Which trowel

[JohnnyB]

Hi
I am shortly going to tile a double garage floor with porcelain tiles, around 360mm square, the customer has a 4x4 car and so it will be taking some weight. The floor area is around 40 sq mts, and this is my first garage floor, so I was wondering which kind of trowel is best to use, square or round notch?

Thanks

Use a trowel that will give 100% coverage. A good large square noth can sometimes only give 80% or less, so a large round notch would be better. There's a 25mm half moon trowel or a thick-bed solid-bed trowel that's made for the job.

you will also need to use a good adhesive like bal motorbond on that floor because of the weight issues pricey though about £30 a bag

I would use the Karl Dahm - special trowell - deep. 100% coverage guaranteed
