- Multipurpose sealing and bonding in the building sector, even onto humid and damp Surfaces.
- Connection low movement wall joints (horizontal and vertical), e.g. joints between
- window or door frames and brickwork, for stairs, balconies, etc.
- Suitable of installing (sealing and bonding) of windowsils, skirting boards, covering boards, etc.
- Elastic bonding and sealing in many different industrial applications.
- Joints in ventilation & air-conditioning ductwork.
- Bonding in vibrating constructions (vehicle body, containers, metal-to-metal).
- Direction for Use
Surface preparation and sealant application:
Cleaning and joint preparation
Substrates (joint flanks) must be clean, and free of dust, grease and other contaminant which may affect the adhesion. Non-porous surfaces (such as aluminum, glass, etc.) should be cleaned with a suitable solvent. Porous substrates (such as concrete, brickwork, etc.) must be mechanically cleaned from loose particles. Mask off the joint edges.
Primer:
OLIVE MP-20HM adheres to most common construction materials without primer. However, a preliminary adhesion test is recommended on every surface. Sometimes, it may be necessary to treat the joint surfaces with a primer to obtain better adhesion performances. Please, contact us for technical assistance.
Inserting backing material
Use the closed cell polyethylene backer foam OLIVE CORDON PE as a back-up material to limit the sealant joint depth and avoid the sealant to adhere to the joint base. Choose the right backing strip diameter (at least 25% wider than the joint width).
Sealant application
After substrate preparation, apply the sealant with a professional caulking gun, evenly and without bubbles. Observe the eventually used primer's open time before filling the joint.
Tooling and finishing
The joint should be tooled and smoothed before skin formation. Press the sealant and smooth it ensuring good contact with the surfaces to seal. Use a spatula or neutral soapy water as a tooling agent. Remove masking tape. Uncured product may be easily removed with solvents such isopropyl alcohol or "white spirit". Cured sealant must be removed mechanically.Remarks
Do not use OLIVE MP-20HM on bituminous substrates or on building materials which might bleed oils, plasticizers or solvents (e.g. natural rubber, chloroprene, EPDM)
There is no adhesion to PE, PP, PTFE (Teflon®). Due to the wide variety of possible substrates, we recommend a preliminary compatibility test.
Paintability: Due to the large number of paints and varnishes available we strongly suggest a compatibility test before application.
Not intended for structural glazing.- Joint Design
Expansion joints should be correctly dimensioned taking account of dimensional changes in the substrates due to thermal filuctuations. Joint's dimensions should match with the sealant movement capability, with a maximum permitted value of 25%
Use closed cell polyethylene backer foam (Olive Backer Rod) as a back-up material to
limit the sealant joint depth and avoid three-sided adhesion.
The following general rules/recommendations should be followedGeneral statement: The ideal joint has a 2:1 width: depth ratio
Minimum joint dimensions 5-6mm width x 5-6 mm depth.
Up to 12 mm wide: Width = depth From 12mm to 24mm wide Depth = ½ width Wider than 24mm Depth = 12-15mm
Expansion joints should not be wider than 50mm
