Rookie looking for support with Slate and UFH!

[ewoc]

not decided on grout yet but with regards sealants am considering the use of an impregnator that maintains the matt look to the slate.
Fired Earth recommended Lithofin Stainstop followed by Lithofin Multiseal.

I was hoping to just use the 1st or a cheaper but decent alternative and avoid use of a topical sealer??

eg:
Slate Sealer Impregnator for Slate Tiles Floor, 1 litre on eBay (end time 21-Jan-10 17:42:34 GMT)

or:
LTP Mattstone Sealer 5 Litre For Natural Stone Tiles on eBay (end time 21-Jan-10 13:58:48 GMT)

LTP Mattstone is a good product,, i use it a lot...used to use the lithofin ones but my new suppliers uses LTP so tried it and liked it very much..

I used this stuff.............very nice finish

Thanks CJ - Now that does sound like a busy few days to me...be honest!!

The LTP sealer - did it leave a shiny wet look as we are wanting to avoid this?

I was also hoping to lay my boards in same way (by which time I hope to have gained confidence) and then UFH mats and tiles directly onto this without using leveling compound....I will obviously have to be anal about getting the boards level!

Before sealing how did you clean the slate - just water and elbow grease or some chemicals?

Topical arcylic sealer though..

Thanks Dave for your info - I think I'll go for the Mattstone one

With regards tiling onto the boards do I need to prime again? or is it a case of placing ufh mat directly onto board and then tiling away?

 

[DHTiling]

If you use the cement faced boards..( which i would) then no priming required..

I know you are trying to keep costs down..but using a Flexi levelling compound will make your tiling over the ufh a lot easier...as this gives anice flat floor to tile too and no chance of nicking the cables with your trowel whilst tiling..

whats the thinnest a self leveling compound could be layed? as i am a bit tight on levels

Needs to at least cover the cables..3mm this will not alter the height as you need to sit the tile at this height anyway..
