Cosmetic Care & Maintenance
Canvas
Boat canvas is in most cases subjected to more severe punishment than
practically any other type of material. Moisture, dirt and chemicals
from industrial fallout, heat, ultraviolet rays and salt water are all factors
which accelerate the deterioration of your boat canvas.
These elements can cause serious damage if left unchecked.
The boat top and other canvas supplied on your Regal boat are
manufactured from top quality materials to provide you with years of
trouble free service. The following information on the care, cleaning
and proper storage of the fabrics and fasteners that make up your
marine canvas is being provided to help you maintain the appearance
and ease of operation.
Sunbrella is used on most Regal tops, aft curtains, camper enclosures,
bow tonneaus and cockpit covers. Sunbrella is a woven fabric made
from 100% solution dyed acrylic fiber. It is color fast and will withstand
long term exposure to the sun (ultraviolet rays) without excessive fading.
Sunbrella is a woven fabric. Even though it is treated with water
repellency some "misting" through the fabric is typical. With new
canvas, the greatest potential for leakage is through the sewn seams.
Because Sunbrella and the long term thread used is synthetic, the holes
created by sewing will not swell up and seal when exposed to water as
cotton does. Usually the movement of the fabric in use will move the
fibers enough to seal the holes. You may apply Apseal or Uniseal to
the seams to speed up this process.
When the canvas is new, the fit will normally be tight. It is designed this
way because Sunbrella stretches as it ages, The initial tight fit allows
for a suitable fit for the life of the canvas. The Sunbrella fit will vary
slightly in the heat, cold, and rain.
