Installation Methods for Engineered Oak Plank and Herringbone Floors

Gluing Down

Engineered Oak Plank and Herringbone floors can be glued directly to:

• Concrete
• Ceramic tiles
• Terrazzo
• Metal
• Slate
• Marble
• OSB
• Plywood

Ensure the existing surface is rough or porous. Pre-sand any slick or sealed surfaces, especially gypsum and anhydrite screeds, to remove the soft surface laitance.

Special Considerations for Gluing to Concrete

• We recommend using a Surface Primer to ensure a strong bond between the subfloor and adhesive.

Special Considerations for Gypsum or Anhydrite Screeds

• Additional preparation is required, including the removal of the soft surface laitance and refinishing with a primer and levelling compound.

Floating

A floating floor can be installed over:

• Concrete
• Anhydrite
• Existing wood floor
• Chipboard
• Ceramic tiles
• Terrazzo
• Metal
• PVC
• Linoleum
• Slate
• Marble
• Particleboard
• OSB
• Plywood

(Note: Floating floors cannot be installed over carpet.)

The type of underlay needed depends on the subfloor condition. However, for most installations, we recommend using an underlay with a built-in damp-proof membrane.

Additional Notes

• Plank Floors: Suitable for floating, secret-nailing, or gluing down.
• Herringbone Floors: Typically glued down but can be floated under the right circumstances.

Always refer to the manufacturer's fitting guides for the appropriate installation method.

Frequently Asked Questions about Oak Engineered Floors

How do I clean this floor?
To clean your oiled or lacquered floor, always follow the manufacturer's recommended cleaning procedures. Alternatively, you can use a well-wrung mop with water only. We do not recommend using a steam mop or any other cleaning solutions on our floors.

Does my floor need to acclimatise before installing?
Yes, we recommend letting your floor acclimatise for 3 to 4 days before installation. This should be done in the same room where it will be installed, and the flooring should remain in its sealed packaging to prevent warping due to temperature changes. Avoid storing the flooring outdoors, in outbuildings, or in areas with damp or condensation issues.

How much wastage do I need?
We generally recommend accounting for 10% wastage for plank floors, and 15% for herringbone. However, factors such as room shape and laying style can impact this, so always consult with your installer first.

What condition should the subfloor be in?
The subfloor beneath your oak engineered floor must be in good structural condition, free from damp rot, fungal or insect infestation, and contaminating residues. It should be flat, with uneven areas not exceeding 3mm over a 2m area. The surface should be vacuumed and completely free of debris before installation. Ensure hot pipes are well insulated to prevent localised hotspots, which can cause the wood to warp or shrink.

What is colour variation and how should I lay the planks with colour variation?
Colour variation refers to the natural differences in colour that occur in real wood. To achieve a balanced look, blend planks from several packs across the entire room.

What type of joints does this flooring have?
This flooring features Uniclic joints.

What expansion gaps are needed?
Wood naturally expands and contracts with changes in temperature and humidity. When fitting a wood floor, leave expansion gaps wherever the boards meet a wall, structural support, stairs, breakfast bar, fireplace, or central heating pipe. Gaps must also be considered at doorways to allow for differing expansion between rooms. Use spacers at regular intervals when fitting and remove them before installing skirting boards, beading, or trims. Allow a 2mm gap for every metre span of the floor, with a minimum of 10-15mm gap regardless. For areas over 5m in width, extra provisions should be made for expansion.

Can I have underfloor heating with this flooring?
Yes, this flooring is suitable for underfloor heating. Please refer to the manufacturer's installation guide for the appropriate installation method.

What does 'pack includes cut lengths' mean?
This means that at least one plank within your pack will be cut in half. This is intentional to help spread the joints out across your floor, preventing weakening. The other planks will be of the same length.

Can I use this flooring in my bathroom?
We generally do not recommend using engineered flooring in bathrooms or wet rooms. For waterproof options, consider products specifically designed for high-moisture environments, such as Click LVT.
