BOARD-STOCK INSULATION
STEP 1 – Cleaning
All roof surfaces must be clean, dry, structurally sound,
stable, well secured and free of excessive ponding
water.
Inspect condition of flashing details, penetrations, roof
mounted equipment, curbs, walls, parapets, drains and
roof edges to ensure that they are sound.
Ensure that the roof deck has positive slope to drain
and that moisture content of the existing substrate,
insulation and deck does not exceed 15%.

STEP 2 – Preparation
Remove all loose gravel, dirt and debris to smooth the
surface prior to application of the board-stock insulation.
Care should be taken to preserve the integrity of the
existing roof substrate whenever possible. Any unsound
areas in the roof deck, insulation or flashings must be
repaired or replaced.
All blisters, delaminations, wrinkles and loose areas
must either be cut away to sound substrate and
removed, or cut open and nailed flat to the deck.

STEP 3 – Board-Stock Installation
Mechanically fasten or adhere the board-stock
insulation (EPS, urethane or polyisocyanurate) to
the roof deck following the manufacturer’s
instructions. Wall-Bond 70 or 90, Instra-Stik or
equivalent may be used for adhering the panels to
the substrate.
Taper the insulation panels around drains and
scuppers, and add crickets or additional insulation
as necessary to facilitate proper drainage of water
from the roof.

STEP 4 – Details
Reinforce around drains, scuppers, flashings,
protrusions, vents, openings, etc., using ROOF MATE
Mesh embedded into ROOF MATE Butter Grade or
ROOF MATE Basecoat.
Apply ROOF MATE Butter Grade or ROOF MATE
Basecoat liberally around the area to be reinforced.
While the material is still wet, embed a strip of ROOF
MATE Mesh, centered over the detail, applying
additional material to totally encapsulate the
reinforcement fabric.

as described above.

STEP 6 – Full Reinforcement Fabric
Reinforce entire surface of the board-stock insulation
panels by embedding 40” (102 cm) wide rolls of ROOF
MATE Fabric into ROOF MATE Basecoat or Unibase.
Sandwich the fabric between two coats of ROOF MATE
Basecoat, each applied at the rate of 1 to 1½ gallons per
100 sq. ft. (.4 to .6 l/m²). If using Unibase, roll out a 4’ to
10’ (1.2 to 2.5 m) length of fabric and either spray apply
or pour Unibase evenly over the top side at the rate of
approximately 2 gallons per 100 sq. ft. (.8 l/m²).
Work the coating evenly throughout the fabric using a
broom or roller so that it is totally encapsulated,
eliminating any air pockets, wrinkles or gaps, and
allowing the fabric to conform to the surface contours.
Overlap consecutive passes of ROOF MATE Fabric a
minimum of 2” (5 cm) on each side, taking extra care to
ensure that all edges are thoroughly encapsulated, tight
and secure.

STEP 7 – Coating Application
Apply 1 to 3 separate coats of ROOF MATE, using
airless spray or roller, at the total rate of 1.5 to 4.5
gallons per 100 sq. ft. (.6 to 1.8 l/m²), depending on
warranty and/or specification requirements.
Create a self-terminating flashing by extending the
topcoat a minimum of 3” (7.5 cm) above all protrusions,
parapet walls, etc.

STEP 8 – Options
Apply walk pads, ceramic roofing granules
or Rhino Top as required to demarcate
walkways and service areas, and/or
provide non-skid characteristics.
To enhance dirt release characteristics in
problem areas, apply a coat of Acrysheen,
which imparts a slick, semi-gloss finish that
aids in maintaining a clean surface.
*Rhino Top is a tough acrylic coating that is available in both smooth and
textured formulations. It is ideally suited for horizontal surfaces that receive
regular foot traffic.
