About A-Prime Grade
A-Prime Grade is one of Timbo's five appearance grades for timber flooring. It is chosen for contemporary, minimalist and high-end interiors, and pattern floors such as herringbone and chevron where you want the pattern – not the knots – to be the feature.
Characteristics
- Few, if any, knots – a clean, uniform look
- Consistent colouring for a sleek, polished floor
- Smooth surface free from visible imperfections
- Timbo's highest appearance grade, selected for premium projects

Frequently asked questions
What does A-Prime Grade look like?
The cleanest, most uniform appearance – few if any knots and consistent colour. Because timber is natural, every batch varies slightly – ask for a free sample.
Is a lower grade weaker than A-Prime?
No. Grades describe appearance – knots, colour variation and character – not strength. See oak flooring grades explained.
Which grade suits herringbone or chevron?
Cleaner grades such as A-Prime and AB let the pattern itself stand out, which is why they're popular for parquet. More rustic grades give a characterful, aged parquet look.
