Floating vs Direct Stick Timber Floors: Which One’s Right for You?

Choosing between a floating floor and a direct stick installation isn’t just about price — it’s about how you want your floor to feel, perform, and last. Both methods have their strengths, and understanding the differences can help you make the right call for your space, your lifestyle, and your budget.

Floating Floors: Fast, Flexible, and Affordable

Floating floors are popular for good reason. They’re quicker to install, more cost-effective, and ideal for renovations or DIY-friendly projects. The boards are not glued down — instead, they “float” over an underlay, which provides cushioning, sound absorption, and moisture protection.

Here’s how it works:

• An underlay is rolled out across the subfloor. For timber and laminate, this underlay is separate and should be taped at the seams to seal out moisture.
• Hybrid floors come with the underlay already attached, making installation even easier.
• The boards are clicked or locked together and laid across the underlay — no adhesive required.
• Floating floors with T&G joint systems require a crosslinking adhesive to be applied to the joins (For details reach out to the Sunstar Technical Team)

Important: Floating floors must have a 10mm perimeter gap around all walls and fixed objects. This gap allows the floor to expand and contract naturally with changes in temperature and humidity. It’s hidden under scotia or skirting boards, but it must never be filled with adhesive or caulk. Blocking this movement can cause buckling or damage.

Direct Stick Floors: Solid, Seamless, and Built to Last

Direct stick floors are the premium choice. They’re glued directly to the subfloor, which gives a more solid feel underfoot and reduces sound transfer. They’re also easier to repair — individual planks can be cut out and replaced if damaged.

Here’s how it works:

• The subfloor is prepared and cleaned.
• Adhesive is applied, and the boards are laid directly onto the surface.
• The floor is left to cure — and this is where timing matters.

Key tip: In the first 48 hours, the adhesive is still pliable, so the boards can shift slightly. It’s crucial to leave enough space around the perimeter — at least 4mm — to accommodate this movement. If you plan to caulk the edges, use a flexible silicone and wait until the adhesive has fully set (after 48 hours).

Direct stick floors don’t move once cured, which means they don’t require expansion gaps like floating floors. But if you ever need to remove the entire floor, it’s a major job — costly and time-consuming. That’s why direct stick is often considered a “forever floor.”

Underlay Considerations

• Floating floors always require underlay unless it’s built-in (as with hybrids).
• Direct stick floors can be installed over rubber or cork-based underlays for added comfort or acoustic performance — but always check with the underlay supplier to ensure compatibility with adhesives and flooring type.

Pros and Cons at a Glance

Floating Floors

• Affordable
• Fast installation
• Easy to remove or replace
• Must allow for movement
• Slightly less solid underfoot

Direct Stick Floors

• Premium feel
• Quieter, more stable
• Individual plank replacement possible
• More expensive
• Difficult to remove once installed

If you’re after speed affordability and flexibility, floating floors are a great choice, if it’s a family home and in the next 18 years it’s going to see plastic scooters, footy boots then teenage parties, maybe work on it’s getting replaced at the end of that stage of the families life. If you want a floor that feels like part of the home’s foundation — and you’re ready to commit — direct stick is the gold standard.

Either way, the most important thing is that you love the look, and it fits your budget. The rest is just installation method.
