SURFACE PREPARATION

 

All surfaces must be structurally sound and all previous coatings, adhesives, efflorescence or laitance should be removed by chipping, abrasive blast cleaning, high pressure water washing, mechanical scrubbing or other suitable means. All surfaces must be cleaned free from dirt, grease oil or other surface contaminants. Holes, non-structural cracks and other surface deformities should be repaired.

 

APPLICATION

 

Porous concrete may require 3 coats of DuroWBE then join the two components, mixing thoroughly for a minimum of 5 minutes until a blended coating is obtained. Avoid trapping air during mixing as this may cause pin holing. Only mix as much as may be used within the pot life of the product. DuroWBE is a minimum two-coat system. Applying with a brush or roller, ensure to work the material into the substrate surface to fill voids and eliminate pin holing. Successive coats should be applied at right angles to the previous coat. It is recommended that the coating depth be tested at random points with a wet film gauge.

 

PRECAUTIONS

 

Refer to MSDS prior to use. DuroWBE cure rates will be dramatically slowed if the relative humidity is above 85%. Do not apply to steel or metal surfaces, as corrosion will occur. Do not add cementitious products to DuroWBE.  It is not a waterproof membrane on its own. A dedicated waterproofing membrane should be used. In enclosed areas, such as water tanks or reservoirs, basements, or cubicles, ventilation should be provided to enable adequate evaporation of the coating. Allow to cure for a minimum of 24hours at 25 C / 50% RH before applying waterproof membranes, adhesives, mortars, decorative coatings or other surface treatments.  It will tend to chalk when exposed to UV light. For external use apply a U.V. resistant top coat. Discard any material that has exceeded the pot life or working time of the product. Do not apply over any substrates that have been previously treated or coated with curing compounds, PVA concrete bonding agents or acrylic coatings. These areas must be mechanically cleaned by grinding or shot blasting to produce a contamination free surface.  It is rigid when cured and will not absorb movement cracks.

 

COLD SUBSTRATES AND COOL CLIMATIC CONDITIONS

 

Follow mixing instructions and allow an extra minute to ensure a homogeneous paste is obtained. Allow to stand for 5 minutes after mixing as this will accelerate the drying time. Never apply thin coats as the rapid moisture loss will arrest or slow the drying reaction and possibly cause an amine blush. Cure rates will be dramatically slowed if substrate surface or ambient temperature is below +10 C. If DuroWBE is applied in cooler climatic conditions, substrate temperatures can produce amine blush, resulting in an oily residue and or areas of uncured tacky discolorations. Ensure removal of the contamination prior to application of any further coating to ensure adhesion of the next coat. Before recoating,  it should be allowed to cure, then washed with clean, fresh water, Methylated Spirits or Xylene depending on the severity. Store it in a 20 C environment 24 hours prior to use. If possible warm substrate surface area by an air blower or use a blower after application. Always provide adequate ventilation during the drying cycle.

May cause sensitisation by skin contact. Irritating to eyes and skin. 
 

4. FIRST AID MEASURES

 

Eyes: Immediately flush with water for 15 minutes. Get medical attention if irritation develops or persists.

Skin: Take off all contaminated clothing. Wash contaminated area with soapy warm water. Get medical attention if irritation develops or persists. Wash contaminated clothing before reuse.

Inhalation: Remove to fresh air. Apply resuscitation if victim is not breathing. Give oxygen if breathing is difficult. Get medical attention.

Ingestion: Do NOT induce vomiting. Rinse mouth thoroughly. Give water to drink. Never give anything by mouth to an unconscious person. Call a doctor immediately. A decision to induce vomiting should be made by medical personnel.

Further Advice:

Contact a doctor or the Poisons Information Centre. Call Australia, 13 1126.

 

5. FIRE FIGHTING MEASURES

Auto-ignition Temperature: No data

Lower Explosive Limit: Not applicable

Upper Explosive Limit: Not applicable

Suitable Extinguishing Media:

Alcohol resistant foam is the preferred fire fighting medium but, if it is not available, normal foam can be used.

 

Protective Equipment for Fire Fighting:

Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.

Fire Fighting Procedures:

Use water spray to cool exposed containers. Stay up-wind and fight fire from a safe distance. Prevent spillage from entering drains or watercourses.

Decomposition Products:

Decomposes with fire to give off toxic and irritating fumes.

 

6. ACCIDENTAL RELEASE MEASURES

 

Small Spills: Caution : floor may be slippery. Wear suitable protective equipment and clothing to prevent eye and skin contact. Contain spill. Do not allow into drains or waterways. Take up with inert absorbent material (e.g. sand, dirt, or vermiculite). Fill into marked, sealable containers for disposal. Dispose of empty containers in accordance with federal, state and local laws.

Large Spills: Notify Emergency Services and advise nature of spill and material hazard. Isolate area.
