CrystaLac Grande Finale Tumbler Coat (Gloss, 12oz) 2.0

CrystaLac Grande Finale Tumbler Coat (Gloss, 12oz) 2.0 is a brush-on, self-leveling clear finish that creates a durable, glossy coating for tumblers when applied over prepared surfaces.

This high-gloss final coat is formulated for use on prepared stainless steel, plastic, ceramic and glass tumblers to give a smooth, protective sheen. It’s designed to self-level as it dries, dries to touch in about two hours between coats, and hardens fully over days. This version is non-toxic, non-hazardous and engineered to resist yellowing, with straightforward cleanup and safe indoor use when applied according to directions.

How should I prepare my tumbler before applying Grande Finale?

Preparation is crucial: remove any existing factory coating by sanding or chemical stripping, then clean the surface of dust and oils. Plastic, ceramic and glass always require sanding to ensure adhesion; stainless steel may also benefit from light scuffing. Proper prep helps the finish level and bond evenly for a long-lasting result.

• Sand or strip off factory coatings thoroughly.
• Wipe with a lint-free cloth and solvent if needed to remove oils.
• Use tack cloth or compressed air to remove sanding dust.
• Work at room temperature (68–78°F) for best results.

What’s the application process and dry time for this gloss coat?

Apply with a brush in thin, even strokes and allow approximately two hours of drying time between coats; the formula self-levels as it settles. Avoid over-brushing—apply and let it flow to eliminate brush marks. Do not speed up curing with heat guns; the product cures gradually and reaches usable hardness over several days.

• Brush on thin, even coats; don’t overwork the surface.
• Wait 2 hours between coats at room temperature (68–78°F).
• Do not use heat guns to force drying.
• Light use typically after 5–7 days; full hardening over 5–30 days.

Is this safe for indoor use and how do I clean finished tumblers?

Yes—CrystaLac Grande Finale is formulated non-toxic and non-hazardous, making it safe for indoor application when instructions are followed. The cured surface is non-yellowing and can be cleaned gently with soap and water. Hand washing only is recommended to preserve the finish over time.

• Non-toxic, non-hazardous formula suitable for indoor use.
• Non-yellowing finish preserves clarity and gloss.
• Hand wash only with soap and water—no abrasive cleaners.
• Allow full cure before frequent handling or washing.

How durable is the Grande Finale gloss and when can I use the tumbler?

The gloss forms a protective, hardening layer that achieves usable hardness within a week and continues to harden for up to 30 days. While gentle handling is fine after 5–7 days, avoid rough treatment until the coating reaches stronger hardness. Proper surface prep and correct application significantly increase durability and longevity.

• Usable after 5–7 days; full cure up to 30 days.
• Durability improves with correct sanding and thin coats.
• Avoid impacts and abrasive washing during initial cure.
• Maintains gloss and resists yellowing over time.
