PART 2-EXECUTION

2.01 CAUTIONSup.gif

Urethane coatings typically contain organic solvents and as such can be toxic and flammable. Work only in fully ventilated areas. Do not smoke when using these products or use near sparks, heat, or any open flames. Read and follow the Tough Stuff Material Safety Data Sheets (MSDS). All waste materials including empty pails must be removed from the site by the applicator and taken to a landfill authorized to receive such materials.

2.02 MIXINGup.gif

Urethanes and primers will require proper mixing before application as follows:

    PRODUCT MIX TIME
    AC5600, PR3200, PR3300, PR3600 None
    UR2550, UR2650, UR2750 Four minutes (two part)
    PR3500 One minute (two part - five minute digest after mixing)
    PR3400, PR3450, AC5000, AC5900, UR1600, UR1700, UR1800 One minute


2.03 SUBSTRATE PREPARATIONup.gif

A. CLEANING:

Remove dirt, and foreign material detrimental to adhesion or application of roofing. Use CL404 cleaner diluted 20:1 with water. On heavy dirt or grease, apply full strength. Broom scrub the soap solution on the membrane to loosen oxidation and dirt and rinse with a minimum 2500 psi water blaster. If there are algae growing on the surface, the cleaning must include bleach in the washing of the substrate.

B. FASTENERS:

Examine existing system for loose fasteners and gapped seams. Pay particular attention to the horizontal seams. These seams have to be tight before detailing. Replace stripped fasteners with an oversized version of the same fastener, i.e. aluminum, galvanized, or stainless must remain as designed by the manufacturer.

2.04 PRIMINGup.gif

MEMBRANE PRIMER COVERAGE
RUST PR3400 .33 gal./sq.
ASPHALT AC5600 .5 gal./sq.
TRANSITE PR3500 .5 gal./sq.
COATINGS PR3600 .2 gal./sq.

2.05 DETAILING JOINTSup.gif

Transite roof configurations will dictate the type of seam detail required for complete waterproofing. Certain roof matrix conditions will not require that all seams are detailed. Consult Coatings International Roofing Systems for detail variances.

A. VERTICAL SEAMS:

Vertical joints will be finished in a fashion relative to the existing condition.

  1. Vertical Seam System A: Hand or pump applied mastic.
    1. Brush or pump mastic into joints.
  2. Vertical Seam System B: Reinforced with polyester.
    1. Apply UR1700 or AC5000 on joint at 1.5 gallons/square.
    2. Set 4” polyester in wet material. Apply additional material at 1.5 gallons/square and fully saturate the polyester.
    3. If standing alone, apply an additional layer of material at 1.5 gallons/square.

B. FASTENERS:

    Fasteners are detailed as required to make the system watertight.

    1. Dab each fastener with UR1700 mastic.

C. HORIZONTAL LAP JOINTS:

    1. Apply base coat of UR1700 urethane at a rate of 1.5 gallons/square directly on the seam to be detailed.
    2. Integrate desired width of polyester liner into wet base coat and brush into place with no wrinkles. Apply a top coat of UR1700 at a rate of 1.5 gallons/square over liner.
    3. Allow to skin and apply a brush coat of light mastic over the joint to feather the edges.

2.06 CURB SADDLESup.gif

Machine curbs with standing water behind can be filled using UR2550 urethane filled with D210 ceramic additive. Additive is 50/50 by volume with equal displacement (50% filling adds 50% volume).

  1. Pour material in depression until level with roofing ribs.
  2. Allow to set and reinforce transition at edges with UR1700 and polyester liner.

2.07 APPLICATION OF FINISH COAT(S)up.gif

    Spray or brush finish coats in multiple passes to achieve required mils.

2.08 INSTALLATION OF WALKWAYSup.gif

Apply additional layer(s) of the finish at 1.5-2.0 gallons/square with optional aggregate. Aggregate can be added to the mixture or broadcast into the wet material.
