In my previous post I noted that road brin is the culprit of deteriorating concrete this winter. We have never seen so much damage even from rock salt as we are seeing this year. I have done the research and can assure you that brin to melt snow is definitely the issue.
I 29 years of stamping concrete I have never had calls regarding deteriorating concrete. Brin goes through sealers and dramatically destroys concrete almost immediately. The winter solution is to park all vehicles off the driveway during the winter. Even my SUV that we rarely use was used in one snow storm and where it was parked has spots that have been compromised. More patching. Thank God we used color hardener by L.M Scofield to do the job. If this were integral color not repair would be possible since color could not be matched.
There is a solution to be able to park your car on the driveway in winter without worry of damage. The product that we now can use is salt guard. Stripping sealer and applying salt guard prior to resealing with give the protection needed to prevent brin damage. This is a relatively new product but has been showing great results. Remember that we recommend striping sealers by wet sandblasting like that done by Atlantic Green Pro here in New Jersey. All other chemical stripping in my opinion is not effective. If any sealer is left behind poor salt guard protection may occur or new sealer may become white as a result of old and new sealer not being compatible.
