Rated 5 out of 5 by from Reliable Product Costs a little more than other outdoor sealants but it's worth every penny for peace of mind. This is totally weatherproof, it's very smooth and gives a great finish, it'll give you peace of mind for years to come, highly recommended.

Rated 5 out of 5 by from Great Sealant Used on old French doors to seal around the panes. Worked well and is hardly noticeable due to the colour. Easy to use, and non/little odour which isn't always the case

Rated 5 out of 5 by from Excellent frame sealant Have used a more expensive product for sealing around external window frames a few times and having now used this product I will be using again, I would actually say it it easier to use and of a better consistency than the more expensive brand, highly recommend this product!!

Is this paintable? I was going to use it around windows before painting. Thanks

Asked by: Matticusuk
Dow Corning 791 is a silicone and as such will not accept a paint coating. You could try to match the colour using either Dow Corning 791 or 796, or you could use Geocel theWorks Sealant and Adhesive. theWorks is paintable provided that you use a water based paint.
