the case of contamination by dust or foreign material.

Clean-up and Disposal

Wash hands and tools with water before the PRIMER P360 dries to a film to ensure easiest removal. Dispose of waste in accordance with all local, state and federal regulations.

Storage

Store in cool and dry conditions, out of direct sunlight in sealed containers. DO NOT ALLOW TO FREEZE. If material freezes, dispose in accordance with local, state and federal regulations.
