Liquid
Membrane Coating |
|
RV Roof Aid™ is a two
component Aliphatic Urethane that can be applied in thick
films to produce a durable membrane-like coating over all
types of rigid and flexible substrates. It is ideal for
recoating rubber, aluminum or fiberglass RV roofs. The
urethane chemistry of RV Roof Aid™ ensures an
easy to clean surface. Application is fast with a squeegee,
foam roller and brush. The product will self-level to
produce a smooth glossy film. |
|
Mixing Directions |
- Add part B into Part A incrementally and mix using a
drill mixer.
- Use a rubber spatula to scrape all of the material
from sides and bottom of container B.
- Use spatula to scrape sides of mixed container to
ensure that the entire contents are mixed uniformly.
- Do not take more than a few minutes on this
procedure since the chemical reaction starts immediately
and the mixed product must be applied within 60 minutes
(depending on temperature).
- Once applied to a surface the available working time
is an additional 2 hours.
- Only mix one container at a time, and then apply
before mixing another.
- Overlaps will still blend in if application is
within 2 hours of previous one.

Application Instructions |
Surface Prep:
- Surface should be dry and free of dirt or oil or
other contaminants.
- Smooth metal and fiberglass surfaces should be
sanded lightly to improve adhesion.
- Ambient temperature must be 50°F or higher.
- Prepare surface prior to mixing product.
- Prime Substrate with
Proflex Primer® F1500 Clear
- Allow primer to cure 2-3 days
prior to application of
RV Roof Aid™.
If you wait longer than 3 days you will need to sand the
Proflex Primer® F1500 Clear
prior to applying RV
Roof Aid™.
|
Application:
- Mixed product can be poured onto surface in a
serpentine pattern, then spread using a rubber edged
squeegee followed by rolling with a short nap roller.
- Product will self-level but can be applied to sloped
and vertical surface using a roller.
- A brush can be used for small areas.

How much
RV Roof Aid™ to Use |
|
RV Roof Aid's™ unique formulation
produces a tough yet flexible membrane in one coat. The
resulting membrane thickness is determined by the spreading
rate i.e. the number of square feet of surface that were
coated from one gallon of product. For best appearance and
durability a thickness range of 20-40 mils is recommended.
(A sheet of copy paper is 4 mils thick) |

|

|

Example: How many gallons of RV Roof
Aid™ are needed to coat 200 sq. ft. of roof and result in a
20 mil thick membrane: |
200 ft2 = 2.7 gal.
75 ft2/gal |
|
A cured RV Roof Aid™ film should not be
top coated without first sanding the old surface to improve
intercoat adhesion. A dry edge should also be sanded before
overlapping with wet material. |
|
Care & Maintenance |
|
Periodically check and remove from your roof surface any
debris, i.e. pine needles, leaves or twigs. You should
clean your RV Roof Aid™ roof twice a
year with a solution of detergent and water. |

Notes: |
|
This is a Polyurethane product that is nearly 100% solids
and can therefore be applied in thick films. |
|
Although the product will cure, even when several inches
thick, it will develop trapped gas bubbles within. Urethanes
produce CO2 (carbon dioxide) gas as a by-product of the
chemical reaction that converts liquid to solid. This gas is
able to escape if the applied film is 30 mils or less thick
(7 sheets of paper) and produce a glassy and smooth film.
Heavier films will trap some of the gas resulting in a
dimple surface as well as bubbles within the film. |
|
To achieve smooth glossy films – apply film at 30 mils or
less. |
|
or |
Add some solvent (up to 20% by volume) to reduce
viscosity.
Use MEK (methyl ethyl ketone) |
