How to Use

Fixing Recommendations

Preparation

Masonry walls may have large irregularities in the surface and these should be dubbed out and made even prior to fixing any type of render beads. This allows the render to be applied evenly and speeds up fixing the beads and applying the render.

Adhesive Mortar or mudding on

Renderplas PVC plaster beads and plaster trims should be mudded on with a line of adhesive mortar or dabs of render. This helps the bead or trim to be plumbed completely straight and provides additional rigidity when applying spray render, acrylic render, or trowelling on other traditional render coatings. Where through-coloured render coatings are used, the PVC plaster bead will not deflect when trowelling off.

Mechanical Fixings — Nail Clouts or Staples

Care should be taken not to deform an external render bead when using mechanical fixings, whether they are Renderplas PVC render beads or traditional metal beads. A supporting baton is only necessary to maintain straightness whilst fixing a PVC render bead horizontally whilse the render or mortar goes off. This should not be necessary when using special adhesive mortar. Beads can be fixed with stainless steel nails directly onto the substrate as the flexible wing on the render bead compensates for irregularities in the surface. As all our PVC plastering products can be used inside and outside, they can be quickly fixed using stainless steel staples when working with suitable substrates like cement board or plasterboard.

Cutting to Length

PVC render beads and plaster beads are cut using tin snips or alternatively for tricky mitres or the largest movement joints, a fine-toothed hacksaw. PVC pipe weld adhesive can be used to form a strong bond on butt joints.

Storage

Store horizontally away from direct hot sun. Whilst Renderplas PVC beads are packaged in the highest quality fibreboard tubes and cardboard boxes, care should be taken to ensure the boxes are kept straight.
