External Render Beads can be fiixed by either dot or dabs with an adhesive mortar/render or a non-corrosive wall plug and screw. Alternatively, they can be fixed using a non-solvent based adhesive sealant similar to CT1 or similar hybrid polymer adhesive sealants. You must not use interior grade solvent based or silicone adhesive sealants. For further guidance please contact your ISLE CORK Company representative a Render Bead Company authorised distributor.
