For METAL SURFACES, thoroughly clean area to be repaired, rebuilt, or lined with Devcon® Cleaner Blend 300. Remove
any oil, grease, or dirt. Roughen surface by grinding with a coarse wheel or an abrasive disc pad. To prime this surface,
apply a coat of Devcon FL-10 Primer and allow to dry tack-free for 15 minutes. If the metal surface requires maximum tear
resistance or is exposed to moisture, or if submerged in water, use Devcon® FL-10 and Devcon® FL-20 Primer.
For RUBBER SURFACES, thoroughly clean area with an abrasive pad and Devcon® Cleaner Blend 300. Surface can also
be roughened with a grinding wheel so that it is coarse and free from oil and dirt that may clog the "pores" of the rubber.
Wipe or roughen surface with Cleaner Blend 300 until the cloth no longer picks up the color of the rubber. The rubber
should appear new or deeper in color. To prime this surface, apply a coat of Devcon® FL-20 Primer and allow to dry tackfree for 15-20 minutes. Use Devcon®FL-40 Primer on "hard-to-bond" rubber surfaces as this gives ultimate peel
resistance. Multiple coats may be necessary for porous rubber surfaces.
For MAXIMUM ADHESION, sandblast the surface with an angular abrasive until a minimum depth profile of 2-3 mils is
met. Blast to near-white finish specification SSPC-SP5 (Steel Structure Painting Council). Prime surface immediately after
sandblasting to prevent oxidation.

Mixing
Instructions:

---- To ensure proper cure speeds and hardness, mix Flexane at a temperature between 65°
F-85° ---F.
FOR 1 LB. UNITS
1.Add hardener to resin.
2.Vigorously mix with screwdriver or spatula for two minutes, while continuously scraping material away from sides and
bottom of container.
3.Transfer the mixed material to the plastic container (included in kit).
4.Wipe spatula clean, and stir again for two more minutes.
