Installation
The
better the installation, sanding and finishing of your new or refurbished
hardwood floor, the better it will look and the longer it will last. Our
service is divided in to their individual sections of installation, sanding
and finishing.
Following are some rules that we observed when laying Timber Flooring:
Acclimatisation
Flooring timber is usually kiln-dried to a moisture content of 10-15%. It is
important to allow the timber to adjust to the prevailing air moisture
levels before fixing, as this will help avoid problems caused by swelling or
shrinkage.
Adequate Sub-Floor Ventilation
Sub-floor ventilation is probably the most significant factor contributing
to either the successful installation or failure of a timber floor.
Excessive humidity in the under-floor area may be caused by either a lack of
sufficient cross-ventilation or from damp soil conditions arising from
inadequate drainage. These conditions lead to swelling ( bugling and
cupping) of the flooring and possibly its eventual decay, plus an unhealthy
mustiness within the house. There is little benefit in providing excellent
cross-ventilation if the sub-floor area remains wet due to poor drainage or
seepage. Drainage must be improved if there is any indication of persistent
dampness.
Concrete Floors & Moisture Content
When laying timber floors directly onto or over a concrete slab, it is
vitally important that the concrete is dry to a point where no appreciable
moisture will be taken up by the flooring.
Avoid Fixing in Extreme Weather Conditions
Periods of excess rain or dry heat before laying will cause the timber to
either gain or lose moisture. Allow a period of normal weather before fixing
to prevent subsequent swelling or shrinkage problems.
Protect from Wet Trades and Exposure to Weather
Where possible, avoid fixing the flooring until work by the wet trades has
been completed. If this is not possible, an alternative may be to lay the
flooring face down on the joists and cover with polythene sheeting until the
wet trades have finished.
Sanding and Finishing
After sanding is complete, the floor is vacuumed or swept clean and
carefully inspected for scratches and undulations, as these will be
highlighted by the finishing coats.
