Grout will not harden

I was in convo with a rep and he said summit about grouts / adhesives only having a shelf life of 6 month and the chromium effects the setting or summit.....but like you say it might be rep talk...:smilewinkgrin: but the portland has a shelf life though....still worth checking before this member calls the manufactuer...then all area's are covered..

Sometimes rep tiles can tie themselves up in knots when new legislation and products are put out....

Makes me laugh for years the BAL reps swore by Gold Star for anything, then they introduced Porcelbond additive in their adhesives - THEN - all of a sudden Gold Star was frowned upon and you could ONLY use SPF...

Same with swimming pools - snowcrete or C2 no probs for donkies - now, nothing less than easypoxy in commercial installations..

I've witnessed George Hunter and Mike Lazzari in full swing hundreds of times - it's quite a sight :smilewinkgrin:

No mate, Michael Hall is PCI.

Mike Lazzari was Ardex for about 20 years, he retired about 5 years ago.:hurray:

I bought a new packet of grout.From the bar code it cannot be easily seen the manufacturing date.It is unlikely the 3 different packets are all too old? Tiles are Portuguese from Oliveira Do Bairro Homogeneo Unglazed laid on cement. All the old grout seems to be Ok apart from this spot.It could be the atmosphere too dry too damp. Should I change to a different product?

That depends what sort of m2 area you're talking about an dhow much it's cost you to date.....

..... if it's a large area and it's cost you a few quid, I would be getting onto the Forbo rep. Although he will probably squirm his way out, you want him to make it work for you.

Failing that change to Mapei Ultracolor - I'll be amazed if you can't get it in Holland.
