Our vintage awnings use premium acrylic fabrics made by Glen Raven Mills. Glen Raven markets their awning fabrics under the name Sunbrella and Dickson (same type of fabric, just different colors and target markets). Glen Raven treats the fabric at the mill to be highly water repellent. Over time and with repeated cleanings, the fabric loses its water repellency and must be retreated. 303 High Tech Fabric Guard is recommended by Glen Raven Mills for regular maintenance of the fabric at least once every five years.
Powerful enough to protect fabrics in harsh environments, yet safe for the
finest fabrics, wool, silk, and fine leathers - including suede. On
outdoor fabrics, 303 High Tech Fabric Guard restores lost water
repellency and stain repellency to factory new levels. 303 High Tech
Fabric Guard resists soiling, impedes mildew formation and helps
protect against the sun's harmful UV rays.
Available in either 16 oz or 32 oz trigger spray bottles.
BEFORE USING 303 HIGH TECH FABRIC GUARD (HTFG):
Use only on cleaned material. Follow manufacturer directions to remove
all soiling, stains, soap or other cleaning agent residue. 303 Fabric
Cleaner, 303 Aerospace Cleaner, 303 Cleaner & Spot Remover and 303
Convertible Top Cleaner rinse residue free and are recommended. Test for Colorfastness: Spray a hidden area with 303 HTFG. Wipe the sprayed area with a white absorbent cloth. If any color rubs off, DO NOT USE . 303 HTFG will not change the look, feel or breathability of treated fabric. Non-toxic and odorless when dry.
Material should be thoroughly cleaned and dry. Spray until evenly wet,
overlapping spray areas. Allow treated fabric to dry thoroughly before
use. Protect adjacent areas from over spray. Immediately wipe up any
over spray before it dries. Note: 303 HTFG can be applied with an approved solvent type sprayer, brush or roller. Not for vinyl, clear vinyl, plastics, rubber, fiberglass or imitation suede.
Canvas, Convertible Tops:
Make sure not to get over spray on floors, glass, paint, or clear
vinyl. Best results on hot day, full sun. Protect from rain/dew until
dry. After drying, test by misting treated fabric with water. An area
where water doesn't "bead" either has not dried sufficiently or needs
more 303 HTFG. Dry time: 4 to 72 hours depending on temperature, humidity, and wind. Coverage: 75-100 sq. ft. per every 16 fl. oz..
