My biggest tiling job yet - Tile Advice

[J Sid]

Standard gypsol classic has compressive strength of minimum C25 and Kingspan has a compressive strength of 150kPa. If the Aston Martin weighs 2tonnes that's 2000kg so 500kg on each wheel. That will exert 0.5kN force. So it is perfectly strong enough. Done loads of garages and car showrooms. Never had an issue

But because they are pneumatic tyres equally space on a solid chassis it acts as a uniformly distributed load so the actual down force is much less than would be expected. Lost count of the number of garages I've done in flowing screed over the years. Never had an issue with weights. I think the heaviest I know of is a hummer. Unless a light aircraft weighs more... done quite a few light aircraft hangars as well.

Ajax. I was starting to get disheartened about this job until you came along. I can't really get away from doing this job as the guy is one of my bosses. I feel a bit more comfortable after your comments but what about expansion joints in the tiles. Could I get away with tiling it in four sections and would I need a solid bed of adhesive or maybe use a wall trowel notched to10mm deep. Cheers for your input. In fact thanks to everyone who's commented.

Aston's are front end heavy so it'd be more like .65 on the front and .35 on the rear maybe lol

A 10mm trowel Carl, is the last thing you want to be using.

Well give me something positive then please mate.

I really don't want you to make a balls of this job Carl, that's all, don't under estimate it. Personally with a 900x900, the best way to get good adhesive coverage it to comb the floor, and the back of the tile in the same direction. If you did that with a 10mm trowel you would probably be alright.

Flow screed, is this anhydrite?

Thanks. Same direction? The floor is bang on flat. Keep asking about expansion joints too. Can you tell me if I need them and if so could I separate the floor into 4 sections?

I've no idea what it's called Pete. I wasn't around when the contractors laid it but I'm told it dries like steel.

I've don't know Pete.

Carl, you shouldn't be taking on this job, get a pro in.

 

[J Sid]

first job before you do anything is to get the floor check for how dry it is. It needs testing, some adhesive companies will do this for you Bal and Tilemaster I believe, others may know more.
I believe they with also give you a written spec

It's been laid since the end of last November so I would assume 50mm drying at 1mm per day it would be more than dry enough. Roughly twice as long as recommended. I will make the suggestion tomorrow when I get to work if you think it should still be checked, but I think they may be expecting me to start it. Again, will it be OK to split it into 4 sections with expansion joints?

You need to know mate, if it is then you'll need to sand any remaining laitance off the top, moisture test to be on the safe side then use a gypsum based adhesive like anhyfix to fix the tiles
