Grout Calculation Question - Tile Advice

[Wishiwasatoptiler]

Hi
I normally best guess my grout needs for a job, have this job the tiles are 25mm thick on average, average 320mm long x 220mm.
35 sq meter.
They want a 10mm joint as they tge tiles are bowed and and miss shapen.
Used an app to work out the grout needs and it comes up with 105kg.
Anyone got a sum i can use or know if this is right.
Cheer.

I've just tried it on a different grout calculator and comes up similar. Gotta be right

Some cost. Going to have to have a chat with them. They are adamant on a 10mm grout line. Be a small fortune.

I tried the ARDEX calculator on a job and had about 25% left over

Suppose it won't account for adhesive in the joint. Especially with thick stone if using a large notch there'll be a good few mm taken up with addy

I'll go for 75kg based on your experiance Julian if they stick with the joint size.

We've recently updated our grout calculator on our new website: weberjoint premium - https://www.uk.weber/weberjoint-premium

With the details your specified we'd say 100.67kg (of weberjoint premium). Different grouts have different densities (some are finer than others), but you can check the grout calculator on any of our grouts to find the quantity you'll need.

Hope this helps and let me know if you have any questions.

Rays point is a valid & if you do go old school & use the remaining mixture for dryers you will cut out the chance of dragging out the grout also
