Great value To use their own phrase,does exactly what it says on the tin... 21 Mar 2015
roof seal what a great product , I am a painter of 30 years experience and always used bitumen. but tried roof seal instead for cracked roofing felt. it worked great went on like emulsion and no mess . superb! 14 Mar 2015
Does the job Easy to apply and clean up. Great improvement to leaking garage roof which is now waterproof and looks good. 24 Oct 2014
Great product - easy to apply A water based product made it very easy to apply and meant absolutely no strong chemical fumes were present. It is a mid/dark grey when wet, but drys a much darker colour grey, almost black. This clever colour change indicates clearly when it has dried. Used for applying to a shed roof where the existing felt had cracked and some moisture was beginning to seep through. Coverage was exactly as stated on the tin, although it might vary from quoted amount depending on absorbency of surface. It dried in around 6 hours and withstood heavy rain 10 hours after application. I now much prefer to use this to traditional bitumen based products. Cleaning up brushes afterwards was easy using soapy water. 22 Oct 2014
