epoxy grout with absorbent tiles

[Paslode]

Posted a thread a week ago about my bathroom,nonvitreius tiles and would they absorb water in the shower.have decided to use kerapoxy to hopefully ensure no water gets through the joints (hopefully!) Used ultracolor on the rest and it seemed to dry very very fast I'm guessing the tiles sucked it dry?Will the same happen with the epoxy ?many thanks alex

Ultracolour grout is very fast drying anyway.

Will the epoxy go fast too I know it's a nightmare normally but if it dries faster again then I am in trouble!

Kerapoxy isn't too bad to use, get the room cool ( not sweltering hot ) and warm up the Kerapoxy before mixing and you'll be fine if it's just the shower enclosure, pot life of about 45 minutes, just make sure you have a) plenty of clean water b) more clean water and c) more clean water, pads and sponges.

I have a 5kg tub do I split it down into smaller batches or do you think I could do the whole enclosure in one mix? About 8m2

I would say go for it in one, do two sides and check to see how the starting point looks, it really depends on a few things, how quick you are at application and temp of room, absorbancy etc, I was doing 5kg tubs in June, 5mm joints upside down, yep, on a ceiling and it was fine, as I say, warm up the Kerapoxy first by setting the tubs next to a heat source.

Good luck, and we like pictures we do.

Thanks for the advice,the tiles are 600x300 so there rant that many grout lines although the back wall has a vertical panel which is scored 4 times per tile ,I thought bearing in mind I haven't used it before of splitting in half and doing the two ends then the back wall in another mix?how many times do I go over it with a sponge and hot water?thanks again

Get yourself some emulsifying pads for the initial clean off, use in a circular motion, you'll see when doing it how it cleans any excess away from the joints then go over with your sponge and water, you go over it as many times as needed to clean off any haze and or grout, do NOT leave any grout behind, also it wouldn't hurt to tape off any surfaces that meet the grout lines, i.e painted walls, shower enclosure etc.

Make sure you have ALL your tools ready, before mixing, as for trying to split the tub into 2 mix's, I wouldn't, parts a and b are measured weights, get the mix wrong and your grout could set up way too quick.

Just a thought, here, what tiles are you using, I'm just thinking of possible staining ?

They are a ceramic Matt glazed tile which on the box says nonvitreous hence why I want to use epoxy so as to ensure water doesn't get through the joints, I also have a vertical feature on the back wall which are a sealed porcelain .thanks again for your help.
ps I have a epoxy
grout float 6 emulsifying pads and 5sponges ,enough?

 

[Alan.P]

Should be more than enough

grouting all done !the pads are awesome,have sponged it off a couple of times and can't see any grout on the tiles,do I now leave it overnight and buff tomorrow?mixed it probably 2hrs ago but the leftovers haven't set hard in the bucket?had visions of it going off like a bullet?.....

It should take more than a couple of sponges off to get clean, do not leave it over night no, how do the tiles feel if you run a finger over them ? sticky, hard to say without being there but I would give it a couple more cleans to be sure, like I said though, hard to say.

the tiles were clean not sticky at all,a bit concerned this morning that I can push my nail into the grout?..does it take 24hours or so to harden up?
