SEALER STRIPPER AND COATING REMOVER
Nock-Off is a high-performance industrial paint, coating and sealer stripper. Nock-Off easily removes even the toughest industrial coatings like epoxies and urethanes from all types of surfaces including concrete, pavers, metal, wood and more. Nock-Off is perfect for removing old mastic, concrete coatings, paver sealers and even hard to strip deck and fence stains!
Not only is Nock-Off effective, it is also much safer and easier to use than other strippers that contain dangerous, toxic or carcinogenic chemicals. Nock-Off is biodegradable, environmentally (and user) friendly, non-flammable and contains no dangerous carcinogens. Nock-Off is easy to apply by roller, brush or sprayer.

Nock-Off is one of the best coating removers we have ever used. Sure, you can find other products that work a little faster, but we just don't believe it's worth the risk of exposing yourself, your employees and especially your customers and their children to the toxic and carcinogenic chemicals found in many of the most popular products on the market. Not only is Nock-Off safer, it works great AND you can actually afford to buy it!
Nock-Off is VOC compliant, non-flammable and environmentally safe. It is highly effective in removing even the toughest and most durable industrial coatings such as urethanes and epoxies from surfaces like metal, wood, masonry, brick and especially concrete. Nock-Off even works great to remove the new, water-based, guaranteed to peel, garbage sold in the deck and fence stain aisle of your local home store! (Of course, once you get that stuff stripped off, give us a call for some real deck or fence stain)
Always apply to a test area before applying to entire area. This will allow you to estimate the dwell time required for project completion, prove the ability of the stripper to remove coating, ensure substrate compatibility, and show most effective method of removal.
Cover any adjoining or nearby surfaces not intended to be stripped. Plastic sheeting works well as a protective barrier. Masking tape is not recommended since stripper can soak through the tape and damage painted surfaces behind it. Plants and vegetation should be covered and washed thoroughly with water before and after application.
Mix thoroughly using a drill mixer. Mix Nock-Off until all product is uniform in color and of a creamy consistency. Do not shake to mix!
Apply a thick, even layer of stripper onto the coating to be removed. An airless sprayer has shown to be the best means for application. Always start the sprayer pump at the lowest pressure setting, and slowly build up the pressure until the proper fan pattern has been generated. High pressure and narrow tip sizes will break the stripper's emulsion and affect its integrity. Nock-Off should be applied at approximately 2 times the thickness of the coating being removed. When trying to build very thick films, or when trying to apply the stripper on a glossy or greasy vertical surface, it is recommended to apply the stripper via two separate applications. First apply a light coat of approximately 12-15 mils, thick enough to hide the surface color of coating and allow it to dwell for 15 to 30 minutes and then build the rest of the stripper film thickness in a second application.
When there are multiple layers of existing material, it may be possible that there is inadequate inter coat adhesion between some layers. Premature de-lamination may occur at this interface. If this happens, quickly remove the de-laminated layers and reapply the stripper. Do not rinse with water between applications. Do not allow the stripper to dry out. The stripper is designed to remain wet and effective over extended periods of time (up to 24-48 hours), however, excessive sunshine, windy conditions, or insufficient stripper thickness may cause early drying. Use plastic sheeting to cover stripper to minimize evaporation. If the stripper starts to dry, re-apply a light coat and allow an extended time frame for project completion.
The time required for adequate penetration tends to vary according to the type, the thickness, and the temperature of the coating. Most paint systems require between 2 to 36 hours. Nock-Off can be left overnight, but do not allow it to dry out. It is recommended to cover Nock-Off with poly sheeting to reduce the drying time and to allow adequate coating penetration.
If planning to re-coat, stain, seal or paint, follow all manufacturer's recommendations for cleaning and prep before application.
Coverage rates are approximate and will vary depending on coating type, substrate porosity and applicator.
