Installing Amtico on Wood Sub Floors

  • The application of Amtico tiles or Spacia tiles over new suspended timber or metal joisted floors should be made onto specially manufactured flooring grade plywood, laid and fixed in accordance with the manufacturers’ recommendations.
  • The spacing of floor joists or supporting battens should be in accordance with the board manufacturers’ recommendations in relation to board thickness and anticipated floor loadings.
  • Chipboard can be sensitive to movement caused by service conditions and as such it is not recommended that Amtico is installed directly onto chipboard; it should be overlaid with plywood.
  • Plywood should normally be 6 mm exterior grade to WBP (weather and boil proof) or American Plywood Association (APA) standard. The thickness selected should be determined by the quality of the surface regularity of the existing boarding, the traffic intensity and applied floor loadings. In particularly heavily trafficked commercial areas, a thicker grade of plywood may be required
  • Panels should be acclimatised to the job site long enough to stabilise to atmospheric conditions since dimensional changes occur with fluctuations in ambient humidity. This is accomplished by standing individual panels on edge for several days in the location where they will be installed.
  • Always check with the panel manufacturer for recommendations as to installation requirements and acceptable conditions prior to specifying or installing any panel.
  • Under-layment panels should be protected against physical damage or water prior to application.
  • Prior to overlaying, loose floor boards should be firmly nailed down. If necessary the boards should be planed and levelled with a suitable levelling compound prior to covering with plywood. The base may require priming before applying the levelling compound. Nail heads and screws should be finished flush and filled to give a smooth finish. Where spot stapling is used the contractor must ensure that the underlying floor boards are firmly fixed.
  • The plywood should be laid in sheet sizes not exceeding 2400 x 1200 mm, using twisted shank or ring shank nails, or serrated staples. Fixing should start at the centre of each sheet, nailing at 100 mm centres along the perimeters with the fixing line 12 mm from the edge, and at 150 mm intervals at intermediate centres. All nail heads should be finished flush with the surface.
  • Joint lines should be staggered, and every effort made to prevent coincidence of joints in the sheets and the timber base. We would recommend the use of a suitable repair/finishing compound to smooth the joints of plywood.
