Removal techniques such as wire brushing, grinding, grit blasting or other suitable mechanical tools can be used. 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). 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).

All joints must be correctly designed and dimensioned in accordance with the relevant standards and codes of practice before their construction. The basis for calculation of the necessary joint widths are the type of structure, dimensions, technical values of the adjacent building materials, joint sealing material and the specific exposure of the building and the joints. All dust, loose and friable material must be completely removed from all surfaces before application of any activators, primers or sealant. The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Sikaflex® Construction+ adheres without primers and/or activators. 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.CE Marking and Declaration of Performance to EN 15651-4 - Sealants for non-structural use in joints in buildings - Sealants for pedestrian walkways. Classification: PW EXT-INT CC 25 HM The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles.

Standard specification for elastic joint sealants, ASTM C920-11 Class 35, ASTM, Report, No 0314920-SIKA PVC has to be cleaned and pre-treated using Sika® Primer-215 applied with a brush. Before sealing, allow a drying time of > 30 minutes (< 8 hours). Where joints in substrate are saw cut: after sawing, all slurry material must be flushed away and joint surfaces allowed to dry. The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Sikaflex® PRO adheres without primers and/or activators. 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.

Sika Pro Select Sealants

Winches, windlasses are subject to high mechanical stresses, fans, hatches and hatch covers to low stresses. To make sure your fittings are sealed strongly we recommend the following: Aluminium, anodised aluminium, stainless steel, PVC, 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.
