Which Fiberglass Cloth to Choose?

Depending on the job at hand, we offer a few types of fiberglass cloth to choose from and different cloths are used for different jobs. They are available in different widths and are sold by the roll or yard.

Mat– This mat is used for parts and is great for not showing fiberglass patterns through gelcoat. Mat has many small fibers thrown together on a binder and is the most used, basic cloth. There is no specific direction to the fibers, making them strong and light. Sold in ¾ oz up to 2 oz thickness.

Woven Roving-This weave has long fibers weaved together like a cloth. It is extremely thick and durable making it heavier than other fiberglass materials. This often shows pattern through gelcoat and is used for heavy duty items. Sold in 18 and 24 oz thickness.

Double Bias Non Woven- 1808, the first number is the woven roving thickness (18oz) and 08 is the mat thickness (3/4 oz). This is a combination of woven roving on one side and mat on the other, making it very durable and usually used for boat and house decks as it is very rigid.

Fiberglass Cloth– This is sold in 4, 6, 8 and 10 oz thickness an is very fine. While being rigid it also used for anything that is see-through, such as surfboards as it’s thin, lightweight, and shows well with clear resin.

How to Paint your Fiberglass Pool Steps

The finish of your fiberglass pool steps can fade after years of use and exposure to pool chemicals and the weather. If you notice that your pool steps are looking tacky it might be time for you to repaint them. There are a couple of ways you can go about doing this.

You can use Gel Coat if your pool steps currently have gel coat or bare fiberglass. We offer two different brands Gel Coat by Sea Hawk and Ultra Plus Brushable Gel Coat by FGCI.

See the article How to Apply Gelcoat’ for more details on how to use gel coat.

Pool Guard EHB

The second option would be to use the EHB Pool Guard Epoxy Pool Paint by National Pool Finishes. This product is self-priming, and it is formulated to give maximum protection as well as having fill qualities for imperfect pool surfaces. It is the only pool paint product we offer that is safe for application over fiberglass, and it comes in a variety of colors. 

Surface Preparation: Water blast the surface to remove all loose paint, dirt, oils and grease. Clean with a Tri-Sodium Phosphate (TSP). Etch the surface with a 15-20% solution of muriatic acid. Then thoroughly rinse with TSP & flush with plenty of fresh water and allow it to dry thoroughly. Allow 5 days for complete cure before filling pool with water. Add 1 day for every day of rain.

Both options are perfect for any do-it yourselfer and they will provide long lasting results if applied correctly.
