Ultimately if you employ a professional floor installer, it is his/her responsibility to ensure the floor is installed correctly, but Mulveys strongly recommend the following best practices.
Before installation commences, it is best practice to open a box first and if the homeowner is happy with the finished product, open at least 25% of the floor and “rack” it out over the floor. The reason for this is to spread out any knots and colour variation throughout the floor. When 25% is fitted, open another 25% and repeat.
NB: if after opening the first box and you are not happy with the floor for whatever reason, DO NOT FIT or open any more boxes. Contact your place of purchase for advice.
It is best practice to leave the flooring in the box up until installation.
Every floor, regardless of the fitting method must be installed against a straight line. It is best practice to measure out 3-4 boards plus expansion from the starting wall and using a chalk line, set a straight line. Then, securely fix a strong straight batten along the line. You then install the floor against this. When you are finished the main part of the room, remove the batten and back fix the last 3 or 4 boards. If you are installing random length solid flooring, it is best practice to nail or glue down (using Flex-Floor 920) to the subfloor.
If is very important to leave an expansion gap around the full perimeter of any wood or laminate floor. This includes at doors between rooms. It is necessary and best practice to put a threshold at all doorways and a moulding or similar over the expansion gap around fire places.
Use only the recommended cleaners to maintain floors. It is best practice to use only a small quantity of water.
Do not fit any floor over a concrete subfloor with a higher than 3% moisture content. If moisture block is used, up to 6% is allowed. If in any doubt, contact Mulveys of Dundrum for advice.
When purchasing a wooden floor, it is best practice to purchase an extra 5% of material, over and above the measured area. There will always be an amount of natural wastage, due to cutting, natural defects or personal choice on a small number of boards.
