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.

Easy application

East to use but 32 oz does not cuver very much.

Use a paint or solid color stain over patched area

Would Recommend

Easy to work it into the rotted areas. Dries firm. Used this product to restore all the rotted areas on my deck after pressure washing. Areas treated with a wood hardner first then filled with the Platinum patch, easy to mold with putty knives to the contour of the boards. Stained with a semi-solid stain that did not cover well on the patched areas. Next time will use a solid color stain.

Excellent results

Used the product from the tub, not the tube, and achieved excellent results filling various gouges and holes in exterior wood siding. As one reviewer mentioned, once cured it can be difficult to sand. I did one side of the house two years ago and the areas where Platinum Patch had been used have held up perfectly.

Great stuff

Would Recommend

Used as a leveling compound over OSB and plywood. Nice fine compound. Easy to feather in. Readily adheres to both surfaces. Sets up quick. Easy to sand and paint. Though its a couple bucks more than the cheaper Flexible patch it fills at least twice the area compared to the gritty inferior Flexible patch - which does not feather because of the sharp, gritty sand filler.

Best Exterior Spackling Ever

Would Recommend

This product is the best I have ever used for extending the life of wood decks, steps and handrails that have developed cracks ( both on the surface and the ends and sides , like the edges of hand rails and the ends of balusters that catch water) but are still structurally sound. I apply one coat of my solid latex stain to act as a primer, then I use a flexible 4" putty knife to work it into the cracks and scrape it off flush. It isn't always necessary to sand after it dries but sanding can make...

Worth the cost over lesser priced products

Would Recommend

Nice consistency if container kept well closed. Drys hard, yet sands relatively easily.

Good Spackle Patch

Would Recommend

Decent filler product. Unsure how it will do in exterior applications, but holds its form well. Requires overnight drying time.

Great for ALL patching needs

Would Recommend

Outstanding for patching outdoor materials. I have patched cracks & holes in hardboard, filled holes in concrete, sealed crevices where bugs could enter and even patched holes in my fiberglass fountain bowls. I now use Platinum Patch for all indoor patching and spackling.

multi-purpose

Would Recommend

This is a great product indoor and out. I use it for all types of indoor trim. It is great to fill any voids, joints that are not perfect, and nail holes. I would say it is easy to sand, and if it gets a little thick, add a little water. I prefer it a bit on the looser side and have not been disappointed. I have used it on dry wall to patch holes. It makes them invisible. Can't go wrong.

Tube too difficult to squeze

Would Not Recommend

In frustration I cut open the tube to gain easy, efficient access to the spackle. If as in a previous comment the manufacturer claims "old shelf life" then I would suggest " use by " date on the tube. Would not buy the tube ever again.

Oh heck yes

OK for small repairs.

Would Not Recommend

Works ok on small cracks and depressions, but cracks on deeper holes even when you layer it up.

The patch was not in the stores so I ordered.

Would Recommend

This patch is easy to work with and cleans up with water. I hope the patch will be durable on exterior house siding.
