Hi All,
I've got a tenant who has washed the concreted part of the backyard with a pressure washer, and it has partially torn it up. Spalling is apparently the appropriate word according to google, and similar pictures. There were already some cracks etc present. They are now concerned about their children falling and the rough pieces getting stuck in wounds etc.
I've got no problem repairing it as pressure washing is a standard process and the concrete should stand up to that. Its simply old concrete. They are good tenants and recently agreed to a $20 p/w increase.
I really don't want to have to rip it all up and relay and have seen that a potential repair could include resurfacing with polymer laced concrete product. Has anyone used one? Anyone have a particular product they would recommend, or an idea of the costs?
Obviously not expecting a repair to last forever, but a few years would be good.
Some parts look like they will need to be relaid (the middle part of the photo), but could the others be spot filled to level it, and then the polymer surface coat applied to the entirety for uniform appearance?
Any other suggestions appreciated? .
Cheers,
Paul
