Hi guys, sorry I've not posted for a while, hope you are all well? My dilema is a heated bathroom floor down using fastlex and addy, the tiles are unglazed porcelain. Should they be sealed? which grout to use Bal Wide joint with or without addy or Superflex Wide joint with or without addy. Thanks in advance for any input to this one regards Colin

Not sure what you mean about this. Are you talking about latex additive?

Yes sorry it didn't make sense.

The fastflex has it's own mix that you will have used, you didn't add anything extra did you?

If you use superflex wide joint it will be fine, you DO NOT add extra latex with this product. if you use BAL wide joint, you can mix with GT1 which is gives a more flexible grout than Superflex on it's own.

Hard to tell with the tiles whether they need sealing or not. If they are polished I would say yes, but if normal solid body then probably no. Best thing to do is test a spare tile or piece of, and see if it stains. If so then seal your floor. I would seal before grouting if that is the case.

No, Fastflex with the included mix and I will use Superflex Wide Joint as you suggest, thanks again for your help it really is a great fourm.
