What Customers Are Saying

Customers overwhelmingly praise this exterior patching compound for exceptional durability, ease of application, and versatility across diverse surfaces including fiber cement, vinyl, wood, stucco, and metal. Reviewers consistently describe it as creamy, ready-to-use, and simple to spread and smooth with minimal sanding. Many note repairs have held up for years through storms and weathering where previous products failed. The quick drying time allows painting the same day, and users report achieving smooth finishes by dampening surfaces after application. A few mention storage consistency issues, but most consider it a reliable, high-performance solution.

Partially dried out

Would Not Recommend

When I opened the container it was partially dried on one side of the container, and dried on the lid. I needed to use it today and didn't have time to go back to Lowe's 22 mi. away. Product did not apply well. I will update if I am able to exchange for good product.

Great Product!

Would Recommend

This product turned out better then I thought. It is easy to work with, longer working time than mixing plaster with retarder. Can be used outdoors which was my intentions and is water proof. I would definitely recommend this product.

Simply Awesome

Would Recommend

DAP Patching Compound is the real deal. It kind of looks like spackle but it is far more versatile and durable than spackle. I am repainting kitchen cabinets that were installed 20 years ago. On installation there were gaps, uneven angles etc between the cabinet frames. DAP Patching Compound is doing an outstanding job of leveling everything out. It sands perfectly level, has great adhesion and is tough as nails. I can't speak for exterior durability but will be trying it out on some exterior pr...

Perfect product for patching Hardi-plank siding.

Would Recommend

Exactly what I've been looking for. I had two Hardi plank siding repairs that needed done. One board had a long chipped up bottom edge. The other had a fairly deep hole where a limb had hit during a storm. DAP patching compound was easy to apply then sand to a perfect finish. I have primer on them and ready for paint.

Worked great for repairing retaining wall.

Would Recommend

Repairing cracks on the top surface of a treated 6"x6" of a retaining wall. After ~35 years, starting to look a little ragged. The filler worked great, great adhesion, easy to apply. Dries REALLY hard, but have had success sanding it with 60 grit with cordless sander. Too bad it's so bright white, but will paint (high quality latex) to match the rest of the stained wall. Would buy and use again, for sure! It would be neat if they could figure out a way to let users blend in colors to make it...
