Skimmmed it over with Durabond, then Easy Sand, another coat of Gardz, 2 coats of paint feathered into the other half of the rolling ceiling that looks to be the next area to start coming down. I made sure to push enough Durabond so that it would squeeze up and through the wood lathe to produce new keys. When your buddy was in the attic, did he notice any damage or crumbling of the concrete keys going up through the wood lathe? If so, you will need more help than I am qualified to give, although I recently did a 3' x 5' section in a plaster ceiling where I cleared out as much loose plaster, re-nailed all the lathe to the studs, secured the outer areas of plaster with plaster washers, screwed in a section of drywall, then filled all the gaps between the drywall and the plaster with Durabond. If it is all little spots less than 10" in diameter, I would skip the pink. You really don't want to have to sand Durabond! Just make sure not to overfill so you can minimize your sanding. If you want to keep the refreshments coming, I would first use Gardz, then do the pink, then first coat with Durabond, then Easy Sand the rest of the way. I am no expert on plastering, but in my mind, the Gardz will provide more strength to the material you are going to skim over than the pink glue will as the pink glue is thicker and will tend to stay on the surface. If you drop a glob of Durabond and let it dry it will stick like glue to the floor and you might damage your spackling knife trying to scrape it. I suppose you could apply some pink glue over the area you have Gardzed, but if you skim first with Durabond, I believe that the Durabond will provide a "durable bond", hence the name Durabond! If you drop a glob of Easy Sand on a floor and let it dry, you can generally take a taping knife and scrape it right off the floor. The thin Gardz might act like a wood hardener that is thin and soaks into soft, decayed wood and hardens so that it is now stronger and more workable. I would want this as the material that did not come off is probably in the process of degrading as well. If it were me, I would smoosh on a heavy coat of Gardz as it is thin and will soak into the material you are seeking to skim over, hardening it in the process. After you apply the pink stuff and let it dry, the water in the Durabond or Easy Sand will reactivate the pink glue to help whatever you are skim coating with th adhere to the ceiling or wall. This pink glue will stick to the surface you want to skim. The pink liquid you refer to is either Larsen's Plaster Weld or USG Plaster Bonder. Is there a bonding agent that will work for all applications, or do I need to know the type of plaster used (I'm not aware if there are many different kinds). I have watched the mudders put a pink liquid on the area after cutting the loose stuff off. I was going to do one coat of durabond and top with 2-3 more of easy sand after that, PVA prime and paint. My question is do I need to put a bonding adhesive on the concrete looking area first. I have seen repairs in the past, and know how to float compound well enough for this application. My friend is cool with a tailight warranty since he will be paying me in frosty beverages, and saving $$$. I have an old timer that I refer my plaster work to, because he has 40 years experience, but I want to try and experiment on his place. The areas are where plaster has delaminated from the concrete substrate that is attached to the lathe. There doesn't appear to be an issue with water, no staining or visible leaks when he was in the attic the last week or so. Got a friend that has some peeling in a few areas of his house, 1 room has some ceiling areas and another has ceiling with a spot in the walls, all about 10" in diameter.
