Pebble Overlay (over existing concrete patio)


Can you tell me what is the best way to remove the pebble overlay? I am sure when kept properly this is great, but when the yearly maintenance, as you posted, is not done this is a horrible product to use outside. We have this around our pool and have not done the maintenance (did not know it was needed) and it is coming up. It is terrible to walk on in bare feet and gets into the pool. We would like to remove this to expose the concrete below. How can we do this? My adivse to anyone thinking about applying this is don't do it in an exposed area. It looks wonderful in the beginning but when it begins coming up, it is horrible. Any advise would be greatly appreciated.

Pebble Overlay (over existing concrete patio)


Bud was absolutely right about the pebble coatings not being satifactory in cold, variable climates. Here, concrete with the right aggregate and a retarder spray is the most common.

I had a small exposed aggregate (12x22) section put in by a contractor friend and they ordered the "McDonalds" mix (3/8" to 1/2" rounded river rock) that is always available. He just ordered 4000 psi air entrained for the 4" slab and it came just as soon as ordinary concrete. The finishing is easier, especially if you have experience and it just a matter of washing early the next day, brushing and a wash that takes about 20 minutes. It is usually sealed then, but not necessary later. It looks like the exposed aggregate at many restaurants and the exposed aggregate concrete trash containers and benches at some McDonalds, so it is not that unique.

For a 4" slab, cost extra is minimal. I have had my slab for 5 years with snow and temperatures between -25F and 105F with no maintenance necessary. It has worked well for me.

Question

Pebble Overlay (over existing concrete patio)


How is this product different than the one used in thread # 15 by Bud? I live in PA and am so confused as to whether this product works or not maybe something new has been developed it has been six years since it was posted.Thanks
