Poly-Glass 320 Coatings

The Poly-Glass 320 coating from NAPCO is a greener, VOC compliant coating that allows the customer to “shower in 2 hours” after you recoat their bathtub. With this product, you can advertise that you use eco-friendly bathtub paint with a fast turnaround time for your bathtub repainting and refinishing services.

The purpose of bathtub refinishing services, also known as bathtub resurfacing or reglazing, is to deep clean the surface of the bathtub and restore its look with the application of a new bonding solution, followed by one or more coats of the new finish, or bathtub paint. Refinishing and repainting the bathtub gives tubs a like new appearance for a faction of the cost of replacing the tub. If you repaint and recoat bathtubs as part of your services, our Poly-Glass 320 coatings make an excellent addition to your tub resurfacing kit.


People can buy DIY tub resurfacing kits from manufacturers like Sherwin-Williams that include bathtub paint, and these coatings are applied with a roller. However, these DIY solutions yield mixed results and the new finish will only last a few years. With our Poly-Glass 320 tub paint, you can guarantee your customers a quality, long lasting finish compared to DIY bathtub refinishing kits. The low VOC rating of our Poly-Glass 320 coatings is also a great advertising point. Poly-Glass 320 is legal and compliant with the government’s stricter volatile organic compound (VOC) regulation and much safer for the natural environment. Plus, you will be protected from the fines that you could receive using bathtub paint and coatings that are not VOC compliant.


In addition to the low VOC rating, our Poly-Glass 320 products have the following advantages:

Fast dissipating odor: Not only is the odor not as strong as in other bathtub paint, but it will dissipate much faster.
Impact resistance: This coating has 50% greater impact resistance than other bathtub coatings which will help it last longer.
High gloss: When applied correctly, this coating has higher gloss.
Dries to touch in 4-6 minutes: This coating dries to the touch within 4-6 minutes of application which makes the bathtub refinishing job faster and reduces the risk of dust and runs in the coating.
Fast drying: Because this coating dries so fast, you can remove the masking paper and caulk sooner.
Shower in 2 hours: Your customers will be able to use their shower after 2 hours of your service. This is a great selling point! If customers want to take a bath, they should wait until the following day.


Poly-Glass 320 coatings are ideal for refinishing bathtubs, sinks, tile surfaces, and countertops. The low VOC rating of our Poly-Glass 320 products has made them NAPCO’s fastest selling coatings in our 30 years in the industry. Professional bathtub refinishers can order supplies online or by calling NAPCO at (800) 888-1081.
