Adhere without fear! We talk you through our handy hints and tips for beading at speed and how to prevent staining or ruining your render.
Metal or plastic beads?
The benefits of using plastic beads far outweigh using metal beads. Not only are the majority more cost effective but they will save you pain and potentially more money in the future if you need to right any problems that may occur.
Metal beads (including powder coated) will discolour and rust which will cause unsightly spots & damage render. They can also expand which could lead to render falling off.
Plastic beads are easier and safer to use, they can be cut with a pair of normal tin snips, help you section your work area and produce nice crisp lines in the render.
If you're using coloured render you can also purchase coloured plastic beads from some manufactures to match the colour of your render.
Common problems with fixing beads
There are typically a range of different methods used for fixing beads but some of these can result in undesirable outcomes.
Adhesives which are not specifically manufactured for use on render beads can lead to staining in render.
Gypsum-based adhesives sometimes are used to adhere beads, however this reacts with the moisture in render and causes unsightly delamination.
Using nails can result in rust and corrosion leaving rust spots and staining on the render.
Fixing the beads
Place dabs of bead adhesive directly to the substrate at a minimum of 300mm centres apart for vertical planes.
A dab constitutes of a bed of material to width of the bead wing (40mm), it should be approximately 100mm in length and to a minimum thickness of 15mm.
Press the bead firmly into the freshly applied dabs with a trowel; ensuring the bead wing is fully embedded. Trowel the excess material away as you fix the bead (please note the bead adhesive needs to be set back from the nose of the profile to ensure render coverage of at least 10 to 12mm).
