How to colour concrete, to match slabs.

[ericmark]

There was a sloping drive to a garage, garage made into a flat, and outside the patio door I have built up the ground so I can have a level area for seats etc. This has left me with a little of the slope left and I want to fill over that tarmac to level it out, just to remove the trip hazard with the edge of the slabs, but the slabs are a yellowish tinge, I would like concrete to match.

Buff coloured cement dye or masonary paint

Definitely not masonry paint!

Buff dye is the answer.

Or just buy buff slabs, probably a much better match and will look better in every way. Chop up as required.

Slope is the problem, either need to band jack the tarmac out, or fill with something, and my SDS does not have a rotor stop, and don't have a grinder. So you think this will do the trick ?

Yes mix it up with water and tryit, but might need a few coats to get the colour depth.

Why not masonary paint. Once appliedd to render and dried it can be pressure washed ok. It doesn't seem as though it is going to get much traffic there.

Coats? It's dye, to mix with the concrete!

You need it coloured right through. Using any paint on non-dampproofed concrete will result in a blistered mess.

I'd use 10mm pea gravel and more sand than normal, to maximise the dyed slurry that sits on top. 1 cement, 2 sand, 2-3 gravel.

Sorry I have misunderstood the post and the pic. Just re-rread it and looked at the pic and now realise it is a tarmac strip. I thought it was unfinished concrete.

Replace it with more yellow slabs.

Great picture, by the way.

Oh, fill over the tarmac? In that case you can't!

Do it properly - dig it out and replace with something else or just accept it as-is.
