Step-by-Step Guide

How to Use the NGlazeSystems Kit

Restoring a bathtub is a DIY project that you can successfully complete yourself. To achieve excellent results, follow every step of the process meticulously—this is the most critical part of the job.

Key Point: Room Temperature

The room temperature in the bathroom must be kept within the range of 65–80°F (18–27°C). This ensures correct chemical bonding.

Working Time Limit

Once Parts A and B have been mixed, you will have approximately two hours to complete the work before it begins to cure.

Surface Preparation and Cleaning

First, remove all old silicone or sealant from around the bathtub. Scrape away any peeling paint or remnants of the previous coating using a scraper.

Next, use a drill fitted with a wire brush attachment to thoroughly clean the drain opening and the overflow plate opening.

Repairing Damage (Chips and Cracks)

For a flawless finish, it is essential to fill in all surface damage. This can be done using a two-part epoxy putty or filler.

Once dry, sand the repaired area until it is smooth and flush with the surrounding surface.

Surface Preparation and Sanding

Sand the entire surface of the bathtub. This creates a microscopically rough surface to which the epoxy coating can firmly bond.

Grit Recommendations:

80–100 grit sandpaper for cast iron or steel tubs.
180–220 grit sandpaper for plastic or acrylic tubs.

Drying and Degreasing

Thoroughly clean the bathtub using an abrasive cleaner (such as Ajax or Comet) to remove all soap scum and grime. Wipe away any residual water using paper towels, paying special attention to the corners; then, dry the bathtub completely using a hairdryer.

Wipe down the entire dry surface of the tub with a degreasing agent, such as 91% isopropyl alcohol or acetone.

Finally, use painter's tape to secure a plastic cup over the faucet to prevent any water drips from falling onto the surface during the coating process. Mask off the drain, the overflow opening, and the surrounding walls adjacent to the bathtub using painter's tape.

Mixing

Pour the entire contents of Part B into Part A, then stir slowly and thoroughly with the mixing stick for at least 8–10 minutes.

Begin by pouring the mixed enamel onto the upper edges and walls of the bathtub. Use the included plastic spatula to spread the enamel evenly over the walls.

Finishing

Pour the remaining enamel onto the bottom of the bathtub. Using the notched trowel, level the remaining material across the bottom of the tub to a thickness of approximately 1/16 inch.

Note: Since the drain is the lowest point of the tub, any excess material will flow toward it; this excess must be removed.

Remove the painter's tape exactly 2 hours after mixing the enamel. Allow the bathtub to dry for 24 hours before use.

7. Bathtub Care

Your new NGlazeSystems coating can last for many years. The key is proper maintenance. You may use any cleaning agents that do not contain chlorine or ammonia. For cleaning, use only mild, non-abrasive products (e.g., Lysol).

🚫 Avoid harsh chemicals, drain cleaners, or abrasive sponges.
