METHOD OF USE:
– Substrate preparation:
The substrate must be clean, dry, even, dense and free from oil, grease, dust and other contaminants. A clean surface will ensure maximum adhesion between the substrate and the coating. Concrete ﬂoors must have a minimum compressive strength of
25N/mm2 and a maximum concrete relative humidity of 80% (max a maximum concrete of 4%), relative humidity can be measured using a hygrometer. Concrete relative humidity should be less than
80% for concrete 28 days old or more.
– Surface preparation:
Unsound layers and contaminated concrete surfaces must be prepared using mechanical surface removing equipment. Acid etching can be used only in well ventilated areas. Areas deeply contaminated by oil or grease, such areas should be treated by hot compressed air.
POLYWED EPOXY 770 exhibits excellent wear, abrasion and chemical resistance and is suitable for use in a wide variety of industrial and commercial applications. It can be used to provide a surface coating with a high gloss hygienic ﬁnish or a slip resistant coating system.
POLYWED EPOXY 770 provides impermeable protection against common oils, greases, lubricants, aviation fuels and hydraulic oils such as Skydrol. As in all corrosive situations, a full analysis of operating and exposure conditions is required, followed by reference to chemical resistance data to ensure product suitability.
Add the entire contents of the reactor container into the base container and mix the two components for 2 minutes using a slow speed drill ﬁtted with a special mixing head until all striations have disappeared and a uniform color is obtained.
Use brush or lambs wool roller, or airless spry machine to apply the mixed POLYWED EPOXY 770 onto the prepared surfaces. Apply 2 coats of POLYWED EPOXY 770 at 3m2/kg per each coat, second coat should be applied at a right angle to the ﬁrst coat. The second coat may be applied as soon as the ﬁrst coat has initially dried. Drying time depend on the substrate and the ambient conditions. If the over coating time is exceeded the ﬁrst coat must be abraded with sand paper prior to the application of the second coat.
Adequate ventilation must be provided to ensure that necessary drying and curing of the material is achieved.
– Antislip Application:
The base coat should be applied at a minimum ﬁlm thickness of 250 micron and then fully blinded with the chosen antislip aggregate. Once the base coat has reached initial cure, all excess aggregate should be removed before a further application of POLYWED EPOXY 770 top coat.
The top coat should be applied at minimum ﬁlm thickness of 400 micron to 750 micron depending on antislip aggregate size used.
POLYWED EPOXY 770 should not be applied at temperature below 100C or where ambient relative humidity exceeds 85%. POLYWED EPOXY 770 should not be applied onto surfaces know to suffer from rising damp. In case of spry application, airless spry machines should be used.
POLYWED EPOXY 770 is available in 5kg and 15kg cans.
– Smooth ﬁnish:
6 liter pack of POLYWED EPOXY 770 covers 20m² @ a dft of 200 microns (two coats required).
– Slip-resistant ﬁnish:
6 liter pack of POLYWED EPOXY 770 covers 16m² at a dft of 250 microns (2 coats required).
Store in a dry area out of direct sunlight between 5˚C and 35˚C.
POLYWED EPOXY 770 has a shelf life of 12 months if stored in proper conditions and un-opened packs.
– Health and Safety:
POLYWED EPOXY 770 should not come in contact with skin and eyes. In case of accidental splashes to the eyes, rinse thoroughly with clean water and seek medical advice. Suitable protective gloves and goggles should be worn.
Do not use solvent to clean POLYWED EPOXY 770 from skin. For further information consult the material safety data sheet available for this product.
POLYWED EPOXY 770 and POLYWED-SOLVENT are ﬂammable. Ensure adequate ventilation. Do not use near a naked ﬂame and do not smoke during use.
