X’traseal MS-609 is a high-initial-grab MS polymer adhesive for fixing compatible mirrors, skirting boards, decorative wall panels, thresholds and building components. It offers strong early hold with an elastic cured bond, making it useful for vertical assembly where conventional wet adhesives tend to slip.
Choose MS-609 for component bonding and mounting, rather than for trowelling timber flooring. The supplier's technical data supports compatible mirror bonding with appropriate testing, along with metals, HPL panels, finished timber, porcelain, polystyrene, polycarbonate and other tested surfaces. For parquetry and wood floors choose MS-608 instead.
Apply to clean, sound, dry surfaces and press components together, maintaining approximately 2–3 mm adhesive thickness. Its fast initial grip often reduces temporary bracing, but heavy, overhead or safety-critical items may still require support or mechanical fixing. Allow curing before exposing the bond to substantial loads.
Do not use on polyethylene, polypropylene, PTFE, plasticiser-containing materials, bitumen, underwater joints or for structural glazing. Test coatings and mirrors on original materials before relying on adhesion.
Compare MS polymer grab adhesives for compatible panel and trim fixing. For joints where accommodating movement is the main task, see MS polymer sealants.
How quickly does MS-609 grab?
It provides immediate wet grab, but heavy or highly stressed parts still need support until cure.
How thick should the bond line be?
Keep at least 2mm adhesive thickness so the cured polymer can remain elastic.
Can MS-609 be painted?
It is compatible with water-based paint systems after cure. Alkyd paints may dry more slowly.
Can it be used for structural glazing?
No. Use a dedicated structural glazing silicone.
