Fosroc Nitobond Bonding Agent PVA, 25L, Used for Mortar, Render & Concrete Repairs

Fosroc Nitobond PVA is a white, water-based acrylic emulsion adhesive designed for interior and exterior bonding. It bonds a wide range of substrates such as wood, concrete, metal, plasterboard, and masonry. It performs well in damp or wet conditions and helps create a strong bond between old and new concrete surfaces, making it suitable for large-area applications.

Nitobond PVA adheres well to wood, concrete, brick, stone, plasterboard, metal, ceramic, glass, cementitious substrates, and gypsum. It is suitable for both interior and exterior use, including damp environments.

Key attributes include a white, water-based acrylic emulsion formulation with low VOC content, easy application, and low foaming characteristics. It contains additives such as UV stabilizers and corrosion protection to improve durability. It can be sprayed, brushed, or rolled and is suitable for bonding a range of substrates under interior or exterior conditions, including damp areas.

Common uses include bonding timber to concrete and other substrates, bonding plasterboard to masonry, and bonding various materials in damp or challenging environments. It is also used for large-area bonding such as walls, floors, and roofs where water resistance and durability are important.

Prepare the surface by cleaning, drying, and removing dust, grease, and loose particles. Apply the adhesive with a brush, roller, or sprayer to achieve a uniform coat. After application, allow the coating to reach a tacky state, then bring the substrates together and press firmly to ensure proper adhesion. Clean tools with water and avoid puddling of the adhesive.

Wear appropriate protective gear such as gloves and eye protection. Ensure good ventilation during use. Avoid ingestion and prolonged skin contact; wash hands after handling. The product is water-based and generally low-odor, but follow standard handling and storage guidelines for construction adhesives.

Store the unopened container in a cool, dry, well-ventilated area away from direct sunlight and extreme temperatures. Keep the container tightly closed when not in use. Respect the product’s storage recommendations to maintain performance and effectiveness.

Nitobond PVA 200L (the standard product) is the larger packaging intended for bigger projects, while the 20L version offers a smaller, more manageable quantity for smaller jobs or less frequent use. Both share the same adhesive formulation and performance characteristics. Compare here: https://fepy.com/product/fosroc-nitobond-pva-20l

The 50L packaging provides a mid-sized option between the 200L and 20L variants, offering a balance of volume and handling for medium-to-large projects. It uses the same adhesive formulation and bonding capabilities. Compare here: https://fepy.com/product/fosroc-nitobond-pva-50l

The 100L packaging is the largest option listed, ideal for continuous or multiple-project work, delivering the same performance characteristics and bonding capabilities as other sizes. Compare here: https://fepy.com/product/fosroc-nitobond-pva-100l

Fepy's standard return policy applies to this product. Returns are typically considered within the stated window subject to product condition and original packaging. For specifics, please refer to Fepy’s return policy terms.

If bonding fails, verify that both surfaces are clean, dry, and free from contaminants. Ensure an even, adequate coat is applied and that the substrates are joined while the adhesive is at the appropriate tack. Avoid applying in extreme temperatures or high humidity, and re-clean any surfaces if bonding does not take hold after initial bonding.
