Quality silicone Good quality Low Modulus silicone that performs well. The Low Modulus is always more expensive but has greater flexibility so that's what I needed 18 Mar 2015
Good stuff have used nearly 30 tubes in the past few weeks Easy to use, excellent seal if used correctly. Check the date on the tubes sometimes they can be old. 20 Feb 2015
works great used this to seal a bath between tiles always leaked slightly but this sorted it completely brill 20 Feb 2015
Excellent Service I rate Dow Corning as the best on the market. It retains its colour sheen durability for the duration of its life with excellent adhesion and sealing properties also. 2 Dec 2014
