Durabak
Duram Durabak is a versatile single pack polyurethane non-slip coating
for bakkies, trucks, trailers and other areas where a long lasting, tough
protective liner is needed. It has an attractive, tough, textured finish with
excellent capacity to repel water and withstand abrasion and chemical
splashes. With high adhesion to metal, concrete, wood, fibre-glass, PVC
and rubber, it will not chip, flake or peel, even with impact. Available in
an economical spray or brush-on format, it is easy to apply and dries
quickly.

PRODU CT USES
Duram Durabak can be used to:
•
Protect the load beds and tail lifts of trucks and bakkies from rust and petrol and diesel splashes.
•
Create non-slip areas on walkways, stair edges, ramps and around machinery.
•
Provide non-slip areas for boats, showers and change room floors.
•
To create non-slip areas for wheelchair access, emergency exits and fire escapes.

Tough and weather resistant.
Easy to apply - no skilled labour required.
Will not taint water or food once cured.
Bonds to most surfaces except unprimed metal and olefin polymers, eg. PE and PP.
Non-slip.
Can be overcoated.
Resists many solvents and has good chemical resistance to organic and inorganic acids.
Abrasion resistant.

Total coverage: About 1m per litre applied in two coats i.e. 2m per litre per coat.

Substrates differ significantly, and so all new applications should be tested first.
Ensure all substrates are thoroughly clean, sound, dry and free from any contaminants such as dirt, rust, salt, algae and grease.
•
Cement: Old and new cement or concrete surfaces must be acid-etched, rinsed well and dried. Prime with Duram Duraprime epoxy primer if damp
or oil contaminated.
•
Steel: steel surfaces to be free of mill scale, rust, grease and well abraded. Prime with Duram NS5 Metcote.
•
Galvanized steel: Wash with Duram NS2 Galvanized Iron Cleaner until a water break-free surface is attained. Rinse well with water. Allow to dry.
Apply Duram NS6 Galvanized Iron Primer the same day as the surface was prepared to avoid re-contamination and flash rust.

Aluminium: Abrade to fresh metal and prime with Duram NS5 Metcote within 30 minutes. For applications where pooling of water is expected, a
specific waterproof primer for aluminium is required.
•
Fibre-glass: Abrade well and apply Duram NS5 Metcote. Underwater applications require a waterproof primer (Duram NS5 Metcote should not be
used in these instances).
•
Timber: Abrade before applying Duram Durabak.
•
Gloss Paints and Varnish: Abrade to remove all gloss.
•
Rubber (nitrile or chloropene): Clean well using detergent or cleaning solvent. Allow to dry. Test adhesion first.
All primers to be selected, applied and overcoated to manufacturers specifications.
Duram Durabak exhibits good adhesion to acrylic, epoxy and polyurethane primers..

Ensure substrates have been prepared.
Ensure tests for adhesion have been completed.
Ensure areas not to be coated have been masked off.
Stir well before use.
Spray On: Screw spray gun onto can, and attach airline providing a minimum pressure of 5 bar. Duram Durabak should be applied in thin coats to
prevent “mudcracking” during drying. Depending on the application, two or more coats can be applied, allowing time for all solvents to evaporate
between coats. Intercoat time is approximately 2 hours (when touch dry) depending on ambient conditions.
Brush On: Duram Durabak should be “laid” onto the surface with a brush (do not brush backwards and forwards as with an enamel paint). Two
coats will result in a final dry film thickness of 0,75mm to 1mm. Second or subsequent coats should be applied at right angles to the previous coat.
Intercoat times approximately 2 hrs depending on ambient conditions.
Roller: If applied with a stipple roller, application is quicker and the final texture rougher with greater non-slip characteristics. Follow same
instructions as per Brush On. Intercoat times approximately 2 hrs depending on ambient conditions.
Curing time: Duram Durabak cures with atmospheric moisture. Without accelerator the coating will be touch dry in about 2 to 4 hrs, allowing light
traffic after 12 hrs, and achieves full strength and chemical resistance in 4 to 7 days, but normally coating can be put to use after 24 hours.
Accelerated cure: In areas of low atmospheric moisture or when shorter curing times are required, an accelerator can be added. This is available
from manufacturer or supplier.
Overcoating and repair: Duram Durabak can easily be repaired or overcoated. The old surface should be well cleaned and then abraded by wire
brush or sandpaper, damaged surfaces must be cut out to provide an area without loose edges. Follow application instructions. If Durabak is left for
more than 24 hrs after coating, it should be abraded before recoating to aid intercoat adhesion.
CLEAN IN G
Uncured Duram Durabak:
Cured Duram Durabak:
can be cleaned in its uncured state using Duram Xylene.
can be removed with Duram Durastripp paint stripper or by mechanical means.
IMP ORTA NT
•
•
•
•
•
Do not clean surfaces with Lacquer thinners.
Do not mix with water, turps, thinners or any solvent containing water or alcohol. Alcohol will prevent Duram Durabak from curing, while water will
cause it to foam and cure in the can.
Do not apply to bare metal without an appropriate primer.
Once opened use Durabak within 2 hours or 1 hour if accelerator is used.
Protect from moisture and do not expose to temperatures above 50 ºC.
SAFETY PR ECAU TI ONS
•
•
•
•
•
Duram Durabak is highly flammable in its wet state, solvents released during spraying, observe all fire precautions.
Remove any overspray immediately. Durabak is very difficult to remove once cured.
Ensure good ventilation to prevent build up of flammable solvents.
Wear goggles, rubber gloves.
Accident Measures:
•
Spillage/leakage: Do not empty into drains; keep away from sources of ignition. Ensure ventilation in working area. Take up with
absorbent material. Fill into sealable containers.
•
Extinguishing media: extinguishing powder, CO2 or halones.
•
Eye contact: rinse with water.
•
Skin contact: wash with soap and water.
•
Should Durabak be swallowed seek medical advice.
