- Fields of Applications
- Sealing of expansion joints between porous and non-porous substrates including concrete, masonry, brick, aluminum (lacquered, anodized, painted,..), PVC, glass, ceramics and most plastics.

- Sealing of transformed and treated glass. Curtain wall sealing.
- Perimeter and connection joints for aluminum, wood and PVC carpentry.
- Direction for Use
Surface preparation and sealant application:
Cleaning and joint preparation:
Substrates joint flanks) must be clean, dry, 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 and thoroughly dried with a clean cloth.
Porous substrates (such as concrete, brickwork, etc.) must be mechanically cleaned from loose particles. Mask off the joint edges.
Primer
OLIVE C-40 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.
Product Application Olive PRIMER 10 Porous surfaces. (e.g. concrete, cement, marble, natural and artificial stone, etc.)Olive PRIMER 20: Non-porous surfaces. (e.g. aluminum, iron, stainless steel, zinc, copper, brass, painted surfaces and most plastics)Olive PRIMER 80DS: All surfaces. Substrates exceptionally difficult to adhere on.
Inserting backing material
Use the closed cell polyethylene backer foam OLIVE CORDON CELULAR as a back-up material to limit the sealant joint depth and avoid the sealant to adhere to the joit base. Choose the right backing strip diameter (at least 25% wider than the joint width).
Silicone 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.Remarks
Do not use OLIVE C-40 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.
OLIVE C-40 cannot be overpainted.
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 followed
General 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
