Thread: DIY decorative concrete

SWMBO and I have just finished applying 20 SQ metres of decorative concrete. We did so to hide a botched concrete job done by a neighbour (good bloke, bad concretor) . It came out beautifully.

The point is, if you have some suspect or tired concrete around your home that you need to repair, try spraying on resurfacing compound. It's not that expensive and you don't have to use the stencils (we didn't). It cost us $60.00 for a hopper gun from Trade Tools, (you obviously need a fairly good compressor), and $380 for the materials.

This is made up of of a 20 litre drum of Polymer (which is used in much the same way you use bondcrete, apply a mixture to the bare concrete, and then use it to mix with the sand/cement spray on stuff), three 20 KG bags of the coloured sand/cement mix, and 20 litres of high quality sealer.

The process itself is pretty painless:

acid wash the concrete (20:1)
Mask for overspray
roll or mop on the polymer solution
Mix and spray on the coloured cement solution (we did three coats)
When it's dry roll on the sealer (two coats)

We only used half of the polymer solution and a two thirds of the sealer. We plan to go around our whole house with it.
