The Brew Cabin

I`ve Just had my perfecta slabs delivered and i think i know what im doing....Geofix grout sounds easy and quick but what colour do i use? you cant see a sample!
slab are 450/450 natural about 14 sq meters, i`m thinking of 5-7mm gaps and id like to finish grout close to the suface2-3mm. any tips?

With the smooth ground Perfecta flags, I like to use a dry grout, but you can use Geo-Fix if you wish (and you have money to burn!!).

The standard colour (a sort of buff) will be fine, as the joints should only be 5mm wide and, in 3 or 4 months time, the surface will have discoloured and become covered in detritus, so you'd have no idea which colour (from the vast choice of 2) was used originally.

Thanks for that Tony, this site is worth its weight in Geofix...5mm does look better as you say,but what dry mix would you grout em with? and is the patchy dark and light areas normal? is this just residual wetness, will they dry out to an even colour.

Use a 3:1 dry mix, preferably silver sand, if you can get it at a reasonable price, but normal building sand is just as good.

Patchy dark/light areas? That doesn't sound right - do you have a photo or a fuller description?
