GUIDE / SURFACE PREPARATION

What new kitchen finishes sit on.
Check the layers before the surface.

A new benchtop, splashback or floor is only as sound as what it is fixed to. If you replace the visible finishes before checking moisture, substrate suitability, service access and underlying damage, you can end up with rework that could have been avoided. This guide walks through each layer Ivan Bodnar looks at during an on-site assessment of a Murrumbeena kitchen, and explains why the right scope depends on that inspection.

SHEET / LAYERS

What new finishes sit on

Checked from the bottom layer up, before any new material is chosen.
01

Moisture

Water from around the sink, dishwasher and fridge can find its way into cabinet bases, wall linings and flooring. If a new finish goes over damp material, the problem is trapped underneath, not fixed.

02

Substrate suitability

The wall, floor or carcass underneath has to suit the new material. Old adhesive, loose sheeting or an uneven floor at the kickboard all change how much surface preparation the job needs.

03

Service access

Pipes, drains and power often run behind the base cabinets. If a new layout or appliance means they have to be moved or reached, that needs to be planned before new finishes close them in. Any regulated work goes to licensed trades.

04

Underlying damage

Swollen particleboard, soft wall linings and old patch repairs often show up only once cabinets and splashbacks come off. More on this in what may be found behind kitchen cabinets.

05

The visible finish

Choosing a benchtop, splashback, door style or floor only makes practical sense once you know what’s underneath. The materials should be chosen to suit the prepared surface, not chosen first.

A tradesperson wearing a cap and protective clothing applies sealant or caulk around white cabinetry or window trim in a kitchen renovation workspace, with nearby surfaces covered in protective plastic.

WHERE REWORK COMES FROM

Finishing first, then finding the problem

Rework tends to happen the same way each time. A splashback is tiled onto a wall nobody checked. A new floor is laid over an uneven subfloor. New cabinets go in above a sink base that has had a slow leak. The new surface looks fine for a while, then it has to come off again so the real problem can be fixed.

Checking first doesn’t always mean a bigger job. Sometimes the inspection shows that the existing cabinets or the current layout can stay. For the details, see reusing kitchen cabinets and keeping your existing layout. Either way, the decision is based on the condition of your kitchen.

LIMITS OF AN INSPECTION

If something turns up once work begins, Ivan explains what it is and the practical options, so you can decide how to go ahead.

What an inspection can and cannot tell you

An on-site assessment cannot reveal every concealed issue. Some conditions only appear once cabinets, splashbacks or floor coverings are removed. Project scope, permits, registration, insurance and licensed trade requirements also vary from kitchen to kitchen. Contract, insurance and approvals wording is verified for each project.
