Questions & Answers


Would this product repair cracks in old asbestos sheets?


You would be better off using something like Acrypol for repairing cracks - for any large cracks also use the Acrypol Scrim (linked below).



will this product take light foot traffic?


Once fully cured this could take light foot traffic.


I have 215m2 of on old bitumen flat roof the roof is solid. Can I clean the roof and use this straight on top of the bitumen and mineral edges.


It would need to be fully cleaned first and completely dry before application.

If you wanted to email some project details to sales@roofingsuperstore.co.uk we can always check with the manufacturers for you if a flood coat would be needed.


I have 2 concrete canapies that are 50+ years old and need refurbishing. They can't be replaced and I don't want to go down the felt and hot bitumen route. I think this product will do the job, my question is, because of the age of the concrete would I be best to apply a primer?


Best to apply a floodcoat first before applying the liquid rubber, please find this linked below.



I have a flat roof above my garage which also doubles as a rarely used balcony . When cured can the eco proof 20 product take light foot traffic?


This could take light/infrequent foot traffic but if a balcony we would advise to have something else to protect the suface after laying this.


I have 2 concrete canopies that are over 50yrs old and need refurbishing, can I apply this direct to them without a primer? I don't want to go through the nonsense of felt and bitumen.


If the concrete is porous then we would advise to apply a flood coat first before the liquid rubber, please find this product linked below.


Does this require a primer?


It depends on the roof surface it is being applied to, if you send your enquiry to us sales@roofingsuperstore.co.uk we can check with the suppliers for you.


I have 30 m2 to cover. How many litres would you recommend please.


The coverage is a 2 coat application at a rate of 1ltr per sq/m per coat, so we would recommend getting 60 ltrs to allow for two coats on your 30m² roof.

So far so good, can be a bit messy to apply. Once applied becomes hard. Great for chimneys and roofs, also works well with cracks.
Sorry, there was a problem loading the reviews. Please try again.
