A nylon paint brush or a tapered sponge brush is a good choice for roof patching or applications with inside corners etc.
Do not use course bristle tooth brush, tampico or heavy 3 knot roof
brushes--they will produce unwanted ridges instead of a smooth surface.
Short nap paint
rollers are used for flat areas such as roof decks, floors and
walls. Long nap roller covers will give a heavy texture that may be
desired on wall surfaces but are not recommended for surfaces such as roof decks
where waterproofing is the purpose of the application. Select a
"heavy duty" nine inch paint roller with an extension handle. Use a
short nap roller cover (1/2" or less) to provide a smooth application.
Gas engine powered airless
spray equipment is an excellent choice for applications such as roof
decks and parapet walls on commercial buildings. Airless spray equipment
is usually the choice for coating the Recycled Rubber "in house"
factory applications, where an existing air compressor is available.
AIRLESS SPRAY equipment must produce a minimum of 2000 PSI and pump a minimum two gallons per minute with a .039 tip. Most sprayers require a minimum of 8 HP. Call for more information of this and other recommended equipment. Tools and equipment are cleaned with water.
Texture Spray
equipment is the best choice for sidewall and foundation applications
where texture is more important than the positive waterproofing required, such
as for roof applications.
Do not thin the products to lower the
viscosity.
For selecting the proper pump size for the spray equipment:
Spray tip size for airless sprayers: Recycled Rubber Roofing = .039
#100 Vap-R-Lok = .031
