PHS Ottello adhesive sealant is a water-based contact adhesive, designed to create a permanent connection between airtight layers. It is best suited to bonding and sealing airtight vapor control layers (AVCL) membranes to substrates, to create and airtight building envelope. It has as a broad range of applications, one of its most important applications is the joining of membrane to blockwork such as a ceiling AVCL, lapping down to join to the masonry wall in order to create a continuous airtight and vapour control layer. The sealant excels in this application due to its ability to create a strong bond with rough surfaces.

Application

Application Areas:

Interior adhesive between airtight layers.
All construction types.
Ceilings, walls, floors and loft spaces.

Application Guide:

The substrates must be clean and dry.
Impurities such as dust, grease, oil, tar, bitumen and release agents must be removed.
Sandy and rough surfaces may need to be pre-treated with a primer.
Apply the sealant with an 8mm thick bead on a fixed surface.
Increase the sealant thickness where the surface is uneven.
For wet applications, the airtightness layer must be gently pressed down with a relief loop so that a 3-4 mm thick an adhesive seal layer is maintained.
In dry applications, pressure is required to ensure a strong bond to the airtightness layer.
The airtightness layer must be stress free and fastened.
