Painting Tiles in London Kitchens and Bathrooms: What You Need to Know

Painting Tiles in London Kitchens and Bathrooms

Tile painting is one of those projects that attracts a lot of interest but also a lot of scepticism. Done properly with the right products, it can produce a durable, attractive finish that transforms a tired kitchen or bathroom without the cost and disruption of a retile. Done poorly, it peels within months and looks worse than what it replaced. The difference between the two outcomes is almost entirely in the preparation and the product choice.

This guide covers what you need to know if you are considering painting tiles in a London property.

When Tile Painting Makes Sense

Tile painting is worth considering in the following situations:

• The tiles are in good structural condition but the colour or pattern is dated. 1980s terracotta tiles, pale avocado green, or the ubiquitous cream splashback tile all respond well to painting if the tiles themselves are intact.
• The grout lines are not heavily stained or damaged. If grout is crumbling or deeply discoloured, painting over it will not produce a clean result. Regrouting before painting, or accepting that grout lines will remain visible through the paint (which many paint systems accommodate), is the better approach.
• The budget does not allow for a full retile and a temporary or medium-term solution is acceptable. A well-applied tile paint system can last five to eight years in a bathroom and somewhat longer in a kitchen splashback area.
• The tiles are flat-glazed rather than textured. Heavily textured or relief tiles are harder to coat evenly, and the effect can look uneven.

Tile painting is less suitable where tiles are cracked, where there is significant movement in the substrate, or where the area is subject to very heavy water exposure such as directly inside a shower enclosure.

Tile Primer: The Critical First Step

No tile painting project should skip the primer stage. Standard primers do not bond to glazed ceramic surfaces; you need a specialist tile primer or adhesion promoter. Good options include:

• Zinsser Bulls Eye 1-2-3 -- a water-based primer with strong adhesion to difficult surfaces including glazed tiles, available in white and grey tints
• Rustins Tile Primer -- an oil-based primer specifically developed for ceramic tiles, giving excellent adhesion for subsequent coats
• Dulux Trade Tileguard -- part of a dedicated tile paint system that includes primer and topcoat formulated to work together

The primer coat should be applied thinly and evenly, ensuring full coverage of every tile surface without runs or pooling in grout lines. Allow the full recommended dry time before topcoating; rushing this stage is one of the most common causes of adhesion failure.

Topcoat Systems for Tiles

Once primed, the choice of topcoat determines the durability and appearance of the finished result.

Dedicated tile paint products (such as the Rust-Oleum Tile Transformations kit or Ronseal One Coat Tile Paint) are formulated to be harder and more moisture-resistant than standard wall paints. They are typically available in a limited but practical palette of whites and neutral shades, and they are the most straightforward option for a DIY or trade application.

Two-pack epoxy or polyurethane systems offer significantly higher durability and are used by trade decorators for commercial kitchens and bathrooms, or for domestic projects where longevity is the priority. These products require careful mixing, have a limited pot life once mixed, and have higher VOC content, requiring good ventilation. The finish is extremely hard and resistant to moisture, steam and cleaning products. Two-pack systems are the specification we most often use in London properties where the kitchen or bathroom sees heavy use.

Chalk or mineral paints are sometimes suggested for tiles, and while they adhere reasonably well to primed surfaces, they are not recommended for wet areas. They are porous and will absorb moisture and cleaning product residue.

Preparation in Detail

The preparation sequence for tile painting:

1. Clean thoroughly with a proprietary degreaser or a strong solution of sugar soap. Kitchen splashback tiles accumulate cooking grease that is invisible to the eye but will prevent primer adhesion. Bathroom tiles accumulate soap scum and limescale.
2. Sand lightly with 120--180 grit wet-and-dry paper to key the glaze surface. This is not strictly necessary with all primer systems but improves adhesion meaningfully.
3. Inspect grout lines and repair any that are crumbling or missing. Allow repair grout to cure for at least 48 hours before priming.
4. Mask and protect carefully. Tile paint on sanitary ware, baths, basins or worktops is difficult to remove without scratching the surface.
5. Apply primer in thin, even coats.

Colour Choices

The practical colour range for tile painting is narrower than for wall painting because the hardest and most durable topcoat systems are typically available in white, off-white and light neutral shades. Custom colour matching is possible with two-pack systems at additional cost. For most kitchens, a clean white or warm off-white splashback is the most versatile choice; it reads as fresh, suits multiple kitchen colour schemes and shows less wear than darker tones over time.

Durability Expectations

Be realistic about what tile paint will and will not achieve. With proper preparation and a quality product:

• Kitchen splashbacks: five to eight years is a reasonable expectation before repainting is needed
• Bathroom walls in a family bathroom: three to six years, depending on cleaning regime
• Shower enclosures: tile paint in direct shower areas often fails within two to three years even with the best products; full retiling is the more reliable solution for shower interiors
