WRAS Approval for Potable Water Tank Paint – Why It Matters
If you're specifying coatings for potable water systems, WRAS approval isn’t optional – it’s required. A WRAS approved paint has been tested to ensure it won’t leach harmful substances or affect the taste, smell or safety of drinking water. The Water Regulations Advisory Scheme checks each product formulation, ensuring quality control and traceability. Under WRAS approval listings, paints and coatings in the category "Coatings, Paints & Linings" must pass detailed testing. Using WRAS approved products gives you peace of mind, whether you're coating pipes, tanks, fittings or valves.
Types of Coatings Available – From Epoxy to Solvent-Free Polyurethane Coating for Potable Water Storage
At Promain, we offer a wide selection of potable paints coatings WRAS approved for both industrial and domestic use. From high-build epoxy systems like Hempel Hempadur 35560 WRAS Approved to solvent-free polyurethane coating options like Axalta Acothane Mastic Standard Grade, every product is formulated for safe drinking water contact. Some are branded as WRAS approved epoxy paint, others as food-grade water tank paint – the difference often lies in use case and surface type. Whether you're lining steel tanks, GRP vessels, or concrete reservoirs, the right mix of coating type, surface prep and cure time is key.
Hygiene Paint & Antibacterial Paint – Why Potable Means Clean in Food and Beverage Water Systems
Potable paints coatings WRAS approved aren’t just about safety in water contact – they also support hygiene in food-grade applications. In areas where water feeds into food processing or beverage systems, hygiene standards are even stricter. Antibacterial paint and hygiene paint options help reduce microbial growth, especially in warmer temperature zones or where regular cleaning is needed. These coatings are ideal for environments where hygiene and potable standards cross over, helping you meet audit requirements while keeping tanks and pipes safe and compliant.
Where to Use Potable Water Tank Paint UK Specification – Typical Applications
Potable water tank paint is needed across a wide range of installations. This includes new builds and refurbishments for water tanks, booster sets, distribution pipework, feed systems and potable supply lines. WRAS approved paint systems are required for any surface that comes into contact with drinking water – from steel pipe interiors to concrete tank linings. Products like Jotun Tankguard DW, Axalta Acothane Mastic Standard Grade, Fosroc Nitocote EP405, and Sika Sikadur 31 DW are all approved, long-lasting and suitable for potable water tank coating jobs across the UK.
Potable Paints & Coatings WRAS Approved – What Affects Cost and Price?
We often get asked about potable paints coatings WRAS approved cost and price per job. Prices vary depending on factors like substrate (steel, concrete or GRP), the type of product (e.g. solvent free or high-performance epoxy), the required film thickness, and the surface preparation needed. For example, Acothane DW is a premium polyurethane coating that may cost more upfront, but offers excellent longevity and low maintenance. Don't just focus on price – the full system life, cure time, resistance to corrosion and ease of application should also be part of your comparison.
How to Choose the Right WRAS Approved Paint System for Tank Lining
Choosing the correct WRAS approved paint system starts with matching the coating to your substrate – whether that’s GRP, steel, or concrete. Then you need to factor in application method (brush, spray, roller), curing temperature, hygiene needs and whether you're coating pipes, tanks or mixing vessels. Cure times, film thickness and environmental conditions also matter. Our technical team at Promain can help match you to the right system, with data sheets and WRAS approval certificates available on all major products.
Food-Grade Water Tank Paint – Extra Protection for Sensitive Environments
In food, beverage or pharmaceutical environments, food-grade water tank paint offers more than just potable approval – it also makes cleaning easier and supports bacterial resistance. These paints are often WRAS or DWI approved, suitable for areas where drinking water touches surfaces used in production. They are ideal for breweries, dairies, bottling plants and any other facility needing clean water contact. Available in standard finishes like light grey, cream, or blue, these coatings make hygiene inspection and quality control simpler.
WRAS Approved Potable Paints Coatings – Long-Term Compliance and Protection
WRAS approved coatings protect more than just water – they also protect your assets, reputation and regulatory standing. Whether you’re applying a coat to a new tank or refurbishing an older system, correct certification matters. WRAS approved materials ensure compliance from the stopcock to the pipe end. And by using high-quality paints and coatings, you’ll reduce corrosion, extend the lifespan of assets and avoid contamination issues that could lead to fines or rework.
