Surface Preparation

Pro Tip: Never skip the primer. Primer keeps the water in the leveling compound from absorbing too rapidly into the subfloor, which prevents cracking, bubbling, and weak bonding.
Surface prep products are the foundation of any flooring installation. They are specialty formulations that help ensure ideal adhesion, block moisture, and create a perfectly smooth, level subfloor for a beautiful, professionally finished floor.
A primer like ROBERTS FS400 First Step Primer can help you ensure proper adhesion of flooring to porous substrates. It prevents over-absorption of adhesives to create a uniform finish and can help protect the adhesive and flooring from alkalinity. The greatest advantage is that it provides a better adhesion surface for a professionally finished floor.
When old flooring is ripped up, stubborn, reactive adhesive (like black asphalt-based cutback or pressure-sensitive glue) is often left behind – and you need an adhesive residue isolator like ROBERTS FS410 First Step Encapsulator, a high-strength polymer formulated to isolate adhesive residues including old cutback, and to provide a clean, neutral surface ready for new adhesive - and to ensure proper bonding.
