Questions & Answers


Could this be used to paint over cracks in brickwork


It is more for use on a roof so could not be suitable for use on a vertical face.


i have painted my conservatively felt roof with acrypol + grey paint brought from this store will roofix 20/10 will be alright to paint on top


This would likely not really bond to the Acrypol so probably better doing another coat of Acrypol if it needed suring up.


Can this product be used on a vertical brick surface above flashing?


No this is not suitable on a completely vertical surface unfortunately.


Will it be ok to paint on top of existing fibreglass roof?


This would not bond to GRP I am afraid.


Will this be ok on my concrete garage roof?


Yes this will be suitable for application onto your garage.


Can I use this as a base for a green roof, line planters?


No - This is a solvent based product it will harm plant life.

A lot easier than trying to put new roofing felt on the shed and more effective as previously I think the leak was through some of the felt tack holes. Simple, easy and effective.

Easy to apply with a floor squeegee but you do need to remove all the pea shingle from a flat roof before applying otherwise you will need far more than the 5 ltr per 5 m² that is quoted. Worked very well on a pitched felted shed roof easliy filling all the imperfections.

A good product I have used it a lot over the years but I found this batch quite runny and I thought lacking fibres it was Rooffix M and not 20/10 as ordered. This is the reason I am only giving it four stars. I have used a similar product from a different manufacturer which was a better texture had more fibres and lasted longer.

We have only used this product in the last two days on our shed roof. Application reasonably straightforward. We're obviously Unable to comment on its efficacy as we haven’t had rain since applying the paint.
Sorry, there was a problem loading the reviews. Please try again.
