20ml External porcalain tiles? HELP REQUIRED.

[Graeme]

Hi.

 

I have layed a 50m2 charcoal grey porcelain patio, but in doing so I've got quite a lot of slurry and clement residue over the tiles. I've tried jet washing them but it didn't really make much of a difference. Can anyone recommend a product or a method that will lift this? 

 

The tiles look great when wet but as soon as they dry you can see all the slurry/cement sitting on them. 

 

Thanks 

Graeme

Brick acid?

 

If necessary combined with one of those wire patio scrubbers.

 

(Done on a small inconspicuous area first.)

You could try brick acid. Start of with it well watered down, maybe 20% acid, and try it on a hidden area. If it works great but if it doesn't just increase the mix little by little until it shifts it.

+1. Got me out of the shit a good few times. You'll need some elbow grease though.

Best is to do this literally two tiles at a time or you'll be filling yourself with false hope ( as you're probably aware it's nigh-on impossible to tell good from bad when wet ).
