Easy to apply - great product
Thank you so much for your fantastic review, Russ! Weāre delighted to hear FLEXICOAT was easy to apply and performed exactly as expected. Really appreciate your support!
Used on roof of new shed to keep it in good repair and then painted the walls in a well known garden product . Many many years later roof of shed wearing well but not walls. We bought a new shed and used FlexiCoat on walls and roof - boy does this do the job. We have since used it on fencing and this is still good even after putting a colour on top. I intend to do other work in the garden and have recently purchased more as sometimes not in stock . Excellent product and well worth the money and wouldn't buy anything else.
Hi Hazel,
What a fantastic reviewāthank you for taking the time to share your experience!
Itās brilliant to hear how well Flexicoat has performed over the years, especially compared to other products youāve used. The fact your original shed roof is still going strong after all that time really says it all
We love that youāve now used it on a new shed, fencing, and even overcoated it with colourāexactly what itās designed for: long-lasting protection with the flexibility to customise the finish.
Thanks as well for your continued support (and for coming back for more!). Weāre working hard to keep stock available, especially during busy garden seasons.

Easy to apply. Went much further than I expected. Even the brush cleaned up well afterwards. Only time will tell how good a job it does, but Iām pretty optimistic.
Hi Henry,
Thanks for your review!
Great to hear you found Flexicoat easy to apply and that it went further than expectedāthat coverage always surprises people in a good way And the easy clean-up is a nice bonus too.
Youāre absolutely rightātime is the real test, but once fully cured it forms a tough, flexible waterproof membrane thatās built to last. Sounds like youāve done everything right so far.
If you need any tips as it settles in or for future projects, just give us a shout.
