Dot and dab plasterboard is commonly used in modern homes and renovations, but it often raises questions when it comes to tiling. Many homeowners ask whether tiles can be fixed directly to dot and dab walls — and the answer depends on several important factors.
At Wrighte Tiling, we regularly assess dot and dab walls across Worthing and West Sussex to determine whether they’re suitable for tiling or if additional preparation is needed.
What Is Dot and Dab Plasterboarding?
Dot and dab is a method of fixing plasterboard to masonry walls using adhesive “dabs” rather than full plastering. It’s a fast and cost-effective way to create smooth internal walls, especially in modern builds.
However, because the plasterboard isn’t fully bonded to the wall behind, voids can exist between the board and the masonry — and this plays a major role in whether it’s suitable for tiling.
Can You Tile Directly Onto Dot and Dab Walls?
In some cases, yes — but only under the right conditions.
Tiling directly onto dot and dab walls may be suitable if:
-
The plasterboard is firmly fixed with no movement
-
The tiles are lightweight (such as ceramic wall tiles)
-
The wall is not exposed to excessive moisture
-
The correct adhesive is used
However, heavy tiles or natural stone can place too much stress on the board, leading to movement, cracked grout, or tiles coming loose.
Common Problems with Dot & Dab Tiling
When dot and dab walls are not prepared correctly, several issues can arise:
-
Hollow spots behind tiles
-
Cracked grout or tile edges
-
Tiles becoming loose over time
-
Water ingress in bathrooms or kitchens
These problems often occur because the wall lacks sufficient support or moisture protection.
When Extra Preparation Is Needed
In many cases, additional preparation is the safest approach. This may include:
-
Removing plasterboard and installing cement tile backer boards
-
Adding mechanical fixings through the boards into masonry
-
Applying waterproof tanking in wet areas
-
Strengthening the wall where heavy tiles or fixtures are planned
These steps ensure the wall is strong enough to support tiled finishes long term.
Dot & Dab Walls in Bathrooms and Wet Areas
Bathrooms require extra care. Standard plasterboard is not suitable for areas exposed to water, such as showers or bath surrounds.
For these areas, professional preparation may involve:
-
Removing existing plasterboard
-
Installing moisture-resistant or cement-based boards
-
Fully tanking the surface before tiling
This approach dramatically reduces the risk of moisture damage behind the tiles.
Professional Advice Makes the Difference
Every wall is different, and what works in one property may not be suitable in another. At Wrighte Tiling, we assess each surface individually and recommend the safest, most durable solution based on the type of wall, tile choice, and room use.
