How to Avoid Coating Issues When Applying Polyurethane to Timber Floors

For flooring professionals, the right polyurethane finish is critical to delivering timber floors that look stunning and stand the test of time. But mistakes in product choice or application can cause streaks, peeling, yellowing, and premature wear—leading to costly repairs, unhappy clients, and damage to your reputation. At Handley Industries, we believe flawless finishes start with proven products like Handley Omni~ water-based polyurethane and the right preparation strategy.

The 5 Most Common Polyurethane Coating Problems — and How Handley Omni~ Helps Solves Them

1. Inconsistent Sheen and Streaks

Problem: Poor leveling can leave unsightly lap marks or uneven shine.
Handley Solution: Omni~’s self-leveling formulation ensures an ultra-smooth finish, reducing streaks even on large areas. For best results, apply with a quality 6–10 mm nap roller and keep a wet edge at the recommended spread rate of 8–10 sqm/L. Using a sealer on tannin-rich timbers also reduces lap marks and picture framing.

2. Peeling or Poor Adhesion

Problem: Coatings can lift when applied over poorly prepared surfaces or incompatible finishes.
Handley Solution: Omni~ adheres strongly to properly sanded timber (minimum P150) and can even be applied over existing coatings with correct surface prep—saving time while ensuring long-lasting performance.

3. Yellowing Over Time

Problem: Solvent based aromatic polyurethanes often yellow, distorting light timbers.
Handley Solution: Omni~ is a 100% polyurethane polymer dispersion designed to stay crystal clear and non-yellowing for years—preserving timber’s natural tone.

4. Bubbles or Pinholes

Problem: Overworking with rollers, or drafts can trap air in the finish.
Handley Solution: Shake Omni~ gently and apply with light, steady strokes. Its excellent wet-edge and leveling properties further reduce trapped air.

5. Extended Drying or Curing Times

Problem: Slow-drying products can stall your schedule, especially in humid or cool conditions.
Handley Solution: Omni~ dries quickly—4–8 hours per coat—allowing multiple coats in a single day.
