Mixing ratios for one tile

[RDTiling]

Hi all.

i hope this doesn't come across as too silly a question, but here goes. (This is only my fourth tiling job, so go easy on me!)

i've been asked to replace one tile on a bathroom floor that has cracked size is 30 x 30 (this is the first time I've been asked to replace a single tile). I have pointed out that this is not a permanent fix and it may happen again, however they don't want to replace the whole floor at the moment, so this is just to make it look better.

Does anyone know roughly the volume of water required for this one tile. I've got about a quarter bag of weber rapid set SPF left from a previous job, which I hope should be enough?! I usually end up mixing way more than I need, and trying to avoid buying a fresh bag.

Thanks all.

Do it by eye,try 3 or 4 bucket trowels worth of powder and mix in water till you get the creamy consistency you desire.:smilewinkgrin:

Weber is approx 250ml of water per KG of adhesive, that will be enough to do one tile.

Thanks to you both Judge and Bri. I've tried trawling the www to find the answer, but no luck so decided to bite the bullet and ask.

Thanks again,
Rich

According to the data sheet based on a 6mm bed you need 810g of powder and 210g of water....

or you could mix it up by eye in a small bowl and chuck away what you don't use...

I don't use ratios just mix by eye/feel of the mix....

I thought that's what everyone did, I've never mixed it to a set ratio before

I seem to over estimate the water needed - was tiling a splash back the other week. The area to tile was only about 1.6m2 and I had enough rapid set mixed to do that area about 4 times over! I guess I'll get better at judging this with the more jobs I do.

I've been tiling for about 12 years and I still mix up way too much grout nearly every time!!

Add powder to water rather than water to powder.
All bags will at least have an approximate mix ratio on the bag. I have a measuring jug on the van, mainly fir SLC mixing. As the guys I do addy by eye and feel.
Might be handy for you to get one until you get used to your ratios. I've also got a small set of luggage scales. Nowt wrong eith being maticulous

Good advice Ali - My next tiling tool purchase is a measuring jug!


i do put the water in the bucket first - just seem to put too much in!

Likewise, only ever use it for SLC & large expanses of grouting mosaic when I mix a whole bag of grout.

If you have a CTD near you they're selling medium size weber pails. Only £2ish. I got a couple of them. Handy for when, like geoff, you mix a whole bag of grout, measuring out your water and weighing part bags of addy.
But a jugs handy too. Somewhere like wilkinsons? Or other cheap, highstreet, I sell everything shop. Got the luggage scales from one too. Couple of quid each.

Having mixed or had mixed for me in 30 years lots of powder up to 200 tons plus a year in my time no i have never looked at ratios lol

Went round yesterday to replace the one cracked tile, the customer then asked me if I could re grout the floor as most of the grout was cracked/crumbling, and would make the grout colour the same. I thought 'bonus' some extra ££'s!

After removing the cracked tile, I raked out the grout from around the next tile and the tile just lifted off, the next tile did the same, so I stopped there and let the customer know the problem.

The bathroom floor has been over boarded with ply, which after removing the tile and adhesive looks sound, although after lifting almost 1m in length of tiles I didn't see a single screw going into the floor boards. I set up my laser level and walked over the floor and there was little or no movement.

Current floor has been down about 10 years and the grout has been cracked for 'quite a while'. I can only assume that water, steam etc has got into the cracks and started to work the adhesive loose.

Customer asked me to just refit the three tiles and grout around them. They have conceded they will need to look into replacing the floor soon, so the have my number for when the time comes.

After all that, your advice re amount of water was spot on and there was very little wastage, so thank you again to all who replied.

I've got a measuring jug now and is sitting in the flexi bucket, that is currently being using as a toolbox, in the back of the van.
