“Timber is a living product”
Timber has the ability to gain or lose small amounts of moisture, depending on its surroundings. It expands or contracts to suit the conditions. You must keep this in mind when storing or laying timber.
1. Site Conditions
Site history: Check flooring for moisture content
Air Moisture: Depending on humidity at the site will be one of the determining factors of the moisture of your flooring. Equilibrium Moisture Content (EMC) can on average vary between 10% – 20%, each percentage relates to movement of ten millimetres over four metres. This variation can lead to cupping and gaps in your flooring.
Drainage: Adequate drainage must be in place to direct surface water away from the building
Ventilation: All under-floor spaces must be dry with cross ventilation from outside vents and no dead air spaces. There must be openings in all internal sub-floor walls that correspond with external vents to maximise airflow.
If there is evidence of moisture in the ground under the sub-floor, plastic membrane should be laid over the ground.
If the floor is to be installed over a concrete slab, the slab must be fully cured (i.e. below 5% moisture). Slab must be moisture tested and there are moisture membrane products available.
Direct Sunlight: Northerly or westerly sunlight directly on the floor may need to be filtered.
All wet trades must be finished prior to delivering the flooring
2. Delivery & Storage
Ironwood prefers to store the timber at their warehouse until flooring is required.
Once on-site, the flooring must be stored indoors where it is fully protected from moisture and sunlight.
Remove the plastic wrapping from the pack once it is under cover to improve air circulation and prevent sweating.
3. Installation, Sanding and Finishing
Flooring can be installed on joists, although optimum results will be achieved if the flooring is fixed to a plywood platform.
Ironwood has its own floor layers, sanders and polishers. Our layers are reliable and experienced in laying wide board floors and have an exemplary track record for servicing our clients.
Our service provides you with a reliable assessment of your sub-floor moisture situation, remedies to fix potential moisture issues and gives you a timetable to get your job complete.
Recycled Timber Flooring is a unique product which is manufactured from timber joists from old houses, warehouses and bridges. As such recycled timber has varying degrees of feature which may be bolt holes, nail holes, rust feature and surface weathering.
Often builders, floor layers and carpenters who are not used to recycled flooring think when the timber arrives that it is faulty. When the product is laid, sanded and polished they can appreciate the unique and prestigious look of the completed product.
For this reason we would always like to have our floor layers and sander/polishers work on the product.
