DESCRIPTION
ReadySeal Blocker Primer is a two-component primer that creates a barrier preventing bitumen oils from bleeding through into ReadySeal Liquid Applied Waterproofing Membrane, preventing discolouration and adhesion loss when overlaying new or old bitumen membranes.
ReadySeal Blocker Primer is also suitable for use as a primer for new or old PVC Single Ply Membranes, dry and partially cured concrete, steel, aluminium and lead.
Designed as a two-coat application when used as a bitumen blocker. All other applications may be suitable for single coat application depending on condition.
Uses:
• To prevent bleed the bleed through of the oils in Reinforced bitumen Membranes/Bitumen coatings.
• To create a key when overlaying PVC Single Ply Membranes
• To create a key to steel, aluminum and lead.
• To eliminate the risk of pin holing in ReadySeal when applying over damp concrete.
Certificates:
BBA Certification No. 20/5797.
APPLICATION
Always test the primer and top coat fully before proceeding. If the test results are satisfactory proceed to apply to the whole area.
Ensure the surface is clean, dry and free from any contaminants including dust, dirt, oil, grease, algae and efflorescence. The product is moisture tolerant when used on concrete.
Add part ‘B’ to Part ‘A’ using a jiffy mixer blade attached to a slow running electric drill. DO NOT mix by hand as this can lead to areas of uncured material. Once mixed the product MUST be used within 40 – 50 minutes @ 20ºC.
Transfer mixed product to a roller tray and apply evenly to the surface using a medium-pile simulated sheepskin roller. brush or squeegee. Apply at a rate of approximately 4m² / kg (at 200 microns thickness coating weight coverage will vary according to the texture, porosity and evenness of the surface).
When used as a Bitumen Blocker/Primer
Allow the first coat to cure for a period of 12 hours before applying a second coat. Allow the second coat to cure for a period of 12 hours before applying the ReadySeal Liquid Applied Waterproofing Membrane. Two coats must be applied to ensure the performance stated is met.
When used in all other stated applications
Allow the first coat to cure for a period of 12 hours before applying the ReadySeal.
ReadySeal Blocker Primer MUST be overlaid no later than 24 hours after application and should not be applied below 5ºC.
Cleaning of Equipment:
Remove as much product as possible before cleaning. Clean tools and equipment immediately after use with suitable solvents such as Acetone, Thinners etc.
