Maybe go to lunch and leave a big fan running while I'm gone. Even if I don't think 3 coats can fully dry in 24 hours, I can skip a day and still only make 2 trips with 48 hours in between.Īnd for the same reason I'd want to do a skim coat and paint in one day. If I'm making it in someone else's home, I'm definitely using setting compound and putting on 3 coats in one day. If I'm making that repair in my own home, I'm definitely using premixed compound. And since I have a minimum charge of $90 for a trip, the customer also doesn't want to pay $360 for 2 hours of work.Ī DIYer doesn't have to deal with that. That's over 3 hours of driving time to do what is probably about 2 hours worth of work (not counting paint matching). Let's say I have to repair drywall on a wall and paint. I think the speed factor is more important for the contractor than the homeowner. Always remember, the cost of plastering a home varies from wall conditions to the finishing you need. One day is better than two days, and one week is better than two weeks. Well, some people just don't want their homes in disarray for very long. If setting-type joint compound dries before it sets, bond failure may result. Do not use setting-type joint compounds for thin skim coats.Ħ. Then again, did he actually read the manufacturer's instructions? Maybe find out what he's using exactly.ĥ. It might not matter very much if the setting compound is a little weaker. Then if you put fans on that it will dry and harden normally.ĭoes he get good results? Maybe. What they should be doing if they want to get it done in one day is use a standard drying compound. What is the sense in using a fast setting compound and then drying it out too quickly? It's pointless. If you don't keep it damp, then you're just making it weaker. It has to stay damp as it sets for it to set at full strength. He is right that fans will help things dry faster, but here's the thing about that - assuming he means a setting compound such as USG joint compound, you don't want a setting compound to dry faster. Either material you use, it still has to dry before you can sand and paint it, and fast setting compound does not dry any faster than drying compound. I don't know why anyone would take days to complete that (unless he means "two days"), but his technique makes no sense.įirst of all, the issue has nothing to do with fast setting compound vs.
