Remove Equipment: Remove all removable parts, including the pump, control box, and tubes.
1
Drain and Clean: Drain the water and scrub the interior with a sponge, focusing on areas where paint is peeling or flaking, to remove as much old/degraded paint as possible.
1
Initial Drying: Wipe down the tub to remove excess moisture and leave the tub fully open to air-dry.
1
Final Drying (2–3 Weeks): Check every 12–18 hours for water settled in low spots and wipe it away. Allow up to 2–3 weeks of drying time, if possible, for optimal results. Rushing this step can lead to poor paint adhesion.

2. Surface Preparation and Protection
Decide on Sanding (Optional): Evaluate if the existing paint is too glossy for a new layer to adhere well or if it is flaking/chalky. If needed, sanding will roughen the surface and help remove loose paint.
1
Protect Surrounding Areas: Use masking tape and specialized masking tape with a plastic sheet attached to protect the freezer exterior from dust and paint splatter.
1
Sand the Interior (If Necessary):
Wear safety gear, including a respirator, goggles, and gloves.
1
Use coarse sandpaper to lightly roughen the surface and remove loose paint. Change the sandpaper often, as epoxy residue will clog it quickly.
1
Clean Up: Vacuum thoroughly to remove dust, then wipe down surfaces with thinner on a towel to remove residual powder. This step is crucial, as any residual dust can ruin a fresh paint job.

3. Paint Application
Prepare the Area: Protect the floor under the paint buckets and roller tray.
1
Mix the Paint:
Measure out equal parts of Part A (20 oz.) and Part B (20 oz.) for a total of approximately 40 oz. for one generous coat.
1
Combine them in a larger bucket and stir for at least 3 minutes until you have a uniform color and consistency.
1
Transfer the mixture to a paint tray.
1
Apply the Paint:
Load the roller until fully saturated and apply a generous layer to the tub interior. Aim for consistent, even strokes and avoid oversaturating the roller to prevent drips.
1
Use a brush to retouch corners, edges, or crevices the roller couldn’t reach.
1
Optional Second Coat: Wait 24 hours for the first coat to dry, then repeat the mixing and application process with a second coat for extra durability.
1
Remove Protection: Remove all tape and masking film once you are satisfied with the paint job. It should not stay on for over 4 days. Use paint thinner to clean any residual adhesive.

4. Curing Time
 
Allow 5 full days for the paint to cure and harden before reinstalling the liner or any equipment.
