Leaks and Damp

Water will find its way through poorly sealed joints, seams and holes, including screw holes causing damp, rot and corrosion problems. The front and rear of caravans, motor homes and trailers can be particularly vulnerable because of wind pressure effects during travelling and rain discharge when static.

Non-setting mastics such as butyls can be squeezed out of joints or seams by movement or tightening down screws. Some are not resistant to acid rain and can break down after a few year’s service. Joints and seams should be inspected every few years. Look for tell-tale signs such as rust stains and streaks.


Sikaflex-512 Caravan Sealant is a strong elastic adhesive that bonds and seals in one operation. It is purpose-designed for building and repairing caravans, motor homes and trailers and does not suffer from the problems of traditional mastics. Correctly installed, it will provide many years of leak-free, and trouble-free service.
