Application procedure
1) Incorporate supplied catalyst using drill and mixer shaft by
following label directions.
When temperatures are mild you should allow the product stand at least
1/2 hour before using.
2) Apply masking tape to perimeter of roof or wherever straight edges
are desired.
Tape can also act as catch basin for sags if only one edge is attached
to roof and rest is formed into shape of a gutter.
3) Pour some material on roof and use squeegee to distribute over
surface.
Follow with roller to even out the wet film. Product will self-level
when sufficient material has been applied.
On an RV use a brush around vents, ladder, and antenna. Brush and roller marks will
disappear when sufficient material is applied. Work from front to rear.
4) Masking tape should be left on until rubber is solid enough to be
touched.
How long will it take for the Rubber to cure?
Cure time is controlled by temperature. At 70° F. and above it will take
approximately 14 hours for the rubber to feel solid to the touch.
Heavier films may take longer. The lowest temperature at which any cure
takes place is 55°F. At that temperature it would take 3-4 days for the
rubber to feel solid to the touch if the wet film was not more than 35
mils. Thick films take longer to cure.
Must the air/surface temperature be above 55°F before Liquid Roof® or
Liquid Rubber® can be applied?
No, but temperatures above freezing are preferred for physical comfort.
Liquid Roof® and Liquid Rubber® will waterproof as soon as they are
applied but no cure will take place until the temperature exceeds 55° F.
What effect does high relative humidity or freezing temperatures have
on Liquid Roof® and Liquid Rubber®?
Liquid Roof® and Liquid Rubber® can be applied under high humidity
conditions as long as the surface is dry and its temperature is above
the dew point. The solvent evaporation is governed by temperature only
and is not influenced by relative humidity. If the temperature drops
below freezing after Liquid Roof® or Liquid Rubber® have been applied no
damage will result. The rubber will slowly stiffen as the solvent
evaporates and begin to cure when the temperature exceeds 55° F. The
ultimate physical properties of the rubber membrane will always be the
same regardless of the length of time needed to reach the full cure
stage.
How much time is available to work with Liquid Roof® and Liquid
Rubber® after the catalyst has been mixed in?
On a hot day, above 80° F., the working time will be approximately four
hours until the rubber becomes noticeably thicker and more difficult to
apply. Working time is considerably longer at lower temperatures. The
rubber will thicken faster in direct sunlight and when liquid level is
low in the container scrape liquid from sides. Put container in a cool
place when longer working time is needed. If material is
refrigerated (below 50 degrees F.) after catalyst was added it can be
saved and used even weeks later.
How soon can I use my RV after applying Liquid Roof®?
As soon as the rubber has solidified and surface is not tacky to the
touch.
What are the acceptable substrates to be coated with Liquid Roof® or
Liquid Rubber® The following
are recommended substrates to coat:
EPDM Rubber Membrane, Concrete (except foot traffic surfaces), Urethane Foam, Primed Wood, Fiberglass, PVC Sheet and Pipe, Acrylic Sheet, Sponge Rubber Insulation Metal: Coated or Galvanized Steel, Weathered Aluminum, Weathered Copper
What are the substrates Liquid Roof® & Liquid Rubber® should not be
used on? Built up Asphalt
Roofs, Asphalt Shingles, Modified Asphalt Rolled Roofing, Stainless Steel, Glass, Silicone Caulk,
Foot Traffic Surfaces, Hypalon Membrane
