You could sell virtually anything on eBay and someone would buy it, apart from Geofix :pPablo wrote:ebay or gumtree should shift it quick enough.
We've got easipoint coming down tommorow to train up all our staff in installation. Fairplay, they've sent 2 guys down and put them up in a hotel for the night. Pretty sure I'm not going to learn much new myself but should be good for the girls in the office to see it done. It was free of charge as well, so why the hell not?

We had the easipoint training today and we learnt a lot to be fair.
1. Wetting the edges of the slabs beforehand reduces the chances of picture framing.
2. With no exceptions it must be mixed mechanically.
3. Once it is mixed in the bucket allow it to off for five minutes and then mix it again (this gives the mix a much longer shelf life in the gun)
4. Allow it to go off for half an hour in dry warm conditions and up to an hour in cold conditions before tooling it off. We always thought 10-15 mins was adequate but you need to wait until the mix goes crumbly. This plays a big part in reducing any staining on the slabs.
They've also got a cement based product for slurry pointing as well. They've got this big motorised sponge which you go over the paving with after to remove any cement stains. All in all a good show and take my hat off to them for putting the effort in

Unfortunately I've discovered the same issues with Rompox Easy, after 6 months the product shrinks and loosens.
This is a real shame as it looks great when first applied and with joints setting hard, after researching thoroughly I'd hoped this product would do what it says on the tin but unfortunately it needs further development.
The two jobs I've checked are decorative stone flagged areas, there's no foot traffic so the jointing material is still in place and reasonably hard, I'd never considered using it on an area with plenty of foot traffic but now won't use it full stop. It's back to traditional sand and cement joints as I can't justify using some of the more expensive two part products on domestic jobs.

I'm thinking of removing my Rompox Easy and replacing it with gunned in sand & cement.
I know many of you use Easipoint but the cost to us non trade people plus the carriage makes it expensive, especially if you over order cos the job is a one off. Under ordering means reorder with more carriage charges.
I was reading elsewhere that people have had success with buying ready mixed mortar like this
http://www.diy.com/nav....9273109
and use it with plenty of plasticiser.
Supposedly the sand used in the mix is a very fine grade and coupled with the plasticiser makes it good for gunning.
What are your thoughts?
