    Hi,

    I have got a granite counter top to fit and was going to use CT1 to bond it to units. However, after watching some reviews I am not sure whether its the best for the given task.

    I was lead to believe by all the hype that CT1 was some revolutionary material.

    I have a lot of experience in the marine industry and always used polyurethane adhesive for bonding but was hoping this MS polymer stuff might have given an advantage.

    I would be grateful for any views or recommendations.

    Thanks

    Ct1 is excellent, why do you think otherwise? With the weight of the granite alone I would think clear silicone would be more than adequate, especially if sealing around the edges and covering with a matching upstand.

    Could bed granite on units with CT1, & use a silicone if sealing around the edges and covering with a matching upstand.

    Bedding a top of that weight ....you could use any silicone.
    Upstands or beads that show....well CT1 performs very well...in particular the Crystal Clear version.

    CT1 did not seem to yellow when I used it...but another clear brand has very quickly..on the same type Resopal worktops and upstands .
    Just an observation.

    MS polymer if any kind of damp, Stixall is Ms Polymer. Less elongation, stretch with MS polymer. Polyurethane more stretch, more sensitive to damp.
