Terrace Tile Grout

Hi,

I am using Google Chrome to translate both the AKI and Leroy Merlin websites to look for 'Brick Acid' to clean excess mortar from when the the tiles have been grouted by a previous owner, as well as a grout suitable for re-grouting exterior ceramic floor tiles and am getting totally confused with some of the translations for the grout, as for the brick acid I can't find anything.  

I believe the new resin based grouts last quite a few years before having to be re-grouted again and I would also like the option of either Grey or Black grout

Can any fellow EOS DIYers offer any advice on the Spanish names of suitable products, or recommend any products?

Thanks

just found that Brick Acid is 'Quita cementos'

grout is called pasta de juntas ( joint paste ) and normally comes in white, grey, beige or black, 

Kelju,    Muriatic Acid is used to clean mortar off bricks, tiles etc-

However agua fuerta (about 20% hydrochloric acid) does the job very well.  But be aware, just like  muriatic acid,  it is very corrosive, so whenever you are using it exercise extreme care.

 I am still astounded that it is usually to be found on the bottom shelf, at children in pushchairs level, in the supermarket.

Cemento Blanco (which also comes in grey) is a waterproof material which is used in swimming pools and works well as a grout.

Thanks both,  any idea what Cemento Cola is???

Is it tile adhesive?

It is tile cement for fixing tiles. Cola is a general word for glue, although it has other meanings too

Dont use brick acid on tiles you NUMPTY HEAD you will destroy the glaze and the tile will be ruined some people

Thanks johnzx

hughjardon - I will bear your advice in mind.  The apartment belongs to my Son who is not practical in the DIY sense, he has only just bought it and I visited the apartment for a couple of days shortly after the purchase (hence all the questions).  I noticed the terrace had had a previous attempt to point the tiles usng a sand and cement mix and that most of this had in places been smeared onto and over the edge of the tile making it look a right mess.

I am only trying to establish what I might need when I revisit in June, when I thought I might help him out and re-grout his terrace for him, if the mortar mix will come of the tiles easily then there will no need to use anything any harsher than soap, water and a scraper - just hedging my bets that's all.

kelju, It is most unlikely that you have glazed tiles:   Firstly because that kind of tile is very slippery when wet, thus not suitable for a terrace floor,  and secondly, it is very unlikely that mortar mix would stick to a glazed surface (even if one wanted to do tha).

Also, aqua fuerte is used widely in Spain to clean the calcium depot off toilet bowl,  i.e. a glazed surface just like glazed tiles. 

Of course if used on tiles, once the mortar has been removed one should wash the tiles with clean water. (taking care not to let the 'contaminated' water run down onto any property below yours).

Thanks johnzx, practical advice as ever.
