ACRYLIC ROOFING:  BASIC PROCEDURE

Before beginning the following procedure, prepare the roof as described on the preceding pages. Next, if there are any inside corners, outside corners, skylights, pipes, or drains, flash as described later in this manual. Finally, apply acrylic as described below.

To achieve adequate membrane thickness, it is essential to apply at least one gallon of Conservation Technology Acrylic for every 20 square feet of roof surface. Although the following procedure describes a four-coat process, additional coats may be necessary to apply the proper quantity of acrylic.

 

attach metal

STEP 1:  Attach a metal drip flashing at the roof edge. Select
a flashing without a raised lip that can restrict water runoff.

 

 

apply first coat to metal

STEP 2:  Apply a heavy coat of acrylic
over the flashing and onto the roof surface.

 

 

aply fabric to metal

STEP 3:  Embed 6" reinforcing fabric in the wet acrylic,
stopping approximately 1/2" short of the roof edge.

 

 

topcoat metal

STEP 4:  Roll a second coat of acrylic on top,
completely saturating the fabric.

 

 

first coat transition

STEP 5:  Using a short roller, apply a coat of acrylic at least
4" up the wall and 4" onto the adjacent roof surface.

 

 

apply fabric to transition

STEP 6:  Embed 6" fabric into the wet acrylic so that it
extends 3" up the wall and 3" onto the roof surface.

 

 

topcoat transtion

STEP 7:  Roll a second coat of acrylic
on top, completely saturating the fabric.

 

 

coat wall

STEP 8:  Using a full-length roller, re-apply acrylic over the
wall fabric and continue upward to the desired flashing height.

 

 

apply fabric to wall

STEP 9:  Embed a strip of fabric in the wet acrylic,
overlapping the first fabric by at least an inch.

 

 

topcoat wall

STEP 10:  Roll a coat of acrylic on
top, completely saturating the fabric.

 

 

base coat for first strip

STEP 11:  Apply a heavy coat of acrylic to the roof
surface, extending approximately 44" from one end.

 

 

apply first strip

STEP 12:  Unroll 40" fabric into the wet acrylic,
making sure there are no wrinkles or bubbles.

 

 

topcoat first strip

STEP 13:  Top-coat with a heavy coat of
acrylic, completely saturating the fabric.

 

 

base coat second strip

STEP 14:  Apply acrylic 40" beyond the edge of the
fabric, and re-apply acrylic over the last 6" of fabric.

 

 

apply second strip of fabric

STEP 15:  Immediately embed 40" fabric into the
wet acrylic, overlapping the first fabric by 3" to 4".

 

 

top coat second strip

STEP 16:  Top-coat with a heavy coat
of acrylic, completely saturating the fabric.

 

 

base coat last strip

STEP 17:  Continue the process of layering
acrylic-fabric-acrylic, reaching the other end of the roof.

 

 

apply last strip of fabric
STEP 18:  Trim the final fabric so that it will extend just
short of the roof edge, and unroll it into the wet acrylic.

 

 

top coat last strip
STEP 19:  Top-coat with a heavy coat of
acrylic, completely saturating the fabric.

 

 

third coat

STEP 20:  Wait at least 24 hours for the base
coats to dry. Then apply the first finish coat.

 

 

fourth coat

STEP 21:  After the first finish coat has dried,
apply the second finish coat perpendicular to first.

 

 

pressure wash

STEP 22:  After five years, pressure wash, inspect the
roof, and repair any problem areas with acrylic and fabric...

 

 

maintenance coat

...Then apply a maintenance coat of acrylic at the rate of
one gallon for every 80 square feet of roof and flashing.
