R286-287 Blocker Primer
Blocker Primer Blocker primer is a two part system suitable for use over dry concrete, wet concrete, steel, aluminium, Lead, roofing felt, bitumen surfaces, such as roofing fell shingles, bitumen paint etc...
Always test the product fully in a small inconspicuous area of the surface to be
coated before proceeding. If the test results are satisfactory proceed to apply to
the whole area. Ensure 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. For further mixing ratios please contact the technical department
- Transfer mixed product to a roller tray and apply evenly to the surface using a medium-pile simulated sheepskin roller, brush or squeegee.
- Two coats must be applied. Once mixed the product must be used within 40 - 50 minutes @ 20c.
Always test a small hidden portion of the substrate before use, to ensure the
final result is satisfactory and to calculate consumption.
Primer may be required on certain surfaces such as: dry and wet concrete, steel, aluminium, lead, roofing felt and rigid bitumen based substrates. To establish if primer is required, perform an adhesion test with the waterproofing system before applying the product. See separate TDS for twin pack epoxy primer application (R235).
Ensure the surface is free from contaminants such as dirt, dust, oil, algae etc before proceeding to apply the product.
