Application Instruction

 SURFACE PREPARATION AND PRIMING

 Substrates differ significantly, and so all new applications should be tested first. All surfaces must be sound, dry and free of oils or greases. Loose and flaking paint or varnish should be removed. As Duradek is a moisture-curing product, all substrates must be dry before application of Duradek. 
 
  • Fibreglass: No primer required. Lightly scuff with a scouring pad to remove gloss if necessary. 
·         Timber: Ensure that any waxy timber treatment products are removed and that the wood is dry before application.
·         Old gloss paints and varnish: Abrade to remove all gloss. Solvent wipe.
·         Steel: To be free of mill scale, rust, grease and well abraded. Anti-corrosion primer recommended.
·         Galvanised steel: Scour with alkaline detergent or galvanised pre-cleaner to a water break free surface. Anti-corrosion primer is recommended.
·         Aluminium: Abrade to fresh metal and prime with a 2K aluminium etch primer within 30 minutes.
·         Cement: Old and new cement or concrete surfaces must be cleaned, rinsed well, dried and primed with a water-based epoxy primer e.g. Duraprime.
 
Duradek exhibits good adhesion to acrylic, epoxy and polyurethane primers.
  
APPLICATION INSTRUCTIONS
 
Ensure substrates have been prepared; tests for adhesion completed and areas not to be coated have been masked off. Stir well before use. Duradek is best applied with a brush, however a short-hair roller can be used to speed up the process. Lay the paint out with the roller and use the brush to touch it up.
 
The product should be applied in two or more thin coats at right angles to one another, ensuring maximum coverage. Do not allow the product to form pools, as the non-slip particles will not stand proud.
·         Curing time: Duradek cures with atmospheric moisture. Depending on temperature and humidity the coating will be touch dry in about 60 – 90 minutes per coat. Light traffic will not damage the coating after 6 hours and full serviceability is achieved after 12 hours. Final strengthand chemical resistance is achieved after 3 to 4 days.
·         Overcoating and repair: Duradek can easily be repaired or overcoated. The old surface should be well cleaned and then solvent wiped just prior to application. 
 
SOLVENT/CLEANING
 
If thinning is necessary, use up to 10% of xylene. Do not use any solvent containing water or alcohols as this will prevent drying.
Spills and brushes can be easily cleaned with solvent after the drying time but before final cure.
Note: Do not use equipment previously cleaned in solvents other than xylene with this product, unless completely dry such that no water or alcohols come into contact with this product.
 
PRECAUTIONS
 
·         Do not clean porous surfaces with solvents other than xylene as water and alcohols may be retained and prevent drying of Duradek.
·         Do not apply to bare aluminium without an appropriate 2K primer.
·         Duradek is highly flammable in its wet state due to its solvent content. Observe all fire precautions.
·         Remove any overspray immediately; Duradek is very difficult to remove once cured.
·         Once opened use Duradek within 4 hours or a skin may form.
·         If a skin forms, remove skin carefully to avoid lumps in the product.
·         Ensure good ventilation to prevent build up of flammable solvents.
·         Protect from moisture and do not expose unopened cans to temperatures above 50ºC.
·         Wear goggles and rubber gloves. Duradek bonds to the skin and can only be removed with a pommel stone.
·         If applying Duradek daily, a cartridge-type half face mask with replaceable cartridges for organic fumes should be worn.
  
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 halogens.
·         Eye contact: rinse with water. If pain persists see a physician.
·         Skin contact: wash with soap and water. Discolouration may persist for a few days.
·         Should Duradek be swallowed seek medical advice.
