I have a large area of paint veining on a painted WOOD BEAM. All 3 sides would have to be skimmed, sanded then primed and painted. It this the right and best product for the job? As we all know, WOOD expands and contracts with changes in humidity and temperature so will this product stay put over time. I will also be using this on the painted wood window sills and casings where large areas of multi layers of paint have become loose, and will be removed. I need to use this to fill those voids or at least feathered out the edges between old, but solid paint, and exposed wood where the layers of old paint has blistered and cracked. Also the painted beam is approximately 15 ft x 6 inch x 3 sides. How many cans would I likely need? Thank you in advanced.
Asked by: Peter
Peter, our Ready Patch Spackling and Patching Compound should work very well for the wood beam, as well as the previously painted wood window sills. You can expect one gallon of our Ready Patch to cover 13 square feet at a thickness of 1/8". the beam is 22.5 square feet total, we hope this helps you figure out how much product you will need for the job.

I purchased this under recommendation from internet sources after finding that DAP drydex would not cure hard even after 24 hours despite it turning white one hour after application with a thin coat. pros: 1. cures harder 2. cures relatively fast 3. more durable cons: 1. due to fast drying can be a pain to use over large surface areas as fast drying process causes streaking. 2. due to con number one this means you will have to sand. 3. make sure you are in a ventilated area as it does give off fumes. bottom line: it gets the job done unlike other products that still are soft and fragile after cure. Honestly, I will never use the other product again.

I used it to fill in nail holes in the coffered ceiling I installed in my garage. Doesn't everyone have a coffered ceiling in their garage? Got to fill in your time somehow. Anyway, MH Ready Patch spreads on nice and dries hard. Sands easily. Did a great job of concealing the nail holes. So glad I used this instead of spackle or wood putty. Primed and painted after applying the MH. Highly recommended.

Rated 3 out of 5 by from good spackle, could use plastic container This is the best of the readily available spackles, but like all spackles, it shrinks to a degree. Its odor is also slightly irritating as it contains mineral spirits and VM&P naphtha. My issue with it is the packaging. It comes in a metal can. The spackle solvent carrier is an emulsion of water and mineral spirits. I use half a can at a time, then put it on a shelf for a few months as I am a handyman and save it for future use. The problem is that the can rusts internally from the water vapor. Specks of oxide drop onto the surface and down the sides of the shrunken mass. The remainder of the can is unusable and must be tossed. This has happened to three cans of this I bought over the years. A plastic tub would be much better to my thinking as the rust problem wouldn't exist.

Rated 5 out of 5 by from MH Ready Patch works I used this product on the exterior of house built in 1978. The old T1-11 siding was checked and cracked and in places had a honeycomb look with pin holes. I took the surface down to bare wood and primed with Peel Bond. The I used ready patch, sanded and primed again. When my finish coat was applied the surface looked awesome. I like this product because it dries quickly, sands smooth and is very easy to use. I had no issues with bubbling or peeling over the patched areas. I highly recommend this product.

Rated 5 out of 5 by from Very Happy I have been very happy with this product. I have used it on exterrior jobs to prep facia boards for paint and also on craftier jobs. On one project in particular, I used it to fill all the cracks and voids in a project I built from low grade plywood. It took a few applications, but by the end everything was perfectly smooth and ready for paint. After a paintjob you couldn't see any plywood cracks, joint seams, or plywood edges.

Rated 5 out of 5 by from H W Ready Patch great stuff This "spackle" was a revelation--unlike other spackle, it can be used anywhere, and it's completely easy to handle and work with. I have used it on wood, plaster, and outdoor brick. I even plugged large voids with it, drilled into it to hang stuff, easily rebuilt cracked and sagging plaster knee wall, rebuilt deteriorating porch trim. It takes paint beautifully --in short, iit is holding our old house together--literally. AND, if that was not enough, you can paint over it as soon as the surface is dry--minutes. It goes on smooth as satin, but you can also sand it. It spreads so thin with a wallboard knife that even an amateur like me can feather it out to turn uneven cracked areas into smooth wall. Love this stuff!

Rated 5 out of 5 by from Great product I've used this product to repair missing wood from fascia chewed by a squirrel, deteriorated garage door side trim near the ground, and water damaged soffit. It dries to a hard surface that's almost like sanding wood and can easily be blended with the surrounding area. If appled in thicker coats it takes a lot longer to dry than light weight spackling to dry. I've experienced no shrinkage and the repairs I've made with it look great.

Rated 5 out of 5 by from My Go-To Product for interior wall repair. I've used Ready Patch many times for interior plaster and drywall repair. It applies well, sands easily and is essentially permanent. When used to fill larger holes it is necessary to apply in multiple applications to allow for minor shrinkage and drying - which will take at least 24 hours. The resulting patch, painted over, will be invisible.
