Washed out by most

The first parquet varnishes were based on solvents and due to allergic reactions were not popular. Therefore, now the market is filled with water -based varnishes. But among them there are those that include polyurethane. Such compounds are harmless to humans, are not washed out by most solvents, but are quite capable of ruining the parquet. The most environmentally friendly are varnishes based on acrylic resin. Their only minus lies in short -lived, so the parquet processing will have to be repeated from time to time.
