Customer Questions & Answers

Can you paint the wood after using this product?

Asked by: Jordan
Can you paint the wood after using this product? Asked by Jordan April 22, 2016 I wondered about this product too, and emailed Minwax Product Support yesterday. Received a reply dated 6/14/2017, 0943 AM : "Thank you for contacting Minwax. We appreciate your inquiry. Yes, I'd suggest using an oil-based Primer first, then latex or oil-based Paint. I hope this information is useful. Please let me know if you have any other questions. Best Wishes, Roger ....... Minwax Product Support"

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
No, if the wood you are using the filler is solid and free of rot then you do not have to use the hardener.

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 need the tube of wood hardener to mix with the wood filler?? Very confusing, since all the videos I've found are showing a tube of Minwax wood hardener that is mixed with the wood filler. What is the difference?
Asked by: Barbara
Hello. We apologize for the confusion, the tube does come in the cap of the product. Regards, Minwax Customer Support

1 pt. High-Performance Wood Hardener is rated 4.9 out of 5 by 11.
Rated 5 out of 5 by from Worked as advertised. I was surprised and relieved to find out. Used it to salvage a rotten win... Worked as advertised. I was surprised and relieved to find out. 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.

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.

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

Rated 4 out of 5 by from Great stuff, but be sure to paint! Just completed repairs on rotted wood around an outside door, so no long-term reports yet, but that part went well. Very easy to use, dries quickly. While I was at it, I treated the bottom edge of the fascia above the door, as well as some areas of deck railing that were weathered. The product dried to a hard, shiny finish, so I did not bother to repaint or restain those areas. After a rain, I noticed small white spots all over the brown decking where I had treated the wood. There were also large white drip spots on the deck below the fascia I had treated. I was unable to scrub the spots off; I may try acetone to remove them. I believe water on the unpainted product caused the white residue. So beware if using this product on a nonwhite surface, and be sure to paint over it after using.

Rated 5 out of 5 by from For Craft People Besides wood...if you do any cardboard projects, paint this stuff on...cardboard will get hard as plastic and can be sanded smooth. Do this outdoors as this stuff is a bit smelly.

Rated 5 out of 5 by from Minwax Wood Hardener There were a couple pieces of railing out on my front porch that were starting to soften and eventually rot right through. I really hated to replace the boards just for a couple small patches. I looked this product up and decided to try it. I applied the hardener and within a couple hours it had dried. I recommend two coats, but even with one coat the product worked very well! The once soft patches are now very hard and durable.

Rated 5 out of 5 by from Very good stuff Repaired a n exterior door with wet rot spreading due to improper pet door install by former owner. I started with a spongy portion of door I could easily push a screwdriver all the way through. I got out the worst of wet rot, then used hair dryer for a couple of hours to dry out the rest as best I could. I then used old throwaway paint brush to apply product to exposed wood. I think the most important thing i did was drill several holes on each side of door around perimeter of the rot and use small pet medicine syringe to inject product into drill holes. I did about 5 coats. Rotten area went from consistency of wet Sunday newspaper before to knock on wood solid after. Plan to finish repair with a 2 part epoxy type wood filler now that I have something solid to build on. Great product. It does leave white residue if exposed to water before painting as other reviewer said.
