Good product for water proofing
Tried this product on the shed and was impressed it prevent water ingres where we had bitumen flashband applied, this year we used it again and also on the house. It needs a good stir as it can give the impression its thin until stired. All the bostik products are top quality i have never been dissapointed with anything in that brand.
