Dulux Heritage Tester is for use as a colour tester on interior walls and ceilings. This luxury washable matt emulsion is durable and water-based, offering effortless application and an irresistible soft-to-touch finish. Key Information Finish: Matt Coverage: n/a Drying time: Recoatable : 2-4 hours Coats: 2. Application is via brush, roller or spray. Stir thoroughly before use. Seal new or bare surfaces with a thinned first coat (up to 1 part clean water to 5 parts paint). The normal finishing process is 2 full coats, but on previously painted surfaces in good condition where similar colours are used, 1 coat may be sufficient. For best colour consistency, purchase sufficient tinted paint for each job at one time from the same source. Ensure surfaces to be painted are sound, clean and dry (new surfaces particularly must be fully dry). Do not use or store in extremes of temperature and protect from frost.
