Sika Sikalastic Metal Primer N
Sika Liquid Plastics Metal Primer N is a 2 pack anti-corrosive primer for application to exposed metal substrates prior to the application of Sika Liquid Plastics Roofing and Balcony Waterproofing Systems.
Best Uses
Sika Liquid Plastics Metal Primer N is a 2 part epoxy anti-corrosive primer consisting of a grey base (Part A) and an activator (Part B), used as part of the Decothane Base Coat and Decothane Balcony waterproofing system a single component, cold-applied, moisture-triggered polyurethane membrane. It cures to form a seamless, durable and weather resistant waterproofing solution for exposed roof areas.
- Fast curing, overcoat possible in 6 hours
- Easy application by brush or roller
- Enhances adhesion to broad range of metalic substrates
- Protects against migration of volatile bitumen substrates (inconjuction with fully reinforced systems)
- Can be overcoated with a wide range range of Sika Liquid Applied Waterproofing Membranes
Sikalastic® Metal Primer N is a primer for metal substrate for use with:
- Decothane Ultra® Roofing Systems
- Sikalastic® roofing systems
- Sikalastic® balcony systems
Application
SUBSTRATE PREPARATION
All surfaces to be coated should be thoroughly cleaned by conventional means. Steel is ideally prepared by shot blasting to Sa 2 1⁄2 or SSPC 10 (nearly white metal). Where blasting is not permitted then clean metal preparation by power tools is acceptable. Non-ferrous metals are prepared by removing deposits of dust and oxidation and abrade to white metal. Wire brushing can be used on soft metals, i.e. copper. Ensure that surfaces are free from visible dampness and that all dust, loose and friable material is completely removed from all surfaces before application of the product, preferably by brush and/or vacuum. If in doubt apply a test area first.
APPLICATION
Prepare Sikalastic® Metal Primer N by stirring component A until uniform, add component B and mix by electric drill until a homogeneous colour is achieved and the product is free of streaks. Sikalastic® Metal Primer N can be applied by shortpiled roller or brush. Allow primer to dry sufficiently (see table waiting time/overcoating) before overcoating.
