This product is a smart choice for installers and homeowners who want consistent results, reduced installation risk, and better overall floor performance.
Dependable Primer and Additive is used to condition and strengthen subfloors prior to applying self-levelers, patching compounds, or adhesives. It helps control porosity, improves bonding strength, and promotes uniform curing, all key factors for a smooth, durable finished floor.
When mixed as an additive, it enhances flexibility and adhesion in compatible cement-based products, improving their workability and performance.
Formulated for dependable adhesion, this primer helps reduce issues like bubbling, pinholing, and premature failure caused by dusty or highly absorbent substrates. It penetrates the surface to create a strong mechanical bond, supporting better long-term flooring stability.
Its fast-drying, low-odor formula makes it suitable for occupied spaces and time-sensitive projects.
Dependable Primer and Additive is simple to mix and apply using common tools such as rollers, brushes, or sprayers. It spreads evenly and dries to a clear or slightly translucent finish, making it easy to see coverage without guesswork.
Installers benefit from improved flow and working time when used as an additive, while DIY users appreciate the straightforward application process.
Dependable Primer and Additive helps eliminate common floor prep problems that can compromise an installation. By improving bonding, consistency, and substrate readiness, it supports smoother installations and longer-lasting results, thereby saving time, materials, and callbacks.
It’s a practical, job-proven solution for anyone who wants confidence in their floor prep process, whether tackling a DIY project or a professional installation sourced through BuildDirect.
