Sanitary Silicone

[whyme!]

Will this be ok to use outdoors to seal between concrete garage sections (joins)

Is the garage already built or are you building/sealing joints as you go?

I'd probably look at a frame sealant or something like this http://www.screwfix.com/p/dow-corning-791-anthracite-weatherproof-silicone-sealant-310ml/44836

 

[whyme!]

it is to seal the joints after construction. was hoping for a cheaper way as i imaging it will take a fair few tubes
But then again using the wrong one will cost more in the long run

How many joints to seal, what length each and how wide a bead required?

 

[whyme!]

3mm 6ft 6 a panel about 25 panels( of top of head)

I've just looked at a tube of frame fix in my van, it says coverage 6mm bead - approx 11 linear metres.

So, 6'6" is about 2m therefore, one tube should do 5 panels easily.

25 panels x 6 tubes (to be on the top side) of Dow Corning or similar works out at about £25.00 in product, plus a few quid for an applicator gun....1/2 a day to do the job & 30 quid'ish in materials....
