Customer Reviews for Custom Building Products Fix-It-All 4.5 lb. Patching Compound

I have been using many Custom products and have always been satisfied.Their grouts are top of the line. I really like this patching compound. I usually use to patch wood doors exterior steps etc. I think if you want slower cure time. Your supposed to add some vinegar. I sometimes add wood glue to make extra strong batch. (No vinegar) YouTube taught me that one.

This stuff is amazing, dry's like concrete, hard to sand, however for filling wholes in wood, drywall, concrete, it works great, does not crumble and you can put it on thick whiteout cracking

I've used Fix-it-All for 20 years. Getting the mix right is an art, aim for mash potato consistency. It definitely takes a few tries. I do maybe 1/3 warm water to 2/3 powder. Mix fast as possible because it can harden rapidly, especially when it's runny and wet. Shape it almost perfect asap. I use it to fill minor screw/nail holes, knot holes on plywood. It doesn't do so well on corners that gets a lot of impact. * Recently 2 batches turned out really chalky & weak even after 12hrs.

I have been using fix it all for over 40 years in construction and 10 years since retiring. It dries fast and can be painted over outdoors. Great for plaster and wood repair. I always keep a box on hand!!!

Easy to use but need to apply quickly cause dries out quick.

Best product fills gaps no sag hardens quickly. Thanks

Worked well on interior plaster wall.

Been using for years. It's a powder, so I don't need to worry about it drying out between usages. Just add water to as much Fix-It-All as you need. Add more water to thin; more powder to thicken. Then patch away. Once set, you can sand and paint it (although you should get it close to what you want, especially for larger areas, since it dries hard and can take a while to sand).

Good product to use.

This material has a really strong adhesive and it’s good for patching up any type of surfaces and material. Used it on patching up a door and used it for patching up a stucco wall

After my tooth filling fell out, I bought some Fix-It-All, mixed it with a little water and replaced the filling. In reality, I used it to patch some voids in drywall, prior to mudding and taping. Worked great!

Works on everything.

Been using this for years! Strong bond, excellent for patches. Can’t beat the price!

I remember this from the 70s, and it suits the need better than many other similar products on the Sam shelf.

good stuff, Have used it many times over the years, it fills and sets harder than drywall mud

The product mixes very well and is easy to apply. It also dries fast which helped a lot..

This stuff absolutely is garbage clumps up and dries in the pan way too fast and is horrible to work with
