A: Happy to help, Robert! Rust-Oleum Zinsser Ready Patch Spackling and Patching Compound cures to a very hard, inflexible finish, and is not the best choice for flexible materials such as PVC or vinyl. A flexible caulk or filler for vinyl and PVC is a better option for this type of project. - Rust-Oleum Product Support 3
A: Try dipping your tool into water before applying Ready Patch on the tool. Also use some foam filler in the hole. You won't use as much Ready Patch.
A: Thanks for reaching out. Zinsser Ready Patch Professional Spackling & Patching Compound is a full-bodied product that is durable enough for your most heavy-duty repairs. We recommend using a 1" or 2" putty knife to fill nail holes, cracks or larger gouges. Spread Ready Patch over the hole and remove excess with the putty knife until product is smooth and flush with the surface. Apply as many coats as necessary to fill the hole or imperfection level with the surrounding surface. If holes are wide and over ¼” deep, two or more applications are recommended. - Rust-Oleum Product Support 6
A: It would depend on how wide the holes are. I've used this product quite a bit and it works well. Depending on how deep the holes are, don't try to completely fill them with one application. Most siding is 5/8 to 3/4" think so it might take a couple of applications.
A: Likely more of an issue with trying to do too much at one time. I would try to do a gross application and sand when it is dry. Then reapply to get a smooth top coat, followed by sanding. It drys relatively fast but it will need more time if it is a big hole. Better to do multiple layers. Been using this stuff for years. Works great!
A: The person you should be asking,is the people that made the product. I can't answer your question for you.
