Why does my timber look patchy after the first coat?

If your timber looks patchy after the first coat of hardwax oil, don't worry—in most cases this is completely normal. Different parts of the timber absorb oil at different rates because timber naturally varies in density and grain. Once the second coat has been applied, the finish usually evens out beautifully.

Why does this happen?

Timber is a natural material and every board is unique. Even within the same piece of timber, some areas are denser while others are more porous. Knots, grain direction and variations in the timber all affect how quickly the oil is absorbed.

When you apply the first coat of Evolution Hardwax Oil, these differences become more noticeable because some areas soak up more oil than others. The result can be a patchy or uneven appearance that often surprises first-time users.

The important thing to remember is that this is usually a sign that the timber is absorbing the oil as intended—not that anything has gone wrong.

What should I do?

Allow the first coat to dry overnight before applying the second coat.

For timber floors, lightly sand the surface with a 220-grit screen before applying the second coat. This smooths away any slightly raised timber fibres and helps produce an even, silky finish.

If you're oiling furniture or benchtops, a very light sand with a fine abrasive is usually all that's needed if the surface feels slightly rough after the first coat.

The second coat provides a more even level of absorption and, in most cases, produces the rich, consistent finish you're expecting.

When should I be concerned?

Although patchiness is usually perfectly normal, occasionally it can indicate another issue.

You may need further advice if:
• Large areas remain wet or sticky long after the recommended drying time.
• Previous finishes weren't completely removed before oiling.
• Too much product has been applied.
• Contamination from waxes, silicones or other coatings is preventing even absorption.
