Everbuild 501 Universal P.V.A. Bond Yellow 500ml PVA05L | Multi Purpose Adhesive - Sealent and Admixture | Bonds to Most Building Materials | Ideal as a Primer on Porous Surfaces | Fully Conforms to BS5270

Everbuild 501 Universal PVA Bond 500ml is a high-performance multi-purpose product designed to meet the needs of both professional builders and DIY users. This versatile solution functions as a powerful adhesive, sealant, primer and admixture, making it a must-have in any toolkit. Engineered to adhere to most common building materials, this product is suitable for various internal applications and is ideal for use on porous surfaces. It fully conforms to BS5270 standards, ensuring reliable bond strength and safety in use. This medium viscosity bonding agent is a polyvinyl alcohol stabilised, externally plasticised, vinyl acetate homopolymer. Its advanced formula contains no harmful phthalates, making it safe to use in a wide range of environments. The yellow colour helps users easily identify treated surfaces during application. Everbuild 501 Universal PVA Bond is suitable for general-purpose adhesion of wood, cork, paper and textiles. It is also effective as an internal filler when combined with materials like wood shavings or plaster, offering a practical solution for patching and repairs. One of the key benefits of Everbuild 501 Universal PVA Bond is its use as an admixture for mortar, screeds and renders. When added to these mixes, it enhances flexibility in sand cement products, improves frost resistance and reduces the risk of salt permeation. These enhancements contribute to long-term durability and better performance in varying conditions. It also allows mixes to be applied in thinner sections without compromising structural integrity. In construction and renovation projects, surface preparation is critical for long-lasting results. This PVA bond acts as a reliable primer and sealer, especially on unsound or porous surfaces prior to plastering or painting. It reduces surface porosity of mortar and plaster and improves adhesion to difficult substrates such as dense concrete, steel, glass and tiles. Whether you are sealing flaky paintwork, bonding screeds or preparing walls for tiling, this product ensures a solid and secure finish. Another practical use of this product is its effectiveness in general dust sealing. On flaky walls or paintwork, Everbuild 501 Universal PVA Bond creates a sealed layer that stabilises the surface for follow-up decoration or treatment. Its multi-use functionality also extends to tiling jobs, where it acts as a primer and sealer to help secure tile adhesives more effectively. This all-in-one solution provides numerous performance benefits. It significantly reduces surface dusting on concrete, lowers the water to cement ratio for equivalent workability and helps reduce surface porosity in both plaster and mortar. These enhancements make surfaces more robust and resistant to environmental wear and tear. The product also improves the overall workability of construction mixes, saving time and effort during application. Everbuild 501 Universal PVA Bond has been developed with the specific requirements of the building industry. It offers greatly improved adhesion on a wide variety of materials and surfaces. This makes it particularly useful for renovation tasks that involve bonding new screeds or renders to existing materials. It creates a strong and long-lasting bond between layers, which is essential for durable repairs and modifications. The safe-to-use formula ensures peace of mind during application. It meets the stringent requirements of BS5270 standards, confirming that it delivers dependable bonding strength. In addition to its excellent technical performance, its user-friendly nature makes it accessible to tradespeople and DIY users alike.
