Sikaflex Pro Sealant

Description

Sikaflex Pro Sealant

310ml Cartridges and 600ml Sausages

 
Sikaflex PRO Sealant is designed for movement and connection joints on porous
substrates as well as indoor and outdoor general sealing applications. Sikaflex PRO
bonds strongly to porous and dense substrates like brick, cement, ceramics, metals,
and timber without requiring a primer in most cases. It cures into a tough, elastic
seal that offers high weathering and aging resistance.
Sikaflex PRO comes as a ready-to-use formulation that is easy to gun and apply on
vertical and horizontal surfaces without sagging. It can accommodate expansion and
contraction rates of 25% to 30% in building materials without cracking.

SUBSTRATE PREPARATION

• The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles.
• Sikaflex PRO Sealant adheres without primers and/or activators.
• However, for optimum adhesion and critical, high performance applications, such as on multi-story buildings, highly stressed joints, extreme weather exposure or water immersion, the following priming and/or pre-treatment procedures shall be followed:
  

  Non-porous substrates

• Aluminium, anodised aluminium, stainless steel, galvanised steel, powder coated metals or glazed tiles have to be cleaned and pre-treated using Sika® Aktivator-205, wiped on with a clean towel.
• Before sealing, allow a flash-off time of > 15 minutes (< 6 hours).
• Other metals, such as copper, brass and titanium-zinc, also have to be cleaned and pre-treated using Sika® Aktivator-205,wiped on with a clean towel.
• After the necessary flash-off time, use a brush to apply Sika® Primer-3 N and allow a further flash-off 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 flash-off time of > 30 minutes (< 8 hours).

Porous substrates

• Concrete, aerated concrete and cement based renders, mortars and bricks shall be primed using Sika® Primer-3 N applied with a brush.
• Before sealing, allow a flash-off time of > 30 minutes (< 8 hours).
