Description
xSchluter®-PRIMER-U is a ready-to-use, one-component, solvent-free, 100% acrylic, water-based primer.It is used to ensure excellent adhesion when applying Schluter thin-set mortars to difficult-to-bond-to floor and wall surfaces such as gypsum underlayment, raised access panels, and existing tile. For floor surfaces these include gypsum underlayment, raised access panels, and existing tile. For wall surfaces, this includes suitable solid backing.
PRIMER-U is suitable for use with Schluter SET®, Schluter ALL-SET®, and Schluter FAST-SET® in interior applications where increased adhesion is required over various porous and non-porous substrates.
PRIMER-U is a translucent orange liquid that dries to a slightly glossy film approximately 15 - 60 minutes after application. PRIMER-U provides a strong bond to gypsum underlayment, concrete, existing tile, glass, plywood and OSB subfloor panels, terrazzo, steel, VCT flooring, well-bonded flooring adhesive residue, and latex paint.
Ideal for use with Schluter SET®, ALL-SET, and FAST-SET thin-set mortars, and Schluter underlayments such as Schluter®-DITRA and DITRA-HEAT
Ready-to-use, single-coat application with roller or broom
One-component, solvent-free, water-based acrylic formulation
Low odor and zero-VOC
Freeze/thaw stable
Drying Time: The drying time of PRIMER-U depends on the porosity of the substrate, the air temperature and relative humidity. Under average drying conditions of 70°F (21°C) and 55% RH, PRIMER-U will dry in 15-60 minutes. Protect from exposure to moisture for at least 4 hours.

Install Steps:
Surface Preparation: The surface where PRIMER-U is to be applied must be structurally sound, clean, smooth, dry, and free of moisture. Any contaminants (i.e., paint, grease, oil, sealers, curing compounds, etc.) and/or flooring adhesive that is not well adhered or may prevent proper bond must be removed. Thoroughly clean surface to remove dirt and debris.
Mixing: Solid resin may settle during shipping and storage. Stir or mix thoroughly before use. Do not dilute.
Application: The application area shall be fully enclosed, weather tight, with an operating HVAC system. PRIMER-U must be acclimated to ambient conditions and applied when the ambient temperatures are between 65°- 85°F (18 - 29°C). Prior to PRIMER-U placement, the installation surface/ application area must be acclimated to ambient conditions between 65°- 85°F (18 - 29°C). Ensure the primer and application area are acclimated for 48 hours prior to use. The relative humidity of the application area shall be maintained between 35-55%. Carefully read all instructions before application. Do not dilute primer. Pour an adequate amount of primer from container directly onto the substrate or pour primer from container into a paint tray.
1. Apply a thin, even coat using a 3/8" (10 mm) medium-nap paint roller, or a similar brush, broom, sponge, or garden-type sprayer. A foam roller is recommended for non-porous substrates (e.g., polished porcelain) and wall surfaces. Do not leave any bare spots or excessive amounts of primer. Keep roller wet throughout the application process.
2. Once applied, the primer must be allowed to dry to the touch and not transfer to finger. Allow the coat to dry fully before applying thin-set mortar. Note: If PRIMER-U remains uncovered for more than 48 hours, apply a second coat.
Clean Up: Clean roller or brush with water while PRIMER-U is still wet. Remove wet primer from tools and equipment with soapy water and a clean cloth. Use mineral spirits to remove dried primer. Use caution when handling flammable solvents.
Drying Time: The drying time of PRIMER-U depends on the porosity of the substrate, the air temperature and relative humidity. Under average drying conditions of 70°F (21°C) and 55% RH, PRIMER-U will dry in 15-60 minutes. Protect from exposure to moisture for at least 4 hours.
