55-7230 Gilsonite Solution-Low Viscosity

 

GENERAL DESCRIPTION

 

Pruett-Schaffer’s #55-7230 is an air-drying, solvent based, modified asphaltic coating.  It may be applied by brush, spray or roller.  It exhibits good surface wetting properties for difficult to clean substrates and corrosion & water resistance. It provides a cost effective alternative to toxic coal tar based compounds for protecting steel, aluminum or concrete from normal environmental conditions.

 

RECOMMENDED USES

 

 It is recommended for general maintenance on steel or concrete structures wherever normal interior or exterior atmospheric conditions exist. It is designed for use as a corrosion preventative & waterproofing compound over concrete & metal substrates, both above & below grade, exposed to humidity, salt water, oil, acids & alkalis. The coating is not normally topcoated & is not recommended for exposure to solvents, gasoline or other fuels.

 

 

SURFACE PREPARATION

 

For best performance, new metal substrates should be clean, dry, & free of oil/grease (excessive oil & grease will cause the coating to remain soft) Concrete should have all form release oils, curing membranes & dirt removed. This coating is very tolerant of less than perfect surface preparation. Feather all rough or sharp edges.

 

THINNING

 

Under normal conditions no thinning is necessary.  Thin if necessary for spraying with xylol or toluol.  Add a little at a time with constant gentle agitation to a maximum of 5% by volume.  In ambient temperatures over 85 0F Mineral Spirits, Aromatic 100 or Aromatic 150 may be used if “dry spraying” occurs.

 

APPLICATION EQUIPMENT

 

May be applied by brush,conventional, air-assisted, or airless spray.   Brushes should be of polyester or nylon construction.   Apply to 4.0 mils wet film thickness, to achieve 1 mil dry film thickness.

DRYING TIME

 

Dries tack free in 30 minutes at 70 0F. 

 

CLEANUP

 

Clean equipment with mineral spirits, xylol or toluol before the film dries.
