The key to a successful installation is your sub floor preparation. Taking the time to get this right will minimise the possibility of movement which often leads to creaking or moisture ingress which can cause a multitude of problems.
To conform to industry standard BS-8201-2011 the sub floor should be sound, level, smooth, dry and free from undulation. There should be checks undertaken to ensure there is no trace of damp rot, fungal or insect infestation and contaminating residue.
Surface irregularities must not exceed 3mm over a 2m area and hot pipes should be well insulated to prevent hot spots as this may cause excessive shrinkage.
Sub floors may appear dry at the surface but moisture can still be present within the substrate. Using a professional moisture reader such as a Protimeter MMS will give accurate readings. Please ensure the following is adhered to:
- 70% Relative Humidity (RH) for cement based concrete
- 11% Wood Moisture Equivalent (WME) for wooden sub floors or joists.
Liquid or foil Damp Proof Membranes (DPM) are recommended for extra piece of mind when laying over concrete or water based sub floors.
Always use the correct levelling compounds suitable for Real Wood Flooring, If unsure check with the manufacturer.
