What can you expect from a linseed oil paint on interior surfaces? Interior painted surfaces are not degraded by sunlight, but by mechanical abrasion and cleaning with strong chemical products. Newly painted surfaces take several weeks to harden. Therefore, avoid placing heavy loads on these surfaces, and clean carefully immediately after painting. If you have a freshly painted floor, you should avoid walking on it with shoes for the first few weeks.
When the linseed oil paint surface has hardened, clean it carefully with gentle, pH-neutral products that will not damage the painted surface. Ordinary dishwashing liquid works well. Another good choice is to use the product Fulgentin, which not only cleans the surface of dirt and grease but also imparts new luster.
