Also treat the inside of the tent for better protection. Old and worn cotton tents may need multiple treatments.
Safe for use on any cotton tent and in any location. Read the instructions on the packaging before use.
IMPREGNATING AGENT: Ultramar Canvas & Cotton Protector makes tents, trailer tents, army tents and awnings waterproof. Keeping the cloth well impregnated also provides additional protection against dirty water, green mildew and mould.
