Premium 4oz E-glass fiberglass cloth for lightweight surfboard laminations in Sri Lanka. Ideal for shortboards and inner layers where low weight and clean flex matter. Wets out quickly, drapes well over rails, and suits epoxy or polyester. Supplied in 100 m × 1 m rolls.
4oz fiberglass cloth is the standard lightweight reinforcement used for surfboards, small composite parts, and repairs. It provides a smooth finish with minimal resin absorption, making it ideal for shortboards, deck patches, and fine laminations where weight matters.
The tight weave wets out quickly and conforms easily to curves, helping achieve a clean lamination with good strength-to-weight performance. Suitable for polyester or epoxy resin systems.
What is 4oz fiberglass cloth used for?
Primarily for lightweight surfboards, shortboards, and performance builds where reduced weight and controlled flex are important.
Is 4oz strong enough for surfboards?
Yes, especially for shortboards. Many builders use 4oz on the bottom and double layers on the deck for added strength.
Can I combine 4oz with 6oz cloth?
Yes. A common layup is 4oz bottom and 6oz or double 4oz on the deck for balanced durability.
Does this work with epoxy resin?
Yes. Compatible with epoxy, polyester, and vinyl ester resins.
How many boards can I laminate from one roll?
Depends on board size and layup schedule, but a 100m roll is suitable for continuous production in small to medium workshops.
Is this suitable for tropical climates like Sri Lanka?
Yes. Store in a dry area to prevent moisture contamination before lamination.
