frequently asked questions


Q. What is the difference between Engineered and Solid wood flooring?

A. Engineered boards are made from several different layers of timber. The top layer of the board is a 4mm layer of oak glued to 11mm of crossover glued birch. The construction increases the stability of the planks and provides more versatile fitting options. Engineered boards are also suitable for use over underfloor heating.

Solid boards are cut from a single piece of timber and are of structural thickness. Traditionalists will be unanimous in their appreciation of solid flooring. We would not recommend installing solid timber boards over underfloor heating.

Q. I have been told that wood flooring has to acclimatise to the room in which it is to be installed. What does this mean?

A. The flooring should be placed in the room in which it is to be installed, unwrapped and lattice stacked, being separated by battens so as to allow the air to circulate. The room temperature should be between 15 to 25 degree centigrade and have a relative humidity of between 45 – 65%. Solid wood should be left for a minimum of 10 days, and engineered left for a minimum of 48 hours.

Q. Will any specialist equipment be required to fit the wood flooring?

A. Wood is sensitive to the moisture levels within the surrounding environment. One of the most important pieces of equipment will be a moisture meter to check the moisture levels are within the boundaries for laying the boards. We would strongly recommend the services of a suitably experienced fitter to carry out the work.

Q. What checks should be made before installing the flooring?

A. The floor substrate needs to be structurally sound, flat, clean and dry. The relative humidity of the floor substrate must be below 85%. Details can be found in the Fired Earth wood flooring installation guide.


Q. How are the engineered boards installed?

A. Engineered boards can be fully bonded to a suitably prepared substrate using Osmo MS Advanced Wood Adhesive or ‘floated’ over a suitable underlay. Please see the Fired Earth wood installation guide for further details.

Q. I am installing Fired Earth Engineered boards and plan to ‘float’ the boards on a suitable underlay on top of the existing floor surface. Will I need to use any adhesive with the engineered boards?

A. The use of a good quality, flooring grade PVA wood adhesive is recommended along the tongue and groove section of each board during installation.

Q. How are the solid boards, solid parquet and engineered parquet installed?

A.Solid boards, solid parquet and engineered parquet should be fully bonded to a suitably prepared substrate using Osmo MS Advanced Wood Adhesive. Please see the Fired Earth wood installation guide for further details.

Q. Do Fired Earth retail underlay for floating engineered floor installations?

A. There are a variety of different kinds of underlay for differing situations, for example: there are underlays for Underfloor heating, sound reduction and moisture control. Fired Earth are unable to stock underlay to cover all installation requirements. A suitably experienced installer would normally be able to advise on the most appropriate underlay and obtain this accordingly.

Q. Do Fired Earth retail wood finishing pieces for the installation?

A. Fired Earth stock a limited range of finishing pieces for the wood flooring range .These stocked finishing pieces are available in either washed plank or are unfinished. Unfinished pieces can be hand oiled on site using an appropriate coloured or natural Osmo hardwax oil. Please note: Hand oiling will always have a slightly different texture to the machine oiled boards.

Q. I am told that wood floors will expand and contract.

A. To accommodate the natural expansion and contraction of the wood a minimum 15mm expansion joint around the entire perimeter of the room is required as part of the installation. The expansion gap can be concealed with either a skirting board or hardwood beading. 


Q. Can I install the wood flooring over underfloor heating?

A. Only engineered planks are suitable to be installed over underfloor heating. Do not install solid timber planks or solid parquet over underfloor heating. Refer to the Fired Earth wood flooring guide for installation details.

Q. My prefinished Fired Earth Parquet flooring appears to have small gaps between some of the boards.

A. Having small gaps between each prefinished board is inevitable. Wood is a natural product and will therefore be sensitive to changes in surrounding moisture levels. Because of this characteristic, wood flooring will have a small amount of dimensional tolerance within it.

Q. How should I maintain my Fired Earth wood flooring?

A. For regular cleaning we would recommend the use of Osmo Wash and Care which removes most day-to-day stains from your floor. For more stubborn marks the correct Osmo Liquid Wax Cleaner is recommended.  Osmo Liquid Wax Cleaner will refresh the appearance of the floor and will top up the natural waxes used on the board’s surface. If necessary, small isolated areas of the floor can be carefully topped up with either the most appropriate Osmo coloured hard wax oil, or a natural hard wax oil. To help preserve the appearance of the floor, complete individual boards should be always be treated rather than making spot repairs with the hard wax oils.
