What Customers Are Saying
Customers overwhelmingly praise this repair kit for its effectiveness and seamless finish. Most highlight the fiber-reinforced formula creates invisible repairs after painting, with the thick, spreadable consistency requiring no special tools. Many emphasize quick drying time—ready for sanding in under two hours—and versatility across drywall, wood, vinyl, and Styrofoam. The reinforced patch eliminates complex backing installation. A small group reports adhesive backing occasionally fails on uneven surfaces, though most still recommend the product overall for professional-looking, durable repairs.

Rocking Chairs
Would RecommendIt works with plywood restoration if you are using the restored piece as display, but wanted to keep as much of the original as possible.

Works great
Would RecommendThis stuff works great and is easy to work with. Had 2 different homes with large holes, covered great and has lasted a couple years in one home with no issues. FYI, large holes i like to fill and use a self adhesive patch and finish. Worked great.

Widely useful for house painting prep
I used six containers of this 3M product on my redwood siding during house painting prep. I closed up 5 inch vent holes, reconstructed broken trim, planarized soffits with chipped paint, covered nail heads, and filled cracks and knotholes. I generally let the putty cure at least 48 hours before sanding and priming. The resulting repaired surfaces are flawlessly smooth and hard.

This stuff makes the job so much easier. Had a few large areas to repair and it filled the area with no problem and goes on smooth and easy. I waited a week before I sanded it to make sure there was no shrinkage and to my surprise there was none at all and it sands easily. Made the job I was dreading to do easy and took paint well.

Best Product EVER!!!!!
Would RecommendWhere has this product been my whole life. My husband and I bought a 90-year-old house with wood clapboard siding. My husband said he could be a spokesperson for this product! When we painted the outside of the house, we had the scrape the old paint off. We found some larger holes in the siding and a couple of places where the there was a little bit of previous termite damage on the end of a couple of boards. We also found places like you see in the first photo where the end of the board has rot...

Not for textured stucco
Would Not RecommendI was looking for textured stucco repair for cracks on the outside of my house and this was the product that showed up, so I bought a small container (thankfully!). When I wanted to go and use it, I was told, that I needed a sand and concrete type mixture, not this. This is for smooth walls for indoor use. However, since I had bought it and opened it, I didn't try to return it either. Lesson learned.
