Matacryl® BITU-PRIMER
Primer/Sealer for use under asphalt & bitumen based waterproofing systems
Description:
®
Matacryl Bitu-Primer is a low viscous, transparent,
2 component reactive resin based on methyl
methacrylate (MMA).
Properties:
• Excellent adhesion to concrete and metal
• Fast curing even at low temperatures down to
-5°C
• For critical weather conditions
• Resists heat from asphalt based waterproofing
• For use on fresh concrete
Areas of Application:
®
Matacryl Bitu-Primer is intended for use as a
primer/sealer
under
asphalt
or
bitumen
waterproofing. It has excellent bond to concrete and
metal substrates and also provides a good bond for
following waterproofing system.

Packaging:
20kg metal pails
Shelf Life:
12 months provided storage conditions are respected.
It is essential the product is stored in a cool and dry
place, protected from direct sunshine and in unbroken
originally closed packaging. The optimal storage
temperature is 15- 20°C.
Substrate Preparation:
All substrates must be dry, firm, solid and free of
dust, laitance, grease and oil.
Substrate temperature may range from 0°C to +40°C
with a moisture content of maximum 8% weight.
Application at dew point should be avoided.
Surface structure shall allow the correct application of
the primer.
• Surface tensile strength shall be min. 1.5 MPa.
• Mechanical preparation shall expose concrete
aggregate.
• Visible pinholes and craters shall be filled
separately using filled primer or suitable cement
mortar.
Mixing:
®
Prior to use Matacryl Bitu-Primer must be carefully
stirred to achieve a uniform distribution of the paraffin
®
and pigment contained in the product. Matacryl
Bitu-Primer is tho-roughly mixed together with the
®
Matacryl Catalyst (50% dibenzoyl peroxide), in
accordance with the below guidelines.
It should be noted that the amount of catalyst powder
to be added depends upon the substrate

Application:
• Substrate surface temperature may range from
0°C to 40°C.
• Do not apply when surface temperature is above
40°C and/or rapidly rising. Special care must be
observed if area is under exposure to direct
sunshine.
• Substrate temperature must be at least 3°C over
actual dew point.
• Avoid application if relative humidity in air is above
90 % and also in foggy conditions.
The complete primer/sealer system consists of two
coats. The first coat is applied by squeegee and
back- rolled at a rate of 0.5 kg/m2 and while still fresh
broad- cast with quartz size 0.7 – 1.2 mm at approx.
1 kg/m2.
A second layer is then applied by roller at a rate of
0.4- 0.6 kg/m2 and allowed to cure.
Health & Safety Precautions:
Suitable protective clothing, gloves and safety
goggles must be worn during mixing and application
®
of Matacryl Bitu-Primer.
When the product is applied in enclosed areas
without natural ventilation, forced ventilation must be
arranged. Avoid strong concentration of vapour as
well as direct contact with skin or eyes.
®
Matacryl Bitu-Primer is highly flammable; keep
away from heat and all sources of ignition and do not
smoke. The stirrer as well as all the other electric
appliances used on the application site must be
explosion-proof versions.
