leaking rooflights / hatches quick repair

[n brown]

as the previous owner had glued my daughter's rooflight with sikaflex, when it started leaking , a lot , i found i couldn't remove it without breaking it. so i washed and dried off the existing mastic and covered it with this stuff, applied with a spatula , 6 months later , dry as a bone . if you feel you want to do it properly at a later stage , this stuff can be removed with white spirit. 145 Butyl Rubber Sealant - 310ml 145GY | Zoro UK

Butyl rubber is an excellent sealant Nigel, but I would suggest that it is not easy to work with if you don't know what you are doing.

It is very messy and hard to remove once applied.

hi Rob , must say if you're,looking for a neat job, it's not going to happen , but i used to get all my windows, hatches and guttering etc off scrap buses and vans , and butyl was the mastic of choice . scrape off the worst and wash with plenty of white spirit and it thinned down enough to remove with cloths

As a boat owner I got the habit of of using marine sealant and have used this stuff on my windows and roof lights with great success so far.

i've fitted dozens of vans , and never had any luck with silicone . biggest problem is , if it goes wrong nothing else sticks to it
great for fixing tiles though !
