Can we apply a second layer of DuroGrit for an even better protection or more intense colour?

DuroGrit is a one layer product. When two or more coats are applied, the UV protection will be improved but the system will also become more film-forming. This might result in typical problems of film-forming systems such as flaking/peeling. In addition, the curing time will also be prolonged. However, in exceptional cases, e.g. very grey/weathered wood, a second layer might be necessary for aesthetic reasons. The first layer will act as a primer, but due to the high and inequal absorption of the wood, a second layer will provide a more uniform colour result. In these cases we also advise diluting the DuroGrit with 20% of water. The risk of building up a thick film-forming layer here is low, because a lot of the product is absorbed into the weathered wood.
