Buildon Gypsum Blocks

BUILDON Gypsum Blocks are for all Internal Wall requirements which will benefit not just in better and faster construction but will also reduce the cost as compared to Conventional Wall or Brick.

The blocks which measure 500mm x 666mm x 80mm have excellent acoustic and fire performance.

The solid gypsum blocks are formed with a smooth face that does not need plastering and is ready to accept either a paper, tiled or painted finish.

Each block is moulded with an interlocking tongue and groove joint in the horizontal and vertical edges. The joints are bonded with gypsum adhesive (BUILDON Block bond or Buildon Gypsum Plaster One Coat).

BUILDON Gypsum Blocks are environment friendly, creative and effective, made from best quality gypsum ideal for all partition walls.

INSTALLATION & APPLICATION

    1. The block should be transported with care and pallets should not be stacked to avoid damage.
    2. Blocks should be protected from Water and moisture both during transportation and whilst stored on site.
    3. The walls should be set out using either a chalk line or timber runner. The floor should be clean and free from dust, flat and level prior to commencing laying of blocks.
    4. The first course of block is laid on a bed of Buildon Block Bond. Care must be taken in laying the first course to ensure line and level.
    5. In laying the first course of blocks ensure the vertical joints are between the blocks and bonded with Buildon Block Bond lightly tapping with a rubber hammer to ensure the tongue and groove interlock and excess adhesive is squeezed out.
    6. The second course of block commences with a half block laid on a bed of Buildon Block Bond, tap lightly into place to ensure the horizontal tongue and grooves interlock and excess plaster is squeezed out of the joint.
    7. The line and level of the wall should be continuous. The blocks should be continued to be laid such that the vertical joints are staggered between courses.
    8. The top course should be completed by cutting the blocks and where necessary incorporating a soft joint between the top of the block and the soffit of the structure to avoid load transfer.
    9. Excess jointing plaster should be removed from the joints after approximately 30 Minutes.
    10. Intersecting walls should be either bonded in or tied with proprietary metal tie.
    11. Opening and chasings for services should be formed using the correct tools such as a wall chasing machine. Chiselling or other impact tools should not be used.The chases should be filled with Buildon Block Bond and trowelled to achieve a smooth flat finish.
    12. External corners should be finished with an expanded metal.
    13. Finishing is subjective and depending upon the quality of finish required. The joints and any other defects in the form of grooves etc can be made good by filling and smoothing with Buildon Block Bond or Buildon Gypsum plaster. If a higher quality finish is required a  slurry coat of plaster maybe applied to the whole of the wall.
