Arbosil LM is a one-part Neutral Cure Silicone Sealant that cures on exposure to moisture vapour to form an elastic silicone rubber.
For more information on Arbo, please visit their website here.
Arbosil LM is recommended for perimeter sealing of PVCu frames and sealing joints in brickwork, the MVP and Heel Bead methods of glazing insulating glass units, remedial glazing, and sealing joints in translucent roofing sheets. NB: It is not recommended for overpainting, glass wall assemblies and uses against natural stone.
The joint surfaces must be clean, dry and free from all contamination. The surfaces should be degreased using the appropriate Arbo Cleaner. Primers may be required on some substrates. It is recommended that Adshead Ratcliffe Technical Services Department should be consulted and advice obtained with regard to the choice of primer for specific purposes.
Where applicable, appropriate joint filler, e.g. closed-cell polyethylene foam, should be used to provide the correct joint depth. All joint preparation, priming, and sealant application should be carried out in accordance with BS 8000 Part 16, the British Standard for the sealing of joints in buildings using sealants.
Arbosil LM is supplied in polyethylene 310 and 380ml cartridges and can be applied into the joint using an Arbo Caulking Gun
