Tub, Shower, & Tile Refinishing Coating Additives

The Best Bathtub Coating Additives on the Market


We have a bathtub refinishing additive for any coating and job.


Use NAPCO’s coating additives to enhance the performance of our bathtub refinishing coatings. For a fast cure time, our popular Accelerator is used to reduce the chance of runs and dust contamination and is especially useful for colder weather. On the other hand, our Retarder is useful in warmer weather to slow down the drying process.


When you need an edge on a hard-to-spray surface or need to combat hard-to-spot contaminants, use NAPCO’s Fisheye Eliminator for a smooth, professional finish. And if a nonslip surface is what your customer is looking for, just roll or brush on NAPCO’s Anti-Slip Solution or add our Anti-Slip Granules to the topcoat of your choice.


At NAPCO, we also offer Scented Additives to mask unpleasant tub and tile refinishing odors and Poly-Glass Color Dispersions to provide color matching for a full refinish job or spot repair.


Professional bath and kitchen refinishers can order supplies online or call us at 800-888-1081.

What Refinishers Have to Say About NAPCO’s Tub & Tile Refinishing Coating Additives


Review by Michael Marciano – Rochester, NY


Rating 5 5 Star Rating

My name is Michael Marciano and I've been refinishing bathtubs & tile for 8-years. Over that time I've experimented with multiple different coating providers such as Hawk Coatings, Shark Grip, Top Coat, Rustoleum, European Coatings, and NAPCO. Some coatings being more cost effective then others, some more convenient to purchase / acquire, but at the end of the day the 4-hour cure, customer service, work ability of their coating has concreted NAPCO as my only chemical provider moving forward.
The trade in program offered by NAPCO is a great resource for any refinisher on the fence about switching to NAPCO full time, they took all of my remaining competitor coatings and gave me more then a $1,000 in product to replace the aging coatings on my shelf and remove the thought of using a competitors product.
Thank you once again Larry for you great customer service and letting an existing customer utilize this program.

Rating 5 5 Star Rating

We have been using Napco products for about 1.5 years now. Napco products have always exceeded our expectations. We primarily use their 320 Product lines. After we depleted our stock of their Poly Tub & Tile Prep we ordered their new tile preparation product (Piranha Prep). The Piranha Prep is a concentrated solution that cleaned the tubs very well without those harsh chemical odors.
So, on the behalf of Richardson HomeWorks LLC, we thank you for such an amazing Tub and Tile Prep.

Bathtub, Shower, & Tile Coating Additives FAQ

How do NAPCO’s bathtub and tile coating additives work?

NAPCO carries a wide variety of coating additives for different purposes. For example, accelerators speed up the curing process (useful for colder weather) while retarders slow down the curing process (useful for warmer weather). NAPCO also offer anti-slip solutions, scented additives to mask unpleasant refinishing odors, and color dispersions for color matching.

Who can order NAPCO’s bathtub, shower, and tile refinishing additives?

Due to the chemical nature and particular handling of many of our products, NAPCO does not sell to the general public. We are concerned for your safety and want to make sure you are educated on the products you are using. Prospective customers can contact us to see if they qualify to become a NAPCO dealer.

Does NAPCO offer tub and tile coating additive discounts for refinishers ordering large quantities?

Yes! Each customer is included in our NAPCO Loyalty Program to ensure they receive the maximum discount off of our already competitive prices. The more you purchase from NAPCO, the more money you save.
