Regrout

[Ian]

Has anyone ever been brave enough to attempt a regrout on a floor with electric heating under it? If so, how did you go about it? I understand from the client that the mat wasn't SLC'd before tiling, so that adds to the issue. Any thoughts? Thanks, Bri.

Not me but if you think about it the old grout needs to be removed or at least dropped in level a fair bit ,so this instantly brings in to play the depth of the heating elements /pipes , you would need to write a disclaimer to cover your responsibility for the heating before you give it a go, then why bother the risk if you have plenty of other work on me thinks :smilewinkgrin:

What about if you only take about 3mm out with a rake and sign the disclaimer aswell might be an easy job

 

[charlie1]

Just take out 3mm bri, use a fein and you could place a clamp on it that would stop the blade dropping bellow 3mm! No problem bud!

I'm always up for a challenge but not if it's going to end up costing me money. When I've done regrouts in the past, I've always gone to the bottom of the joint, this is not possible on this job so maybe it's best just to say no.

if your not happy mate walk away

I think that's best, I wouldn't be happy only cutting down 3mm anyway, all or nothing on a regrout!

I done one. Took about 2/3 depth of grout out with Fein. Wouldn't do it again, not because I was worried about damaging heat mat, but because regrouts suck. Coloured a couple since then - so if the grouts in good nick, go for that option mate.

Non flex grout used on a wooden substrate, so it's all cracked! That's why I need to get the lot out, almost impossible without damaging the mat.

Never done a grout re colour yet how do the prices compare to charging for you're labour and a bag of grout as in a re grout

 

[macten]

Easy to do - I use 2 different brands depending on colour I want. They're Epoxy based so good and long lasting. If going on flexi grout then cleaning the old grout with a diluted phosphoric acid is recommended to strip the surface polymers (obviously you wouldn't do this with acid sensitive tiles).
Paint on with a suitably sized paintbrush, leave for a few minutes and wipe off - the colouring comes off the tiles and stays on the grout.
Fast easy work, soo much easier than a regrout.

Surely it's going to crack again, and you'll carry the burden of agro then.
I would have said do it with a fein and use a clamp, but now you've said it's onto wood then it's a different job all together by the sounds of it.

I'm interested in this type of product. Do you know of a demonstration video about this?

Obviously wouldn't be suitable on this job bugs

I've got a sample bottle of universeal grout colour and seal that trade tiler sell. I'm going to try a small test area this week. I'll do a before and after pic.

Mapei do one as well

 

[prceramics]

But is it cost affective for the customer paying for the acid cleaner then the re colourer and labour as aposed to labour and grout

 

[Olz]

I priced some up recently and it was only around £20-£25 cant remember exactly, for a bottle of the cleaner and the recolour/restore which would easily do an average bathroom with 20x30's.

Much quicker that regrouting as well, so the material cost is slightly higher, labour much less.

 

[Olz]

Seems a bit of a grey area for natural stones though, universeal told me that it should be fine for trav, someone they suplied used it with no issue and to do a test area first, although the official advise was not suitable due to staining potential.

 

[NZ_Tiler]

dust free, no scratched or chipped tiles. Looks like a great product, any negatives apart from cost?

God yes!! Think of the labour (and dust) involved in mechanically removing the grout - even with a fein it's a PITA and you can never be sure you won't chip a tile. Phosphoric acid costs pence and although the colourant works out a bit more expensive than a bag of grout, it's simple and quick to do. The resulting coloured grout is waterproof and stain resistant like epoxy - so better in that respect too.

can add quieter aswell,
the fein is noisey as hell in a small room, no good if the customers home.

 

[charlie1]

I done one recently, 30m2 bathroom, changing from white to grey grout, its soul destroying but pays the bills.

 

[Olz]

This is the colour restore im going to try, well priced as well at Trade Tiler.....

Tradetiler Universeal Grout Colour

These are the range of cleaners, universeal recommended using the power clean before the grout recolour, but ive only got a sample of the recolour so im just going to give the test area a good scrub.

Does anyone know if you can go lighter with the grout colourant, say from a dark to a mid or light grey? Just for future knowledge not having used the product before.

They demostrate a grey to white on a floor on there website.

 

[macten]

Yes mate - anyway round with the recolours

Just to clarify, im not suggesting it be used for the OP's job, its only suitable for grout in good condition, we've just wandered a bit off the original topic thats all.
