On of our recent installations in St Albans, off Bernards Heath, involved installing a parquet floor over water-based underfloor heating (UFH). At the request of the main contractor (for whom we had not worked previously) we specified a 280mm Oak multi-layered parquet block. On top of the UFH it is imperative that an engineered parquet block is used, as this has much greater structural stability and is not so affected by the heat coming through the floor.
After taking moisture readings it was still deemed necessary to facilitate the use of a liquid, surface damp-proof membrane (DPM). This was so as to prevent any residual moisture from getting into the blocks. A DPM is applied by roller and has the beneficial effect of improving the adhesion of any glue used for the blocks. Being based in St Albans allowed us to make good progress on the floor and the fitting aspect was completed in less than three days.
After the wood was allowed to acclimatise, we proceeded to fit the first three rows before allowing the glue to go off. The bulk of the floor was subsequently filled out, prior to cutting the border back.
Once the two-strip border had been fitted, the floor was then allowed a few days grace to fully settle in prior to sanding.
As the engineering of the blocks was to a good standard, only a light sand was required and only minor gap filling required.
The floor finish was the Osmo floor oil. One coat of colour oil (amber) to darken the floor gave it a golden brown glow. This was followed by a single coat of Osmo Polyx Oil in a matt finish. In all the floor has been a great success and is a major feature of the house.
