Any tile installer knows that not all substrates are created equally, and some varieties can pose adhesion challenges for thin-set mortars. These substrates would benefit from enhanced bond strength to ensure a fault-free installation, which is best achieved by using a primer.
Schluter is now launching a brand new ready-to-use universal primer to enhance adhesion of mortars to hard-to-bond surfaces. Schluter's Primer-U is ideal for use in interior applications where increased bond strength is needed. A water-based, solvent-free acrylic formulation, Primer-U is low odor and zero VOC, and is freeze/thaw stable facilitating shipping and storage.
Now, with Primer-U, thin-sets and membranes, installers have a complete system solution from Schluter. Primer-U will allow tile installers to get a single source warranty for their tile installation systems with guaranteed product compatibility.
Primer-U is ideal over various porous and non-porous substrates such as gypsum underlayment, existing tile, plywood or OSB, raised access panels and metal, and many more. It is easily applied in a single coat using a 3/8” nap roller, a wide nylon bristle brush or even a garden sprayer. Application is the same regardless of the substrate, and it dries in as little as 15 minutes.
Since Primer-U is a water-based solution, simply clean any tools or spills with water while the primer is still wet. It is available in 1-gallon and 5-gallon buckets.
