FIXINGS & LOCATIONS

Maglok™ Dragonboard® (MgSo4) does NOT require stainless fixings. Use corrosion protected cement board type fixings (grade3 galv).

Fixing into timber:   Recommended Simpson Strong-Tie 8G x50mm WSNTLG2SA collated screws or single screws.
Fixing into steel: Recommended Simpson Strong-Tie 10G x50mm CBSDGL158SA collated screws
Fixing  for fire rated floors:  Refer to technical information online.

Ensure all fixings are located:

• 12mm minimum from all butt edges.
• 50mm minimum from all corners and the shiplap joint.
• 200mm centres along all joists.

FRAMING GUIDELINES

Maglok™ Dragonboard® to be installed on construction is accordance with the below NZS standards.

  • Construction of timber framing must be in accordance with NZS 3604 – Timber-framed buildings
  • Construction of steel framing must be in accordance with NZ standards

It is always advised that the level of supporting framing be checked prior to installation for accuracy to ensure a level platform to install the flooring.

Ensure nogs are firmly connected to the joists and are dry as this can cause floors to creak under load.

SHEET SIZES

Color: Cream/white
1800 x 1200 x 20mm
Suitable for 600mm & 450mm joist spacings
2000x 1200 x 20mm
Suitable for 400mm joist spacings

STORAGE

Sheets should be kept under a cover if long periods between delivery and installation. Dry sheets are easier to lay and weigh less.
Like many materials, Maglok™ Dragonboard® will absorb moisture during construction. This will have no effect on the performance of the board and it will dry to its normal weight.

ON TIMBER JOISTS

  • Glue is required on the shiplap joint, lay a 10mm bead of glue on the shiplap prior to laying next board using Gorilla Grip 1 hour expanding polyurethane or Sika SuperGrip® 30 Minute expanding polyurethane.
  • It is also suggested that the sheets are glued to the joists and any nogs using a 10mm bead of Gorilla 940FC to assist in reducing possible movement that could result in a creak caused by tension built up as the timber dries.

ON STEEL JOISTS

  • When installing on steel joists, glue ship laps with Gorilla Grip 1 hour expanding polyurethane or Sika SuperGrip® 30 Minute expanding polyurethane, and also glue sheets to all joists using a 10mm bead of Gorilla 940FC

SHEET LAYOUT

  • Sheets are to be laid perpendicular to the joist with the ship lap edge spanning across the joist.
  • Sheets should be fitted to a staggered (brick pattern) layout.
  • Cut sheets can be butt jointed, but must be evenly supported by joist or nog.
  • Sheets can be fitted smooth or sanded side up.
  • The 1200mm ends of the sheets must be joined on the centre of the joist.
  • The 1800mm and 2000mm long sides of the sheets are ship lapped to avoid the use of nogs.
  • The ship lap is to be glued. Recommended glue is Gorilla Grip 1 Hour expanding polyurethane or Sika SuperGrip® 30 Minute expanding polyurethane.

CARPET

Use the long-nail version of smooth edge

VINYL PLANKS, CUSHION BACKED VINYL, TIMBER FLOORING

  • These can be installed requiring less or no surface preparation depending on the surface or the backing.
  • If the flooring is not a floating floor and requires gluing, see below:
  • Recommended glue system for Timber:
    Selleys Liquid Nails Direct Stick
  • Recommended glue for vinyl planks:
    Selleys Liquid Nails Direct Stick LF

CUTTING SHEETS

  • Use a Fibre Cement cutting wheel on a skill saw or plunge saw. Please refer to the Respiratory and Eye Protection statement below before you start.

WATERPROOFING AND TILE INSTALLATION

  • Recommended is the Cemix water proofing and adhesive system.
  • All tiled areas should be primed/sealed with Cemix Cemseal WB.
  • Waterproof with Tile Bond Latex/Rubberguard (and associated tapes)
  • Tiling over Rubberguard or for non-wet area:
    Refer to www.cemix.co.nz
  • When using white grout:
    Use Tile Bond Latex/ wallset white/ flexible grout
  • When using grey grout:
    Use Tile Bond Latex/Floor Tile Adhesive/Flexible Grout

VINYL SHEET INSTALLATION

CAUTION: If during construction the floor becomes saturated M60 cement can temporarily lose compressive/deflective performance. Once dry it will regain full strength. Good practice is to sweep surplus water off any flooring substrate.
Maglok™ Dragonboard® will not swell or delaminate like wood flooring if saturated for long periods.

RESPIRATORY AND EYE PROTECTION: Wearing of dust masks, eye protection, and ear protection is recommended when cutting or drilling Maglok™ Dragonboard®. These should be used in compliance with the BCA and ASTM standards. HAZARD: Maglok™ Dragonboard® contains fiberglass mesh.
