BMPRIME™ ADHESIVE PRIMER SEALER FOR BUSES & RVS
PRODUCT DESCRIPTION
|
BMPRIME™
is a transparent white, acrylic elastomeric, waterproof adhesive Primer Sealer
designed as the Primer Sealer for THERMCOTE/BM™ for Bus &
Recreational Vehicles roofs. A waterborne, latex-based, high resin content
formula that contains no fillers so that it waterproofs and provides excellent
adhesion to most types of surface. A high resin content plus the addition of
special adhesive chemicals enables BMPRIME™ to waterproof, bond and
seal the surface together preparing it for the application of THERMCOTE/BM™.
Excellent penetrating characteristics enable BMPRIME™ to permeate into
the substrate providing a permanent bond to the finish coat. On non-porous
substrates, the high resin content provides excellent adhesion to the surface
then forming a tight bond to the finish coat. The bond that is formed between BMPRIME™
and the THERMCOTE/BM™ finish coat eliminates any possibility of
moisture under the finish coat thus extending the coating’s and roof’s life
considerably. |
PRODUCT USES
|
BMPRIME™
is recommended for all Bus & Recreational Vehicle roofs. Roof Surface must
be well drained and cannot hold any ponding water. Excellent adhesion on wood,
shakes, plywood, primed metal, galvanized, aluminum, tin, copper, asbestos,
asphalt, urethane, polyester, styrofoam, fiberglass, rolled roofing, modified
bitumen membranes, mineral surfaced roofing, concrete, masonry, and various
other substrates.
- Excellent Adhesion and Bonding
- Easy Application & Water Clean Up
- Safe for the Environment
|
SURFACE PREPARATION
|
A primer sealer coat of BMPRIME™ is required for the 5 Year Limited
Warranty on the THERMACOTE/BM™, Bus & Recreational Vehicle
Coating System. Prepare surface by thoroughly pressure washing with a water
and chlorine solution using at least 1500 P.S.I. to remove any previous
coatings, dirt, grease, and other foreign materials, especially mold, mildew and
algae.
BMPRIME™
will resist mildew growth but will not kill mildew already on the surface. Apply
only to a sound, well-prepared surface. Prepare all rust and corrosion with OXIPRIME™,
Red Iron Oxide Primer Sealer before the application of BMPRIME™.
Patch any holes, cracks, valleys, etc., with THERMAPATCH™, Waterproof
Caulk and Sealant. Tape and seal all seams with POLYMESH™, Polyester
Fabric Tape.

APPLICATION PROCEDURE

Stir
well before using. Do not thin. Use product as is. Do not apply when
temperatures are below 45 degrees Fahrenheit or when humidity is very high. Do
not apply when primer will be subjected to rain or heavy dew before it has had
enough time to dry (approximately 4 to 6 hours). Drying time will vary depending
on temperature, humidity & location. Apply using brush, roller or spray. Use
at least a 1 gallon per minute piston type airless sprayer with a minimum tip
size of .025. Spread uniformly.
Wait at least 12 hours before applying THERMACOTE/BM™. Be sure to coat
over BMPRIME™ with THERMACOTE/BM™ within 72 hours or surface
may become contaminated.
