Durapond

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 Durapond.
•       Cementitious and brick surfaces:  Durapond can be applied directly to cement, stone, brick and fibre-cement provided they are completely dry and clean. Cement should be allowed to hard cure for at least 28 days before applying Durapond. Where the substrate is not completely dry or where rising damp is expected, prime with Duram Duraprime epoxy primer as per instructions. Where Duraprime has been used, apply Durapond when the Duraprime is touch dry (approx. 2 hours), but for best adhesion do not allow the Duraprime to hard cure (24 hours). Duraprime is not colourfast and therefore should not be used in conjunction with clear Durapond.
•       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 Durapond 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 Durapond directly.

 

APPLICATION

•       Do not apply Durapond if the surface is damp or if rain is expected.
•       Do not apply Durapond directly over bituminous sealers without first applying a coat of Duraprime to avoid solvent attack.
•       Stir Durapond well and do not dilute.
•       Apply by brush or roller to a clean, firm, dry, prepared surface.
•       Apply first coat of Durapond thinly to prepared surface at a rate of 0,5 litre/m². Do not apply too thickly as it is preferable to build up film thickness by applying three coats or more. Allow to dry for 6 to 24 hrs depending on conditions. Once dried, apply second coat at a rate of 0,5 litre/m² to the first coat. Once dried, apply third coat at a rate of 0,5 litre/m² to the 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.
•       Once cured (96 hours), wash down surface with water and a light detergent. Rinse well at least twice with fresh water before filling with drinking water or introducing fish. A water test is recommended for sensitive fish.
•       Partly used cans may be stored for short periods and should be tightly sealed and stored upside down.
•       Durapond can be overcoated with polyurethane coatings.
 
CLEANING

Durapond can be removed from tools and skin only in its uncured state, using Duram Xylene.

 

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 Durapond from curing, while water will cause it to foam and cure in the can.
•       Durapond is unsuitable for use in swimming pools.
•       Not resistant to HTH or hypochlorite containing compounds.
•       Colours are not colourfast.

 

SAFETY PRECAUTIONS

•       Flammable in wet state.
•       Keep out of reach of children.
•       Wear rubber gloves and protective clothing. Avoid contact with skin and eyes. Durapond 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.
