- Application Method
- Cure Method
- Applications
- All usual building joints with high movement.
- Connection joints between window frames, doorframes and walls.
- Expansion joints between many different construction materials.
- Joints with large movement.
- Sealing of shrinking joints in concrete floors
- Sealing of floor joints
- Direction for use
Substrates
- Substrates: all usual building substrates, brick, concrete, metals, ...
- Nature: clean, dry, free of dust and grease.
- Surface preparation: Soudaflex PU35 has good adhesion to most substrates. In critical situations or to obtain optimum adhesion, use Primer 100 on porous surfaces.
- Always use Primer 100 on natural stone, no primer on non-porous substrates.
- No adhesion on glass, PE, PP and PTFE (Teflon). Soudal recommends a preliminary adhesion test on every surface.
Joint dimensions
- Min. width for joints: 3/16”
- Max. width for joints: 1 3/16”
- Min. depth for joints: 3/16”
- Recommendation sealing jobs: joint width = 2 x joint depth.
Applications
- Application method: With manual- or pneumatic caulking
- Cleaning: Clean with White Spirit or Soudal Surface
- Cleaner immediately after use (before curing).
- Finishing: With a soapy solution or Soudal Finishing
- Solution before skinning.
- Repair: With the same material
- Remarks
- When painted with oxidative drying paints disturbances in the drying of the paint may occur (we recommend doing a compatibility test before application).
- Soudaflex PU35 has a good UV resistance but can discolor under extreme conditions or after very long UV exposure. It is recommended to do a compatibility test prior to application.
- Contact with bitumen, tar or other plasticizer releasing materials such as EPDM, neoprene, butyl, etc. is to be avoided since it can give rise to discoloration and loss of adhesion.
- Do not apply or cure in the presence of uncured silicone sealants, alcohol or other solvent cleaners. When using different reactive joint sealants, the first joint sealant must be completely hardened before the next one is applied.
