A leaking bathroom doesn't mean demolition. Paint straight over your existing tiles with a Polyurea engineered for permanently wet rooms — waterproofing built in, and you can do it yourself.
Ordinary paint peels off glazed tiles because it was never born for this job. TileCoat was born for exactly this job.
Skip the whole demolish-remove-haul-retile circus. Save time, save labor cost, and keep your bathroom out of service for hours — not weeks.
The same material class used in industrial waterproofing — it shrugs off the constant humidity of a wet bathroom.
The hardest problem in this game — and the one we spent the longest solving: a film that truly grips glossy glazed surfaces without peeling.
Not just a new tile color — you get a waterproof layer in the same coat, fixing the leak at its source for the long run.
R&D LOG — ORIGIN STORY
6YEARS OF R&D
Waterproofing is not ordinary paintwork — and painting onto glossy glazed tiles in a permanently wet bathroom is one of the toughest briefs in surface coating. Most paints hold on for a while, then repeated water and heat peel them off in sheets.
TileCoat Polyurea has been LucernaPro's product since the day the company opened. We reformulated, tested and collected results from real job sites for over 6 years until we had a Polyurea that grips glazed surfaces and survives wet bathrooms long-term — a formula proven not just in the lab, but in real customers' real bathrooms.
Ordinary paint won't stay on glazed tiles — a glossy surface is adhesion's true enemy.
Reformulate the Polyurea and test it against real wet conditions, again and again, until the film held under every one.
A tile paint with waterproofing built in that survives wet bathrooms — and remains our flagship to this day.

Genuinely DIY-able, all 6 steps
Scrub off soap scum, grease and algae, then let everything dry completely — a clean surface is half the battle against peeling.
Any grout that's chipped, missing or cracked must be fully repaired first — always. Skip this step and the waterproofing simply won't work.
Mix the two-part primer and coat the whole area — this step is the heart of adhesion on glazed tiles.
ผสม 2:1 · พัก 4–6 ชม. / Mix 2:1 · Rest 4–6 hMix Part A with Part B and paint into every corner and grout line. A thin, even film beats thick patches.
Part A : Part B = 2 : 1Let the first coat dry for 2 hours, then coat again — two coats give the film the thickness a waterproofing system needs.
รอแห้ง 2 ชม. / Dry 2 hAllow the film to fully cure, then use your bathroom as normal — job done without removing a single tile.
⚠ Not suitable for people allergic to thinner or chemical products — if you have such allergies, have a contractor do it. Always work in a well-ventilated space.
⚠ About slip resistance — straight talk: the paint contains anti-slip grit that adds real grip, but don't expect it to match rough-textured tiles — take care on wet floors, as you always should.

Most bathroom cleaners are strong acid. The short answer is yes, it holds up. The better answer: once coated, you barely need that stuff anymore.
One smooth, continuous film — tiles and grout sealed under the same layer, no pores for grime. Most stains wipe off with plain water or mild soap.
Stands up well to household cleaners. An occasional acid wash, rinsed with water afterwards, won't peel or lift the film.
Strong acid attacks every surface it touches. For the longest life, a regular pH-neutral cleaner does the job just fine.
