Arbomeric MP20 is recommended for many forms of construction, including structural joints in heavy cladding, structural movement joints in floors and floor joints in heavily-trafficked areas.

APPLICATION INSTRUCTIONS 

Joint Preparation 

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. 

Joint Backing 

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.
