Is B.I.P. foam a cheap solution I see on You Tube people using some type of round foam and topping it with some sort of Mastic. I would appreciate some advice on what is the best products to use and if you can give the proper names of the products or is B.I.P. foam good enough. Thanks in advance for any information. To err is human but to really mess things up, you need a computer. Re: Brick Veneer Vertical Expansion Joints 2Apr 28, 2021 3:10 pm the foam you see is foam rod gap filler. The "mastic" youre refering to is usually a sikaflex sealant. Theres like 20 different varieties. I'm unsure if they're all fit for this purpose, but a large majority are (depending on what sort of material you're trying to adhere to). Sikaflex Pro and Sikafl;ex 11fc are likley to be what youre after. 11FC is more elastic AFAIK, its also more expensive and more annoying to work with in my experience. You use the foam rod as a backing so you dont waste 40x 600ml sausages trying to fill the whole brick wide gap.

Re: Brick Veneer Vertical Expansion Joints 4Apr 29, 2021 11:31 am dont think its nasty, but ive not seen it used to fill vertical expansion joints. But im not a builder. I cant imagine it provides a weatherproof seal in that set up. You could probably still use it as backing for the sikaflex.

Trust me, its in my sig. can’t tell from the photo, a tie down rod will be 12mm, is it a steel beam? he should be able to work it out 1 5576 5 11164 Brass fly wire, you will need to cut it, shape it and jam it into brick slots 1 8054 |
