Questions & Answers

Can you paint the wood after using this product?

Asked by: Jordan
CommunityAnswer, where did you get the idea that you can't paint over it when it's dry? Of course it can be painted. It says so right on the label shown at the top of this page!

Wood Hardener and Wood Filler???

Do I need to use wood hardener before I apply the Minwax High Performance Wood Filler? No mention of using the wood hardener in wood filler directions. My project is a wooden mailbox repair. Thanks in advance for any advice.
Asked by: Cris
Hi Jordan, think of it this way. Wood Hardener could be used as a preventive measure even if your mailbox wood is not rotted. It strengthens the wood fibers thereby making it less prone to rot later. I'm going to use it on some shed doors I made out of Pine. Since we don't have a problem with rain in AZ, I'm going to apply it to the frame pieces before I cover the doors (skin). I want these pieces to not rot if they get rained on.

Verify this can be used on interior wood. How long before odor normally dissipates?

Asked by: niradb
It can be used indoors but the odor takes a day to dissipate. I'd highly recommend using this indoors only on days when you can open windows and ensure a high degree of ventilation. Use fans to exhaust the work area.

Do I *have to* apply anything on top of the wood hardener (such as filler, primer, paint, etc)? In other words, can I just apply wood hardener to repair spongy dry wood and then leave it like that? (I am thinking of an outdoor application where the wood would get wet again down the road.) I am aware of the white film it would form when it reacts with water afterwards, but in my application, this is a hidden area where I don't care about look at all. What I care about is cost-effectiveness and durability.
Asked by: John
Hello. No,nothing needs to be applied over our High-Performance Wood Hardener product. However, if the wood is rotting or decaying, first use an application of our High-Performance Wood Filler. Regards, Minwax Product Support

1 pt. High-Performance Wood Hardener is rated 4.8 out of 5 by 15.

Used it to salvage a rotten window sill. I also used their High Performance Plastic Wood on top. It's now a rock solid window sill that will last for years to come. Which is a big relief because it's really hard replace just a window sill without removing the window! I am now going to use it, without the plastic wood, on a less rotten sill. I'm glad to hear from other reviewers it takes latex primer and not just oil based primer.

I'm not an expert by any means, but I wouldn't recommend using this on an outdoor deck. I used the wood hardener on an old wooden deck that was splintering. The product is thin like water and smells VERY strong and bad - like using a lot of nail polish remover. It dried almost instantly on the wood and seemed to be evaporating quickly from the bucket I had poured it into, so you have to work very very quickly. The wood got very hard. It seemed to stabilize the wood. However, the container didn't mention - and I didn't realize that if the wood gets wet, it gets covered with a white film -- that doesn't rinse off. The night after I applied the wood hardener, there was a light dew on the deck. And now, my entire deck is covered with an ugly white glaze. I am going to try to sand, prep, and stain the deck - I'll test a small spot first to make sure that it doesn't end up looking any worse than it currently does. So much for trying to salvage on old deck by a do-it-yourselfer!

Rated 5 out of 5 by from works well to stabilize spongy wood before filling or painting This review is being written 1/31/2016 for the Minwax 1 pt. High-Performance Wood Hardener, advertised and sold by Home Depot. If wood is rotting, you can often dig out the worst, then apply the wood hardener to stabilize what is left. Fill the rotted area that was dug out afterwards with Minwax two-part epoxy wood filler. I've used this extensively on window sills and other exterior housing parts with great success. Prime and paint as normal afterwards (oil/latex are both fine). Warning that the wood hardener is the consistency of water, and has noxious fumes. To apply, use a disposable cup and disposable paint brush. Protect the area as it can easily splash. Dab the wood hardener repeatedly to let it soak in. It dries quickly.

Rated 5 out of 5 by from Minwax Wood Hardener Used this to stabilize wood rot on an exterior window sill and frame. Removed damaged material as best I could down to solid wood and then used an inexpensive paint brush to apply product to excavated area. The hardener soaked into the wood fibers and when dried the wood was no longer spongy. Completed the repair with Minwax High Performance Wood Filler. Shaped the and sanded before priming and painting.

Date published: 2017-08-08
Rated 5 out of 5 by from Great Product I use this primarily as a stabilizer for heavily / overly spalted hard woods and as a hardener for soft porous woods. For small spalted crafts pieces, I soak them overnight in a large mason jar, or for larger pieces, in a custom made container. Once thoroughly dried, even spongy soft pieces are similar in hardness to White Oak. PROS: > Dries Quickly > Penetrates deep into the wood > Sands well after 24hr drying > Does not seem to affect glues when thoroughly dried. CONS: > Needs to be used out-doors due to very strong odor. > Quickly gums up sandpaper if not thoroughly dried before sanding. > When liquid, can dissolve any products that use Acetone as a solvent, especially with prolonged exposure. > Doesn't come in Gallon size
