Custom Building Products' new  Multi-Surface Bonding Primer is a ready-to-use, single component, water-based primer engineered to deliver adhesion on a variety of substrates where proper bonding can be difficult.

Formulated with aggregates and polymers that promote mechanical bonds over both porous and non-porous substrates, Custom's Multi-Surface Bonding Primer also requires no shot blasting or grinding in most cases, making it especially easy to use.

“Custom Buildings Products’ Multi-Surface Bonding Primer offers a safe, acrylic based formula that is ideal for a variety of substrates while offering the best adhesion on even the most difficult surfaces,” said Eric Carr, director of construction channel marketing for Custom Building Products. “Along with it requiring no mixing of multiple components, this single-component primer is easy to apply in one coat for most applications with either a roller or a brush.”

Engineered to provide unmatched adhesion on difficult substrates, Custom's Multi-Surface Bonding Primer effectively bonds to cement-based mortars, tile adhesives and self-leveling underlayments. It works on surfaces such as tile over tile, vinyl substrates, epoxy-based substrates, metal, and other difficult-to-bond surfaces. It also can be used as a primer for some resin-backed tile.
