Repair and gap filling sealants, by design, are ultra-handy for project managers and builders across the UK. With excellent precision, sealants can be applied to a wide range of substrates and surfaces to fix minor defaults, cracks, gaps and holes, or act as part of a major renovation and repair project toward the finishing stages of flooring, walls and ceilings.
Designed for internal and external use, always refer to product datasheets for product suitability, to ensure that you achieve the correct level of waterproofing, flexibility, colour, UV protection, and more, when applying sealants.
Most sealants available to buy today are Rawlins Paints come in packs, and not singular products. This is typically reflective in the pricing, where bulk buying sealants works out to be more cost effective for professionals.

Sealants are typically used to stop corrosion from liquids and fluids penetrating into and damaging gaps or cracks in the surfaces or joints of building materials. On building sites, where there are large volumes of tools and equipment generating dust and small soil particles, sealants are often synonymous with caulking, to block these particles, along with sound and heat transmission. Dependant on the environment, the user may need to use weak, strong, flexible or rigid sealants to best protect surfaces and substrates, along with using a sealant with or without additional adhesive qualities. Sealants used on major renovation and repair sites, including new construction, may be referred to as adhesive sealants or structural sealants.
The waterproofing capacities of sealants, along with their restricting sound, light, heat, dust, and more from passing through joints in a structure or substrate, means they are used for stopping these elements getting into or getting out of sealed areas. For example, sealants used on pipework or industrial guttering would stop leaks. Seals on water tanks must keep the fluids in, and remove risk of contamination from exposure to other elements, toxins, chemicals, or heat from external sources.
To summarise, sealants stop the spread of the following into or out of cracks and joints:
Sealants - dependant on the products' specified recommended usage - can be used on and within:
Industrial sealants available at Rawlins Paints from manufacturers including Remmers and Sika, can provide:
