The 30m² Waterproofing Box is our most complete DIY kit, built for extensive waterproofing projects and larger roof sections. With 10 litres of S400 coating, cleaner, tape and a full set of application tools, it has everything you need for a serious job — no half-measures, no extra trips to the store.

Why Choose the 30m² Box?
This is the kit for the job you can't afford to run short on. Ten litres of our high-performance S400 coating, plus Muckoff cleaner for the prep, waterproof tape for the joints, and a complete tool set including 230mm roller sleeves and a tray — enough to work efficiently across a large area without stopping. Clean, tape, coat. Everything's in the box.
We also offer 10m² and 20m² kits for smaller projects, and the S400 coating on its own in 4L, 10L and 15L — plus colour matching to almost any standard roof colour. Get in touch and we'll help you find the right fit.
