Can't stand the colour of your kitchen tiles or the dated style of your bathroom anymore? Going the demolition route takes time, creates a lot of dust and means a significant budget.
Fortunately, the paint-on-tiles trend now lets you revamp wet rooms in record time. However, to succeed with tile paint, there is one major pitfall to avoid: leaving the visual imprint of the old hollow joints.
Discover how Prisma Color Tile Coating turns your textured surfaces into perfectly smooth walls, ready for your new finish.
The secret of a successful bathroom tile paint job
When you apply bathroom tile paint directly onto old tiling, the relief of the joints often stays visible under the paint film. The result lacks elegance and reveals the old tiling.
To get a "brand-new wall" effect, surface preparation is key. And if the wall behind the tiling is soaked, start by treating the wall’s humidity upstream: a healthy surface is the basis of a lasting renovation.
Discover Prisma Color Tile Coating: an ultra-high-performance paste formula
To meet the demands of modern renovation sites, Prisma Color developed a superior technical product designed to make preparation easier.
Prisma Color Tile Coating is a ready-to-use paste coating that smooths out irregularities and covers old tiling with ease. Its advantages are many:
- Very high-build formula: its rich consistency fills deep hollows in a single pass.
- Zero defects: it does not crack when filling joints nor crackle when drying, ensuring a perfectly stable surface for your future tile paint.
- Watertight, durable grip: it offers excellent adhesion on smooth surfaces and resists the humidity of wet rooms remarkably well.
Preparation and application guide for Tile Coating
Step 1: the first coat and filling. First make sure the old tiling is perfectly degreased, clean and dry.
- Apply the first coat of Tile Coating with a filling knife while filling the joints.
- This technique fills the gap between tiles and creates a first even base.
Step 2: drying and finishing. Let the surface dry, then after 6 hours apply the second coat to set the flatness.
- The second pass smooths everything and removes the last reliefs.
- After full drying (and light sanding if needed), your wall is transformed.
All that’s left is to apply your favourite tile paint, using Prisma Color’s wide decorative range: Vega Star, Chromia, Onyx or Iridium.
And since the bathroom is naturally a humid room, remember to protect wet rooms with an anti-mould paint to preserve your new finish for the long term.
