Rated 4 out of 5 by from Great but wear good gloves! Good value as always from screwfix. Product is good and easy to apply but be aware you need to ensure you don't get it on anything that you didn't plan on as it won't come off!!! I used a large brush to apply with the intention of disposing of afterwards as cleaning would be a nightmare! So great product but plan before use

Rated 1 out of 5 by from Didn’t work for me Bought to fix new felt to an older felt covering on a flat concrete roof. Application was on a warm day although not near the max temp as noted in the instructions. Went on like paint with a brush (good - as per instructions) then had to leave for between 15 and 60 mins in order for it to become tacky….mine became tacky after around 1-2mins….so left for another 5mins only to find it had ‘dried’. Repeated but left for around 15mins with same result - dried. Had no option but to stick felt down after ~2mins. Applied 4m and 3m lengths of full width felt (1m) plus some odd 150mm strips……then left alone for ~24hrs. Before returning I phoned Bostic tech department and spoke to a chap who, although pleasant, tended to simply repeat what was written on the instructions plus ‘hinting’ that warmer weather ‘could’ reduce the tacky time. Didn’t really help or offer any useful suggestions/explanations. On return to the site I then found that I could simply peel off the strips (what a mess) and although the full width felt did stick in places, there are significant areas where it obviously hasn’t, especially the edges which, if I wanted to, I could peel/lift away. I’m now hurriedly trying to source a grab adhesive suitable for felt in order to stick down the edges…..I’m having to simply hope that, over time, the ‘loose’ sections WILL, at some point, settle down and adhere. Somewhat difficult to return a 1/3 tin to screwfix for a refund??? Will definitely NOT be purchasing this one again and, in my opinion, cannot recommend it.

I am using bitumat roof shingles on a summer house. The installation guide suggests that I use an underlay as well. I am thinking Protect A1 roofing underlay, fixed with Bituminous felt adhesive for both underlay and shingles. Is this OK?

Asked by: KEDA
The Bostik Feltfix Bituminous Roof Felt Adhesive Black is a solvent based bitumen felt adhesive that is designed for bonding bitumen based roof felt to various roof materials including asphalt, existing roof felt and concrete. However, the product is not suitable for bonding roof felt to a wooden roof, and is not suitable for use with the Project A1 roofing underlay ( which is a plastic polypropylene type material ), and it is also is not specified for bonding roof shingles in general. Consequently, in consideration of the above, the product is not recommended for use in this case.

Does it set?

when applied to angled surfaces - ie to seal gaps - 5-10mm, does the tar 'set' after applied, or will it 'slump' during warm weather?
Asked by: bobrg
The Bostik Cementone Bituminous Roof Felt Adhesive Black is a solvent based bitumen felt adhesive that is primarily designed for bonding bitumen based roof felt to various substrates including asphalt, existing roof felt and concrete, and it can also be used as a gritting adhesive for bitumen roofs, as well as be used to seal laps on roof felt. As such, the product is not a tar type of product as it is a bitumen type of product, Once applied the product dries by the evaporation of the solvent out of it leaving the remaining bitumen component in situ. Once dried it has an in service temperature resistance of - 20 ° C to + 70 ° C when used on a slope of less than 10 °. The product will harden and soften depending on the weather temperatures that it is subject to within this range.

Felt adhesive on bitumen painted wood

Looking to protect partially buried oak sleepers. I will prime and paint the buried wood with BITUMINOUS PAINT, maybe belt and braces but can I use roof repair compound to stick roofing felt over the bitumen painted surface.
