APPLICATION
Apply the product by means of a manual-, battery- or pneumatic- caulking gun. Apply Lead Sheet Sealant evenly without air inclusions into the joint. Smoothen the joint with a spatula with the help of finishing solution. Avoid that soapy solution comes between the joint edges and sealant (to prevent adhesion loss).
Application method: With a manual, pneumatic or accu caulking gun.
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.
LIMITATIONS
– Do not use on natural stones like marble, granite,…(staining). Use Soudal Silirub MA or Silirub+ S8800 for this application.
– Direct contact with the secondary sealing of insulating glass units (insulation) and the PVB-film of safety glass must be avoided.
– Because of the diversity we recommend to do adhesion tests on aluminum lackers, textured coating and PVC before application.
– In an acid environment or in a dark room, a sealant can slightly turn yellow. Under the influence of sunlight it can turn back to its initial colour.
– When finished with a finishing solution or soapy solution, make sure that the surfaces are not touched by this solution. This will cause the sealant not to adhere to that surface. Therefore we recommend to only dip the finishing tool in this solution.
– Do not use in applications where continuous water immersion is possible.
– Do not use on polycarbonate. Use Silirub PC instead.
– When using different reactive joint sealants, the first joint sealant must be completely hardened before the next one is applied.
– 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 discolouration and loss of adhesion.
