Frequently Asked Questions

The most effective adhesive for render beads is the same basecoat/render that you are using to coat the elevation. By properly embedding the beads, ensuring they meet depth requirements, and accommodating substrate irregularities, you’ll achieve a seamless façade finish.

While various adhesive options exist, it’s challenging to predict their compatibility and potential long-term issues with the render as it’s not certain what agents are in these products. For the best outcome, it’s advisable to stick with the same render for affixing the beads.

Alternatively, stainless steel fixings can be used, but it’s crucial they’re stainless steel to prevent rusting and render detachment from corners.

The choice of bead profile depends on the application. In thin coat systems like render carrier boards or external wall insulation with a maximum render depth of 6mm, a 6mm angle bead and stop bead are ideal. Meshed angle beads and protection beads enhance strength in these systems.

There are numerous profiles that complement these systems, and all offer their own unique attributes that assist with movement and contraction provisions as well as keeping an aesthetically pleasing look to the facades such as the slip joint and 6mm expansion profiles. ProBead Technical can provide more detailed information, just give them a call on 01647 24620.

For masonry applications, where a minimum 15mm render depth is required, 15mm bellcast render bead, stop beads, and angle bead profiles are used, aligning with SAS specifications and British standards EN 13194. ProBead offers various options, including wider-winged profiles.

For masonry applications, where a minimum render depth of 15mm is required in accordance with SAS specifications and British standards EN 13194, 15mm bell cast, stop and angle bead profiles would be used to reach depth requirements.

SAS offer 4mm, 6mm, 10mm, 15mm and 20mmm options including profiles with a wider wing.

Yes absolutely, the UPVC options are an excellent choice as they can be colour-matched to the render which is becoming more and more important for subcontractors, house builders and architects.

Their rust-free nature makes them suitable for severe locations, and they are easily cut and affixed to substrates, simplifying the application process.

ProBead provides high-quality render beads with an extensive colour range, backed by a 25-year warranty and BBA certification.

A stop bead is predominantly used for stopping the render. It’s used against soffits, window and door frames, and other surfaces where rendering isn’t desired. In some cases, it can also be paired back-to-back with a silicon joint to create an expansion detail.

For areas with moderate exposure, 15mm bead profiles are generally suitable for sand and cement rendering. However, in regions of severe or very severe conditions, increasing the sand and cement thickness to a minimum of 20mm may be necessary, requiring the use of 20mm profiles.

First, the beads would be cut to size to meet the margin requirement of the corner, using tin snips.

Choose the appropriate basecoat for the type of specification, ensuring compatibility. For thin coat systems, utilise ProRend Lite basecoat. For masonry, ProRend prep or alternatives like grip fill or stainless-steel fasteners can be used.

Precise levelling during installation using a spirit level is crucial, as the render follows the vertical alignment of the beads.

Remember, the art of plastering is in the preparation, get this right and the finish will follow, the bead installation plays an important role in this.

Yes, you would require them as they act as the datum for the render. The plastering contractor would use them to rule off from and they offer sharp edges, enhancing the façade’s visual appeal.

Additionally, beads protect vulnerable edges of the façade from environmental factors.
