Ceresit Universal Refill

I bought the Entwesserungsbeutel for my very wet basement. You'd have to have a lot of patience to have this granulate shows its effect. For campers, there may well be sufficient, but for a wet basement, this product is not recommended. I then bought me an electric dehumidifier. The result is verblüfent. In a few weeks I was able to reduce the humidity from 93% to 65%.
