What type of concrete resurfacer to use?
i bought a house that had a plain 4" concrete patio put in a few years before i bought it. it started spalling this past winter (in the northeast) and i've received 2 types of resurfacing bids that are similar in cost. wondering which method would be superior, or does it matter? thanks.
method #1 - prep patio using acid wash then use CR-90 concrete resurfacer

method #2 - prep patio using diamond grinding and/or sand blasting then resurface using Stampcrete Re-Do-It polymer resurfacing kit. Finish with Clear seal #9000.

No one will guarantee longevity unless they rebuild it from scratch (which seems a bit excessive). The best i've been able to get is Bid #1 said they've done this work before and they haven't had to redo it.
Doing more research on the 2 types of concrete used, they both seem to be about the same. The difference appears to be the method of preparing the existing surface and the clear acrylic sealer to finish the job.

i've been told by several contractors putting bricks on top wouldn't be a good idea due to it being uneven over time. no one can guarantee the soundness of the existing substrate. i thought about this and if no one will guarantee it than how will the resurfacing be any different?
its been a frustrating process. i got many proposed solutions including extending it, raising it, demolishing it and resurfacing it with all sorts of materials (kool deck, other polymer based solutions). i've narrowed my choices down to the 2 above.

Concrete re-surfacing, even with polymers; bonding agents; etc, is going to crack again. Concrete is rigid and it will always crack. Brick and mortar should give you better durabilty, as long as it is properly sealed.( with a high grade sealer like Double 7) Tumbled pavers, 6"x9", are like $1.20(LOWE'S). That's about $4.00 per sq.ft. Pick up some commercial grade motar mix(LOWE'S) 80 lb bag $5.00. Start at the highest point and level across from there. 1/2" bed-joint, and if you have to build it up more than that in an area, use bag concrete. It's a weekend project, that costs you about $5-$6 per sq ft. Seal it, per sealer manufacturer recommendations. Thompson's(JUNK) Every year, and it's about $40 per 5 gallons; or Double seven every seven years at $150.00 for 5 gallons.

thanks for the do it yourself method. what i'm confused about is i have a concrete walkway leading to the patio and in the front of my house that's been in place for 50 years and not a scratch on it. why can't this resurfacing perform the same?

I'm not a fan of sealers but I agree with everything else Brick Guy said. It will last the longest at the best price.
There is no way that any of that resurfacing stuff will match your existing driveway time wise.
