APPLICATION INFORMATION
Surface Preparation
Metal Surfaces:
Thoroughly clean the area that is to be repaired, rebuilt or lined, by using Cleaner Blend 300 (stock
#19510). All oil, grease, and dirt must be removed before applying Flexane material. All surfaces must be roughened
by grinding with a coarse wheel or an abrasive disc pad.
Rubber Surfaces
: Thoroughly clean the rubber area with an abrasive pad and Cleaner Blend 300. You may take a
grinding wheel and roughen the rubber surface. The rubber surface must be coarse and free from oil and dirt clogged
in the “pores” of the rubber. Using Cleaner Blend 300 wipe or roughen surface until the color of the rubber substrate
no longer appears on cloth. The rubber should look new or a deeper black in color.
Priming Surfaces:
On metal surfaces apply a coat of FL10 Primer and allow to dry tack free for 15 minutes. Any metal
surfaces that require the maximum tear resistance and are being used as a submersible application or wet environment
you should use both FL10 and FL20 Primer. On rubber surfaces apply a coat of FL20 Primer and allow to dry tack free
for 15-20 minutes. Use this Primer on all types of rubber and urethane surfaces. On porous rubber surfaces, it may
be necessary to do multiple coats.
Maximum Adhesion:
Sandblast the application surface using an angular abrasive to achieve a minimum depth profile
of 2-3 mils. Blast to near white finish specification SSPC-SP5 (Steel Structure Painting Council). After sandblasting,
application surface should be primed immediately to prevent oxidation.
