R.S Urethane High Build Blocking Primer (4:1) (Coming 2027)

R.S Urethane Blocking Primer

HIGH-ADHESION TANNIN & STAIN-BLOCKING HYBRID WATER-BASED URETHANE PRIMER

R.S Urethane Blocking Primer is an advanced high-viscosity, high-build water-based hybrid urethane primer engineered to provide exceptional stain, tannin, knot and discolouration-blocking performance across a wide range of challenging substrates.

Developed by the Infinity Effects Materials Science Division, its next-generation formulation combines powerful stain-blocking technology, exceptional adhesion and high-build performance to create a clean, stable and uniform foundation for subsequent Infinity Effects coating systems.

Designed for surfaces where a standard primer simply isn’t enough, R.S Urethane Blocking Primer creates a dense protective barrier that helps isolate problematic substrates and prevent unwanted stains and discolouration from migrating through the finished coating.

Roll It. Spray It.

Apply it your way — the Infinity way.

R.S Urethane Blocking Primer has been engineered for professional roller and spray application, giving installers the flexibility to choose the application method best suited to the surface and project.

Its high-build formulation provides excellent coverage, levelling and surface sealing, whether being rolled across larger areas or sprayed to achieve a smooth, consistent finish on detailed or complex surfaces.

Roll It. Spray It. Block It.

Next-Generation Stain & Tannin Blocking Technology

High-Build Formulation • Superior Stain Blocking • Exceptional Adhesion

R.S Urethane Blocking Primer has been specifically engineered to help control some of the most common and difficult causes of bleed-through and surface discolouration.

Its advanced barrier technology helps block and isolate:

Timber Tannins • Knots • Water Marks • Aged Staining • Rust Discolouration • Substrate Bleed-Through • Existing Surface Discolouration

This makes it particularly effective when working with timber, MDF and previously stained or problematic surfaces where tannins, knots and historic staining could otherwise compromise the appearance of the final coating.

High-Build Barrier Protection

Unlike conventional low-build primers, R.S Urethane Blocking Primer features a high-viscosity, high-build formulation designed to create a thicker and more uniform barrier across the substrate.

The dense coating helps seal and stabilise the surface while filling and levelling minor imperfections, creating a more consistent foundation for subsequent coatings.

This combination of surface sealing, stain isolation and high-build levelling helps installers achieve a cleaner, more professional final finish.

Exceptional Multi-Surface Adhesion

Engineered for outstanding versatility, R.S Urethane Blocking Primer provides strong mechanical adhesion across a wide range of correctly prepared substrates, including:

Timber • MDF • Concrete • Steel • Plaster • Drywall • Engineered Boards • Previously Coated Surfaces • And More

Its advanced hybrid urethane technology creates a strong, durable bonding layer between the prepared substrate and subsequent coating system.

The Ideal Foundation for Infinity Effects Systems

R.S Urethane Blocking Primer is designed to provide a stable foundation for a wide variety of Infinity Effects resin and water-based coating systems.

By isolating problematic staining while simultaneously creating a high-adhesion surface, it helps provide the clean, consistent base required for professional decorative and protective finishes.

This makes it particularly valuable for furniture restoration, timber coatings, kitchens, cabinetry, walls, architectural surfaces and renovation projects where the condition of the original substrate can significantly affect the final appearance.

Internal & External Versatility

R.S Urethane Blocking Primer is suitable for appropriately specified internal and external applications, providing installers with a versatile solution across residential, commercial and professional coating projects.

Its refined water-based formulation combines strong surface adhesion, improved opacity, high-build performance and dependable stain blocking within one professional primer.
