Topic tags/keywords: question concrete patio

I have a 9 year old concrete patio with a brick edge border that needs some masonry repair. I need to replace some “divots” in the surface and several of the mortar joints need to be replaced.

I picked up a broken bag of Masonry cement for a $1 at the big box as well as a broken bag of sand for a $1. The cement bag states that type “S” mortar can be mixed by 1 part cement and 2 parts sand, so I think I’m good with that, but I’m wondering if I can just mix the cement with water and use it to fill in my “divots” from the aggregate pops int the patio field. I did get a bottle of the bonding adhesive too.

It goes without saying that the persons at the big box didn’t know anymore than I did from reading labels, so here I am where I know I can get some educated feedback. Can I get this whole repair done for less than $10 or should I get a different product for the patio surface?? Please help me out before I have to tell the wife that my idjit repairs add “Character” to the patio.

The answer to that question is NO. To fill in spalling, you must make sure the surface is clean and free from loose debris. I would suggest a good power washing after sweeping, vacuuming, prying and/or chiseling out any bad areas. Then you need a bonding agent and apply it to the areas before you apply a patching compound “designed” to fill in the spalling areas. Mortar mix is not made to hold in spalled areas. Hope this helps.

It would be the masonry cement wouldn’t it?? It’s mortar mix when mixed with the sand @ 2:1 The only patching compounds I could find at the store were latex types that’ll look like hell, which was why I thought that cement on cement would be the same thing. I’ve done all of the requisite cleaning an loose debris removal, just looking to get a low visibillity repair, sorry if I was unclear

ChefHDan, Most of the good products like Miracote and Ardex require a certified installer to use their products. I do not know of any do it yourself product that will give you the same quality. See if there is a qualified installer in your area by contacting the Concrete Network in your area. When it come to patio,s and the like, for repair I personally like Jewel Stone, but its a little expensive. The repairs can be stunning, plus the stuff is tuff and lasts. When applied correctly it will not separate like a lot of products due to moisture transfer that can cause delamenation.

if you increase the sand ratio to 2.5:1 or 3:1 you will get a thin application sand mix closer to the patching premix sold for about $4 per bag. i would splurge on the $4 purchase and mix with bonding agent as well as wet the area with bonding agent immediately prior to application. the best repairs come from cutting out the spallled area and doing a fuller thickness pour/repair. good luck with making your wife happy….
