Arbomeric MP20 is a one-part high modulus modified polymer sealant that cures on exposure to moisture vapour to form a tough but elastic rubber.
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. NB Not recommended for joints in lightweight cladding and swimming pools. It is over-paintable once fully cured; pre-use tests are advised to demonstrate compatibility with individual paints.

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.
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.
Arbomeric MP20 is supplied in polyethylene 380ml cartridges and 600ml foils.
