Joint Design
The joint width must be designed to suit the joint movement required and the movement capability of the sealant. For joints ≥ 10 mm and ≤ 20 mm wide, a joint depth of 10 mm is recommended.
For larger joints please contact our Technical Service Department.

SUBSTRATE PREPARATION
The substrate must be sound, clean, dry and free of all contaminants such as dirts, oil, grease, old sealants and poorly bonded paint coatings which could affect adhesion of the sealant. The substrate must be of sufficient strength to resist the stresses induced by the sealant during movement. All dust, loose and friable material must be completely removed from all surfaces using suitable equipment before application of any activators, primers or sealant.
Sikasil®-119 MP adheres without primers and/ or activators. For optimum adhesion, joint durability and critical, high performance applications such as joints on multi storey buildings, highly stressed joints, extreme weather exposure or water immersion/ exposure. The following priming and/ or pre-treatment procedures must be followed:
Non-porous substrates:
Aluminium, anodised aluminium, stainless steel, galvanised steel, powder coated metals or glazed tiles. Slightly roughen surface with a fine abrasive pad. Clean and pre-treat using Sika® Aktivator-205, applied with a clean cloth. Before sealing, allow a waiting time of > 15 minutes (< 6 hours). Other metals, such as brass and titanium-zinc, also have to be cleaned and pre-treated using Sika® Aktivator-205, applied with a clean cloth. After the necessary a waiting time, use a brush to apply Sika® Primer-3 N and allow a further waiting time of > 30 minutes (< 8 hours) before sealing the joints.
PVC has to be cleaned and pre-treated using Sika® Primer-215 applied with a brush. Before sealing, allow a waiting time of > 30 minutes (< 8 hours).
Glass must be cleaned with Isopropyl alcohol before application.
Porous substrates:
Porous substrates must be primed using Sika® Primer-3 N applied by brush. Before sealing, allow a waiting time of > 30 minutes (<8 hours). Adhesion tests on project specific substrates must be performed and procedures agreed with all parties before full project application.
For more detailed advice and instructions please contact Sika Technical Services.
Note: Primers and activators are adhesion promoters and not an alternative to improve poor preparation/ cleaning of the joint surface. Primers also improve the long term performance of the sealed joint.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Remover-208 immediately after use. Hardened material can only be removed mechanically. For cleaning skin, use Sika® Cleaning Wipes-100.
