INSTALLATION (Surface Preparation)
Make sure the surfaces to be coated must be clean, dry and free of any oil, grease or dirt. Patch and repair cracks, blisters and other problem areas using suitable materials recommended by Isoflex technical support. Before over coating to old substrates should be washed with high pressure jet water pump. Any existing coating must be checked for good adhesion. The loose existing waterproof systems should be removed well.
Application Tools or equipments to be used for the application
1. Roller (Short nap roller) 2. Brush (Good quality synthetic bristle brush) 3. Spray (Airless Sprayer, 1gpm, 3,000 psi, .027 or .031 tip)
Reinforcing of seams and overlaps
Overlaps, corroded edges, penetrations of pipes or ducting should b reinforced by reinforcing mat or fabric or Maxi wrap (for suggestions contact isoflex Tech Team).
All roof-preparation materials must be allowed to dry prior to application of the coating. Immediately prior to application of the coating, all dust, dirt and other contaminants should be blown off the roof surfaces using compressed air. Cover the entire roof substrate as follows.
1. Apply the basecoat at a minimum thickness of 600 Micron
2. After allowing the basecoat to dry, apply the topcoat at a minimum rate of 2sq.m per 1.2 liter using a cross hatch technique. Apply the elastomeric coating by brush, roller or airless spray, using a multi pass spray technique to ensure even coating application to all sides of the substrate. Make a conscious effort to apply coating into crimped or pre-sealed vertical (side-lap) seams that have not been detailed.
3. The coating minimum dry-film thickness required at any location is 1200 micron. This is generally considered the minimum coating thickness for a 15 years product warranty. For extended coverage periods, additional coats and heavier film builds will be required.
