Dow Corning 791 Weatherproofing Silicone Sealant Brown 310ml is rated 4.7 out of 5 by 26.
Rated 5 out of 5 by from Sika I use Sika Seal for everything from window sealing, upvc jointing, roofing joint and general bonding and sealing. I have very specific requirements in regards to the components the product are made from; I have to supply this to the client for review prior to use. Sika (and Dow Corning) are the only products I trust and use, and most importantly, it works; far better than the low priced, low quality other products ‘out there’

Rated 5 out of 5 by from Dow791 This product is worth the money excellent adhesion and finish. I have re sealed around my upvc windows after picking out the old silicone. Only wish I had used this the first time Round.

Rated 1 out of 5 by from Beware!! - Not BROWN Disappointed - very - with this D&C product. Came with a brown snout. It even looked brown. But it dried like a Rich Tea biscuit. Spoilt the entire effect I was trying to achieve and I had to start over ... with Unibond. At least Unibond exterior sealant is actually BROWN out of the tube and when it dries. Moreover, this D&C product DOES NOT colour with either creoseal or woodstain - Unibond most definitely does. I would never use this product again. D&C internal sealant is fine, but, for me, their external stuff leaves MUCH to be desired.

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.
