(a) Surface Preparation
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 ORGANIX technical support. Any existing coating must be checked for good adhesion. The loosen materials should be removed well. Clean by wire brush and use pressured air to blow out all the dust.

(b) Tools required - Tools or equipments to be used for the application

  • Roller (Short nap roller)
  • Brush (Good quality synthetic bristle brush)
  • Spray (Airless Sprayer, 1gpm, 3,000 psi, .027 or.031 tip)

(c) Reinforcing with FLEXIK.
Overlaps, corroded edges, penetrations of pipes or ducting should be reinforced by FLEXIK reinforcement or any approved compatible material (Contact ORGANIX for selecting the proper reinforcement product). If the reinforcement is by mat or fabric,apply a light coat of Liquid DRYTEX HB500, center the reinforcement fabric on the overlap and roll it out taking care not to create wrinkles press fabric down with squeegee. All fasteners should be sealed or capped with DRYTEX HB500 or SEALFLEX sealant with reinforcement material.

(d) Coating Application
All substrate-preparation materials must be allowed to dry prior to application of the DRYTEX HB500 coating. Immediately prior to application of the coating, all dust, dirt and other contaminants should be blown off the roof surfaces using compressed air. As it is a ready to use product, just mix the single pack itself thoroughly before use. Cover the entire roof substrate as follows. Apply the basecoat at a rate of minimum 0.6 kg/sq.m. After allowing the basecoat to dry, apply the topcoat at a rate of minimum 0.6 kg / sq.m 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.
