This Dulux Heritage Tester in Boathouse Blue provides a luxurious washable matt emulsion finish, perfect for sampling colours on interior walls and ceilings before committing to a larger purchase. It is durable, water-based, and offers effortless application with a soft-to-the-touch feel. The paint is designed to keep your home looking fresh and is wipeable. Always stir thoroughly before use and ensure surfaces are sound, clean, and dry. For best colour consistency, purchase sufficient tinted paint for each job at one time from the same source. Do not use or store in extremes of temperature and protect from frost. Not suitable for use as a touch-up paint. Application is via brush, roller, or spray. Seal new or bare surfaces with a thinned first coat. The normal finishing process is 2 full coats, but 1 coat may suffice on previously painted surfaces in good condition with similar colours. Drying time is 2-4 hours for recoating.
