Subfloor bearers need to be strong enough to hold the rest of the floor up. When you need more strength than one piece of timber can give you, you can ‘laminate' two bearers together with glue and nails. Apply a generous amount of construction glue on the surface of one bearer. Place a second bearer on top of the first and slide it around to spread the glue. Then line the two pieces up so their edges are flush and double nail them along the whole length.
Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.
