Flag Roofix 20/10 Roof Repair Waterproofing Paint has been specifically developed to provide instant waterproofing for leaking roofs.

It is an all-weather product, which can be applied even in damp conditions. Roofix 20/10 can be used to repair specific areas that are leaking or totally waterproof an entire roof.

This product is multi-purpose and can be utilised on a wide variety of problem areas.

Made in the UK, it is a single pack elastomeric acrylic based (non bitumastic) compound with built in Draylon fibre reinforcement, which provides excellent flexibility and durability.

Roofix 20/10 does not require special primers and can provide long term protection in excess of 10 years.

Before application, the surface should be stable, firm, dry and free of dust, sand, loose old paint, dirt, grease and oil. It should not be applied in the rain or when rain is likely. Pooled water must be removed before application.

Touch dry in 16 hours, depending on conditions (ideally 20°C). Curing takes between two to three days.

Theoretical spreading rate is 1 sq. metre per litre.

Customer Product Reviews

  • Roof repair paint

    I didn't think this would work but I needed to try a quick fix as I couldn't afford to replace the leaky roof over the kitchen extension. It's quite thick going on and when it rained the next day the roof didn't leak! For the price compared to a new roof it was good value; even if it only lasts a few years.

  • waterproof roof paint

    I used this on the garage roof when it started leaking over winter. Dried quickly and stopped the leak. Wish it came in a smaller tin as I only needed to do one corner where the leak was.

  • Roof repair

    Needed to waterproof my extension roof with the winter we have been having. This stuff really did a good job.

  • Garage Roof

    My garage had an annoying leak for some time now, but the roof repair waterproofing paint sealed it up brilliantly.

  • Roofix Paint

    Highly recommend. Used once and the seal is still going strong despite all the rain we have had over the last few weeks. Great stuff.

  • Good thick stuff!

    Good thick stuff, does what it says on the tin.
