DESCRIPTION

Primer T is a low-VOC, water-based acrylic primer that enhances the performance

and adhesion of self-leveling underlayments (SLUs) on nonabsorbent surfaces

such as ceramic tile, vinyl composition tile (VCT), epoxy moisture barriers and

adhesive residue, as well as profiled, absorbent surfaces. Suitable for a wide

variety of substrates, Primer T combines excellent versatility with an easy, low-

odor application.

FEATURES AND BENEFITS

• One-component, versatile primer for a wide variety of substrate

conditions

• Low odor and VOC compliance for safe use in interior, occupied

environments

• Single-coat application for faster turnaround and lower installation costs

• Easy handling and application

WHERE TO USE

• Use Primer T when applying a self-leveling underlayment on properly

prepared suitable substrates.

• Interior residential (apartments, condominiums and homes)

• Interior commercial (office buildings, hotel rooms and hallways,

restaurants and cafeterias)

• Interior heavy commercial (hotel lobbies, convention centers, airports,

shopping malls, grocery stores and department stores)

• Interior institutional (hospitals, schools, universities, libraries and

government buildings)

LIMITATIONS

• Do not install over any substrates containing asbestos.

• Substrate and ambient temperatures must be between 50°F to 90°F

(10°C to 32°C).

• In all cases, the surface temperature of the prepared concrete slab must

be at least 5°F (2,8°C) above the dew point to avoid condensation on the

concrete surface as Primer T dries.

• Protect from freezing.

• For moisture limits on this primer, refer to the moisture limits of the

product to be applied over it.

• Verify that the substrate is free of bond-inhibiting or bond-breaking

materials such as curing compounds and dust.

• For use only in dry, interior environments. Do not apply on wet substrates.
