How dot and dab wall lining works
The method uses a specified adhesive arrangement to fix suitable boards to a suitable background. It creates a board face that then receives the agreed finish. The familiar name does not describe every product or detail in the system, so confirm exactly what is being proposed.
Check masonry suitability
Background condition is central. The manufacturer's system requirements must be met, and damp or loose material should not simply be covered. An existing plastered surface may need assessment and preparation; masonry that looks straightforward can still require checks before direct bonding is suitable.

Allow for lining depth and fittings
The lining changes where the finished wall sits. Window reveals, door edges, sockets and skirtings need coordinating with that new face. Identify planned cupboards or other fixtures early so the fixing approach can be considered rather than improvised after the wall is finished.
Board installation and final finishing
Board fitting, joint treatment and skimming are distinct parts of the package. Ask which are included and what condition the surface will be handed over in. Decoration and service alterations may sit outside the boarding scope even when they are needed to complete the room.
Compare the complete dot and dab scope
Compare the full installation, not just the board area. Include background preparation, reveals, perimeter details and waste. If insulation is the objective, use a specified insulated lining approach rather than assuming any direct-bonded board will provide the improvement you have in mind.
PRACTICAL SERVICE DETAILS
Common questions
Is dot and dab suitable for every masonry wall?
No. The specified system needs a suitable background and site conditions. The wall should be assessed rather than choosing the method only because it is masonry.
Can it be used over existing plaster?
It may be possible on suitable sound backgrounds within the system requirements. Existing coatings, adhesion and moisture condition need checking.
How are fixtures planned on the finished wall?
State the intended fixtures before installation. The appropriate fixing and support arrangements depend on the lining and the loads involved.
Is a skim included in the boarding quote?
Only if specified. Ask whether the quote includes boards, joint preparation, skim and decoration, and clarify any excluded stage.
