HB42 has launched its new Ultimate Waterproofer. Available in trade-sized 6kg tubs, this waterproof membrane is highly elastic, self-levelling, non-brittle, and has gap filling properties suitable for all kinds of repairs and seals both internally and externally.

You can apply the HB42 Ultimate Waterproofer straight from the tub with a brush, trowel, or squeegee – there is no need for mixing. It’s ready to use, easily applied, fast curing and immediately waterproof. It can also be applied in dry or damp conditions and on damp surfaces too, making it ideal for repairs where leaks or seals have ruptured.
