The hidden cost of over-applying paint in joinery manufacturing

As Teknos shows, paint costs represent a significant proportion of finishing budgets for joinery manufacturers and many businesses are actively looking for ways to improve efficiency without compromising finish quality or long-term performance

One area that’s often overlooked is that of paint consumption during application. In practice, many manufacturers are applying more paint than is required – often without questioning it.

Why over-application is more common than expected

Worn or incorrect spray tips, inconsistent pump settings, sub-optimal spray technique and low paint temperatures can all lead to film builds that are higher than necessary.

Excessive film thickness can result in:

• Higher paint consumption

• Longer curing times

• Increased risk of defects

• Variation in finish quality

How to identify if you’re using too much paint

Many manufacturers rely on visual checks alone. While experience is valuable, it’s not always sufficient. One simple measurement can quickly highlight inefficiencies: wet film thickness.

During application, operators should regularly use a wet film gauge to measure the thickness of the applied coating. It’s also good practice to check multiple areas of the joinery, as film thickness often varies across a single component. Comparing these measurements against the coating manufacturer’s recommendations will clearly indicate whether excess material is being applied.

Technical know-how applied on site

Reducing paint consumption is about applying technical knowledge in real production environments. When Teknos’ technical experts visit joinery manufacturers, they provide on-site support by:

• Measuring wet film thickness

• Reviewing spray technique

• Identifying worn components, such as spray tips

• Optimising pump settings and application parameters

These practical steps can be implemented quickly and often deliver immediate results.

When film build is brought back within the optimal range, manufacturers typically see:

• Reduced paint consumption per component

• More consistent finishes

• Faster curing times, particularly noticeable during colder months

Importantly, correct application also ensures coatings perform as designed throughout their full service life, delivering the expected protection and appearance.

Why close collaboration matters

Teknos believes these improvements are most effective when technical support is delivered on site, in close collaboration with operators.

Working this way allows technical experts to see what’s actually happening in the spray booth, rather than relying on assumptions or remote troubleshooting. This approach helps identify small process changes that can have a significant impact on cost, quality and long-term performance.
