Glad to lend a hand. You'll need to sand the surface be applying the Rust-Oleum Specialty Chalkboard Spray to ensure the best adhesion, but a primer will not be necessary. - Rust-Oleum Product Support 5
Usually its the paint color.
Good Question Mike! Rust-Oleum Specialty Chalkboard Spray Paint converts a variety of indoor surfaces into a usable chalkboard, this is for indoor use only. If you're looking for a flat black spray paint for outdoor use, we recommend Rust-Oleum Stops Rust Protective Enamel Flat Black Spray Paint. https://www.homedepot.com/p/Rust-Oleum-Stops-Rust-12-oz-Protective-Enamel-Flat-Black-Spray-Paint-7776830/100670370 - Rust-Oleum Product Support 6
Great Question LR! Rust-Oleum Specialty Chalkboard Spray Clear can be applied over Specialty Chalkboard Black, provided the surface is cleaned to remove any contaminants. If possible, test in a small area to determine what effect the clear may have on the chalk. Since paint adheres to whatever surface it is applied to, in the chalked areas the clear would not adhere to the original coating but to the chalk instead. - Rust-Oleum Product Support 6
Thank you for reaching out! Our Rust-Oleum Specialty Chalkboard Spray may be recoated within 1 hour, allowing 10-20 minutes between coats. If the previous coat has dried for more than 1 hour, we recommend allowing the coating to dry for at least 24 hours before applying the next coat. Once the Chalkboard Paint has dried for 24 hours, it is fully dry, and may be conditioned by rubbing the side of a piece of chalk over the entire surface and erasing with a chalkboard eraser. - Rust-Oleum Product Support 2
If the surface was previously painted, there will not be a need to prime before using Rust-Oleum Specialty Chalkboard Spray Paint. In the event that this was a bare surface, we'd suggest a primer such as Zinsser Bullseye 1-2-3 Water-Based Primer and Sealer. http://www.homedepot.com/s/bullseye%2520123?NCNI-5
We recommend starting off with an oil-based primer, such as Zinsser Cover Stain for proper adhesion of Rust-Oleum Chalkboard Paint to the corkboard surface. To help ensure an even writable surface, this product is recommended for use on a smooth surface. http://www.homedepot.com/p/Zinsser-1-qt-White-Cover-Stain-Oil-Based-Interior-Exterior-Primer-and-Sealer-3504/100398403
Thank you for reaching out, Liv! Rust-Oleum Specialty Chalkboard Spray Paint is suitable for use on paperboard. We recommend applying in a test area first to ensure the desired results.
Yes, Rust-Oleum Specialty Chalkboard Paint may be applied over an existing chalkboard surface. You will need to clean the surface thoroughly and prime with an adhesion promoting primer such as Rust-Oleum Zinsser Bulls Eye 1-2-3 first. Chalkboard paint will not adhere directly to a slate surface on its own without the primer. http://www.homedepot.com/p/Zinsser-Bulls-Eye-1-2-3-1-qt-White-Water-Based-Interior-Exterior-Primer-and-Sealer-2004/100398398
Yes. Rust-Oleum Specialty Chalkboard Paint may be applied to metal, wood, plastic, hardboard, glass or paperboard. Keep in mind smooth, hard, or glossy surfaces should be scarified by sanding to create a surface profile for best adhesion of the paint. We recommend 180-220 grit sandpaper.
