Yes, we advise impregnating your tent, boat cover or sun awning again after cleaning.
All cleaning agents damage the original impregnation. Therefore, we always recommend making the canvas watertight again after cleaning to protect it against mould, polluted water, bird droppings, etc.
Sprayhood & Tent Protector is a very strong impregnating agent. We developed it especially for use in our sail and tent cleaning facility. We use it with great success to impregnate tents, boat covers, sun canopies, catering umbrellas and tent awnings and to make them watertight.
Do you have a folding trailer tent or another kind of tent made of cotton canvas? Use Ultramar Canvas & Cotton Protector to make your cotton tent watertight.
