Duram 195

Duram 195 is a high-performance polyurethane waterproofing solution which is highly flexible and strong, allowing it to withstand high water pressure, temperature changes and structural movement. When it dries, Duram 195 forms a seamless waterproof membrane that is effective in fresh or salt water. It also protects surfaces from corrosion and degradation.

Colours: Black

PRODUCT USES

You can use Duram 195 to waterproof:

• Dams, reservoirs and water features that don’t contain drinking water.
• Flat roofs and balconies.
• Roof screws and gutters.
• Under tiles and screeds.
• Below grade retaining walls and basements.
• Bonds to concrete, masonry, brick, fibre-glass, wood, metal and some plastics (plastics lightly abraded with medium grit sandpaper).

Important Note: Duram 195 is not suitable for fishponds, swimming pools, or any containers carrying potable or drinking water.

ADVANTAGES

• Premium waterproofing compound.
• Withstands permanent immersion in water.
• Withstands abnormal water pressure, structural movement and temperature fluctuation.
• Minimal maintenance required.
• Exceptional strength, flexibility (> 300%) and adhesion.
• Excellent weather and chemical resistance.
• Forms a seamless membrane.
• Adheres well to most surfaces.
• Suitable for vertical and horizontal surfaces.
• Quick and easy to apply.
• Does not harden or go brittle over time.
• A single component solution, so there is no measuring or mixing – simply brush it on.
• Self flashing – bonds against penetrations, outlets, supports, columns and walls.
• Resists water creep unlike torch-on membranes.
• Can be easily touched up.

COVERAGE

• 1.2 m² per litre per coat. Applied in a 2 coat application. Coverage will vary depending on the porosity and profile of the surface.
• The wet film thickness should be 750 microns per coat, resulting in a final dry film thickness of 1.3 – 1.4mm.

SURFACE PREPARATION

• Surfaces to be waterproofed must be clean, sound, dry (less than 10% moisture content where applicable) and free of all surface contamination such as form release agents, curing compounds, oil, grease and dust. Damage to the substrate must first be repaired. Remove any sharp protrusions that may damage the Duram 195 coating.
• Cementitious and brick surfaces: Prime with a coat of Duram Duraprime epoxy primer. Apply Duram 195 when the Duraprime is touch dry (approx. 4 hours), but for best adhesion do not allow the Duraprime to hard cure (24 hours). Concrete surfaces with airholes should be adequately bagged.
• Aluminium: Freshly roughened surfaces must be primed with a two component aluminium primer as per manufacturer’s instructions.
• Fibre-glass: Unweathered fibre-glass and gelcoats must be sanded to remove all gloss and wiped with a solvent. Then apply Duram 195 direct.
• New galvanized iron: Clean surface with Duram NS2 Galvanized Iron Cleaner according to instructions. Rinse thoroughly with water and allow to dry. Apply Duram NS6 Galvanized Iron Primer and allow to dry.
• New steel: Remove any surface rust or mill scale by sanding or wire brushing. Rinse with Duram Xylene or lacquer thinners to remove sanding dust and any oils or grease. Allow to dry. Apply Duram 195 directly.
• Expansion joints and cracks: A high quality joint sealant should be applied to expansion joints and cracks exceeding 15mm.

APPLICATION

• Do not apply Duram 195 if the surface is damp or if rain is expected.
• Do not apply Duram 195 directly over bituminous sealers without first applying a coat of Duraprime to avoid solvent attack. Duraprime is not necessary for acrylic-bound bituminous sealers.
• Stir Duram 195 vigorously for a few minutes which will thin the compound.
• Do not dilute.
• Apply by brush or roller to a clean, firm, dry, prepared surface.
• Apply first coat of Duram 195 to prepared surface.
• Allow to dry for 12 to 24 hrs depending on conditions. Once dried, apply second coat. Further coats may be applied for additional protection.
• On structural corners, upstands, cracks, full bores and imperfections, Duram Duramesh reinforcing membrane should be embedded into the first
  wet coat.
• Partly used cans may be stored for short periods and should be tightly sealed and stored upside down.
• Topcoating:
  • Duram 195 does not need to be overcoated, but can be covered, if required, with a Bitumen Aluminium paint, tiles, slate, roof sheets or stone chips.

CLEANING

Use Duram Xylene or other solvent to remove uncured Duram 195.

IMPORTANT

• Thin only if necessary and use only Duram Xylene.
• Do not mix with water, turps, thinners or any solvent containing water or alcohol. Alcohol will prevent Duram 195 from curing, while water will cause it
  to foam and cure in the can.
• Duram 195 is not suitable for fishponds, swimming pools, or any containers carrying potable or drinking water.
• Do not apply Duram 195 on bitumen surfaces.
• Do not apply if rain is imminent.

SAFETY PRECAUTIONS

• Flammable in wet state.
• Keep out of reach of children.
• Wear rubber gloves and protective clothing. Avoid contact with skin and eyes. Duram 195 bonds to skin, clothing etc and is very difficult to remove once cured. If skin contact occurs, remove contaminated clothing and wash skin thoroughly with soap and water.
• Use in a well ventilated area to prevent build up of solvent vapours. Avoid breathing solvent vapours. May cause coughing and lung irritation, headache, dizziness, nausea.
• If swallowed, contact a doctor or poison control centre. Do not induce vomiting. Drink water.
