Store rolls before use on end on a clean dry surface protected from the weather. Material should not be unrolled if the temperature is below 5°C as the adhesive will become brittle and may crack. Depending on application Sisalkraft 410 is laid over flat surfaces or fixed to studwork formwork or similar. It may be stapled nailed or fixed with self-adhesive tapes.

Sisalkraft 410 can be folded and cut easily using a knife or scissors. Edges should be overlapped by at least 100mm and if the installation is intended to be waterproof or water vapour-tight the seams should be welted or taped using a durable self-adhesive polymer tape.

Sisalkraft 410 is not intended as a primary weatherproofing layer and should be covered by other materials if wet or windy weather is expected.
