The tips for painting fiberglass surfaces need to be followed carefully to achieve the best results in painting of fiberglass.
Fiberglass is a fiber reinforced polymer which constitutes a plastic matrix
reinforced by glass fibers. It is strong and light and is used for many
purposes. This material finds its utility in boats, automobiles, pipes, water
tanks, roofing and cladding. Certain tips for painting fiberglass surfaces
need to be known in order to exploit this material to its fullest.
Reasons for painting a fiberglass surface: There are reasons why a
fiberglass surface needs to be painted. Depending upon the type of resin used,
fiberglass surfaces can fall prey to sun damage or invasion of water. In case
water infiltration takes place, the surface will be prone to blisters or bubbles
and this might cause a lot of damage. Sunlight makes the surface crumble and
brings forth a lot of trouble. To curb these problems and also to make a
fiberglass surface look good, it is often painted.
Preparing the Surface: Preparing the surface for painting involves the
most important part of the tips for painting fiberglass surfaces. The humidity
of the atmosphere should not exceed 60% and the temperature should be within 19°
to 35° Celsius. The paint will take a longer time to dry if the temperature is
lowered. In high temperatures, the paint will harden instantly and leave no time
to smoothen out bumps or uneven levels. Therefore, it is best to maintain an
A surface which is free from grease or oil will provide for smooth painting.
Also, there needs to be as little blemishes as is possible or else it will show
up through the paint. Glossy surfaces will not allow paint to adhere to it and
therefore the surface needs to undergo sanding. Carrying out this process with
the help of wet sandpaper is a safe bet.
To paint over a fresh fiberglass surface, a primer should be used. Rough
sanding should be carried out on a pre-primed surface. If a surface already has
the first coat of paint, it is advisable to go in for a fine sanding. In case
you are painting over succeeding layers, use wet sandpaper to rub the surface
before you start painting. The primer serves a dual purpose while painting a
fiberglass surface. It acts as a barrier against water and also helps the paint
adhere firmly to the fiberglass.
Methods of painting: The tips for painting fiberglass surfaces should
be followed to get the best results. There are two ways in which a fiberglass
surface can be painted. One method is the spray painting and the other is the
roll and tip method. In the first method, a spray gun or compressor is used to
apply paint over the surface. This method involves an amount of practice and
requires only one person to do the job. Lesser time is required for the drying
The roll and tip method requires very little skill and involves lesser risks
of inhaling fumes. However, it has a few disadvantages over the spray method as
it is more time consuming and the paint applied by the roll and tip method takes
a longer time to dry.
