How should I prepare my wood flooring before using Marldon MXA200 Adhesive?

Follow these simple steps to prepare your hardwood flooring before using Marldon MXA200 adhesive glue:

1. Ensure your subfloor is flat, clean, dry, sound, and free from contaminants that may hinder adhesion. This includes paint, varnish, polish, old residues and plaster spots. Existing wooden subfloors must have an effective membrane system or vented void beneath to prevent moisture/humidity ingress into the wood and affect the adhesive.
2. The subfloor should be tested in accordance with British Standards and a properly calibrated and insulated hygrometer should be used. A reading of 75% RH or less confirms that the subfloor is satisfactorily dry (65% with UFH). If this reading has not been attained, it is necessary to first apply Marldon Surface Membrane in order to suppress residual moisture.
3. Ensure the wood flooring is acclimatised in accordance with the manufacturer’s instructions. Always allow an expansion gap against all fixed objects to allow for seasonal natural movement of the wood floor when bonded.
4. Mechanically remove all surface treatments and laitance on concrete bases. Be sure to repair any deep indentations in the subfloor using a compatible levelling compound or repair mortar and grind off any ridges.
5. Lightly abrade calcium sulphate to remove any surface laitance. If needed, apply a suitable Marldon smoothing compound at a minimum thickness of 3mm. Not recommend for use over existing floor coverings.
6. Wood floorboards should be overlaid with suitable sheet product such as plywood with a minimum thickness of 6mm. Ensure the wood floor manufacturer recommends the wood flooring for use with the particular substrate.
7. Ensure substrate is suitable for the adhesive before application. Porous substrates should be primed with MXS120 Universal Primer. Always prime before applying a suitable Marldon smoothing compound to calcium sulphate screed.

How can I install hardwood flooring using Marldon’s MXA200 Adhesive?

1. Choose a suitable triangular notch trowel size (i.e., 4mm or B6) for the sub-floor and wood flooring to ensure a minimum of 80% contact between the adhesive bed and the underside of the flooring. Subfloor should meet British Standard tolerances. A deeper notched trowel may be required depending on the subfloor and for larger solid boards etc. This will adversely affect the coverage rate of the adhesive.
2. Spread the adhesive in a sweeping motion and place the wood into the adhesive while it is still wet. Press the wood firmly into the adhesive to ensure good overall contact. Lift occasional boards to ensure sufficient adhesive transfer has occurred. Where necessary use heavy objects to hold the wood firmly in place during curing time.
3. The bonded timber flooring will be suitable to take foot traffic 6 to 8 hours after application. It should be left for 48 hours before sanding or finishing takes place.
4. Use in well-ventilated conditions and ensure all recommended protective equipment is worn during handling & use of this product.
