When installing any hardwood flooring or doors it is important that the conditions within the property are suitable.
We strongly recommend that the installation of hardwood flooring and/or doors should be one of the final works at your property to avoid any subsequent damage or dirtying of the products whilst other works are being carried out.
Load bearing flooring (i.e. 18mm thick or thicker) can be secret or face nailed to existing / new joists and or battens providing they are dry and sound. Each flooring product on this website has a section detailing whether it is suitable to be fitted onto joists / battens, please look out for this.
Most joists or battens are usually set at 400mm centres or less, a structural engineer can always confirm these details.
These products can also be fitted onto chipboard or existing timber flooring by nailing through to the joists beneath.
Secret nailing involves nailing at a 45-degree angle through the tongue of the flooring, usually this is done using a portanailer gun or similar device. If you are nailing by hand it is recommended pilot holes are drilled before nailing.
A suitable expansion gap should be left around the perimeter of the floor area and under doorframes. On a standard size room, i.e. up to 70 square metres, this is recommended as 15mm. For larger rooms, please call us for further advice.
This section refers to the gluing of flooring directly to the sub-floor, not gluing the boards for use as a floating floor (see floating floor applications).
Gluing solid floor boarding to sub-floors will always have an element of risk, as when the wood naturally shrinks and expands there is the potential of the glue bond breaking. We have developed the following guidelines to help reduce this risk.
We recommend using Lecol MS250+ adhesive when gluing wooden flooring to sub-floors.
It is essential when gluing to concrete that the concrete sub-floor is in a suitable condition.
Concrete must be vacuumed to remove any surface dust.
A suitable expansion gap should be left around the perimeter of the floor area and under doorframes. On a standard size room, i.e. up to 70 square metres, this is recommended as 15mm. For larger rooms, please call us for further advice.
A floating floor is when the wooden floorboards are fixed together and not fixed to the sub-floor.
We do not recommend solid hardwood flooring to be laid as a floating floor, due to the risk of movement.
Both Kahrs and Dennebos engineered flooring can be laid as a floating floor on any load-bearing sub-floor that meets our guidelines:
If your flooring is an 'unfinished' product it requires a finish (usually either an oil or a lacquer). Finishing an unfinished floor is a crucial part of its installation, and if you are unsure how to make your floor perfect, always consult a professional tradesman. As a guideline we have the following recommendations:
We recommend pre-oiled or pre-wax oiled floors are given an extra coat of oil once they have been laid. This tends to help lower the maintenance needed and restores any lustre lost during fitting:
Please ensure the initial guidelines given in the 'Room / Floor Preparation' section are followed.
