6 steps to a waterproof solution

Identify the problem

A leak is often not where you think it is. A wet spot in your wall can be rising damp, but also pouring rain. Read the tips in this guide. Follow the step-by-step guide.

Can I solve it myself?

A problem is often simple. A small leak or slightly damp basement walls. But it may also conceal an underlying cause. Don't take any chances if you think an application is beyond your ability. When in doubt, ask a professional for advice ... Safety first!

Perfect execution

Have you read the manual? Then you know exactly what to do. Pay close attention to minimum and maximum processing times and temperatures.

Roofs are for years exposed to wind and weather, high and low temperatures and especially the effects of destructive UV radiation. This means that roofing and EPDM can become dull and brittle over time, tapes and sealants can become detached or drop down, and leaks can occur.

Used correctly, WP7 roof products are fully resistant to damage from temperature, water and UV. In addition, they are easy to use and you can almost always be sure of good results!
