Maintenance & Care Guide for Hardwood & Laminate Floors.
All hardwood and laminate floors regardless of what type of finish, must be maintained properly to keep the beauty long lasting. We have listed the basic recommendations to care for your new floor. It is always recommended that you follow the flooring manufactures maintained guide which comes with the floor.
Sweep or vacuum the floor (with an appropriate broom or vacuum attachment) regularly to keep it clean and free of dirt, oil, dust, grit, and other abrasive and foreign materials.
Place area rugs or doormats at entryways to help prevent abrasive or staining materials from being tracked onto the floor surface from outdoors. Avoid rubber backed or similarly dense matting materials that may trap moisture between the mat and the floor. Choose mats that enable airflow instead and do not discolour the floor.
Place protective mats a high use work areas such as sinks and workstations.
Protect the floor from any exposure to liquids, water or other forms of moisture.
Use a damp, not wet, and clean cloth to wipe up spilled food, drink or other liquid immediately
Never wet mop the floor when cleaning.
Avoid walking on the floor with wet feet or footwear.
Install felt pads or soft bottomed castors on the feet of all furniture and accessories that will be placed directly onto the floor surface.
Avoid letting sharp or pointed objects come into contact with the floor. Do not walk on the floor with high heeled shoes or other types of footwear which may damage the finish or cause indentations to the surface.
Do not drag, push or roll appliances, furniture or any other objects across the floor.
Never use any household or furniture dust remover, polish or similar products.
Never use any steel wool, scouring pad or any other abrasive cleaners.
Only use cleaning products recommended by the flooring manufacture
