There's a wealth of info on the main site inc a path done in it in Wales

Our villa in Majorca had exposed pebble floor was great although I bet cleaning it was a pita

Rugasol is what you need. It's sugar and water with a bit of food colouring to make it look all science-y.

Mix the concrete with your preferred deco agg, or make it a face mix, spray rugasol @ around 250ml per mÂ², leave it 4-6 hrs (bit longer at this time of year, and then hose off.

That makes it sound a lot simpler than it acctually is, but the principle is there. A 1mÂ² test panel is *always* a good idea!

Sika no longer stock Rugasol.

We use Pieri VBA Bio 2 its 10 quid a liter but you would be better off with 1kg sugar/5l water for your 5m2.

If you do use the sugar water don't apply to soon. Were as the bio 2 can be used as soon as the concretes flat

Using a gap graded aggregate has the best effect IMO.

sorry jay,what is a gap graded aggregate?

Graded aggregate would be say 0mm-10mm (there is to many fines for EA)

Gap graded would be 6mm-10mm

Your best bet would be to buy your aggregate from a garden center, their decorative 25kg bags are nearly always gap graded.

Same goes for the sand you need to use 0/2 (not sharp)

Hi Tony when I do exposed aggregate I buy washed stone in bulk bags and take it to a local batching plan. They add it to a clean hopper and do the mix for me and deliver when arranged. I don't like the scattering method because the base aggregate always shows up and lessens the decorative stuffs effect. I use a liquid surface retardant from Larsen which means I can do all the pouring one day spray it on then clean it the next morning regardless of the temp. Buying 25kg bags is going to be very expensive if you need a few tons of the stuff. Quite often I add a basalt grit to the mix which gives the grey base colour and nice black fleck.

looking forward to thte result, re the deco gravel i had a big job on needed 12 tons deco bulk bags were like 80-100 a bag, managed to source the place in the local quarry theat bagged all the stuff for most the builders merchant in the northwest, town and country aggregates based out of the big cemex quarry at dove holes, i could buy it for 12 a ton collected, i know luton might be hard work for quarries etc but 20 minutes serching rd asking lorry drivers etc can save you a lot

take some pics as youre doing it

This has got me all intrigued. How long does the m agic sugar water retarder take go work its magic? i.e is the scrubbing and cleaning the next day or 5/6 hours after application?

Would be keen to see the test panel luton!
