The one I did here at the house was on a 3 year old floor. However, the hangar floor was recently poured when the club built the hangar and I'm certain there wasn't a 6 month wait before we put that coating down. I'll get the name of the system here and post it as well as check on that waiting period. I was hoping to do mine within days of garage completion. |
Just found this info on the web, it suggests a minimum of 30 days.if under 4 inches thick, mine will be closer to 6 inches...
If applying epoxy coating over a new pour, it is suggested that you wait a minimum of 30 days before coating. For concrete over 4" or 5" thick it is suggested that you allow even longer for concrete to cure. To test if concrete is fully cured, (or if there is still moisture present), tape a 4' x 4' sheet of clear plastic in middle of floor and leave in place for 24 hours. If not fully cured, moisture will be trapped beneath plastic sheeting and surface of concrete will appear dark or wet in that area. Remove plastic and allow to fully cure. Repeat test once every 3-5 days until there is no noticeable difference in concrete appearance beneath and around plastic sheet.
The surface of freshly cured concrete may sometimes have a milky-white residue. This is called concrete efflorescence, and must be removed prior to epoxy coating application. Efflorescence is the deposit of salts, (calcium, sodium, potassium, magnesium, chlorides and sulfates), which rise to the surface of concrete. Heavy accumulation of the efflorescence can be removed with a stiff brush, residual salts can be removed by washing with clear water.
