Coverage:
Every square meter (m2) of the matt weighs about 450 gram
A 40kg roll of fibreglass mat equals about 88 square meters (m2)
To the 80m2 of 40kg roll of fibreglass mat covers will actually provide a lining for about 70m2 of pool surface area after an allowance for overlapping and a bit for wastage are included.
Other materials used with matt:
Resin that is used as a "primer" and "laminating glue" for the matt onto the interior surface of the pool
Top Coat that "protects" the hardened resin and fibreglass matt from water and to provide a glossy finish
Optional, but highly recommended: Clear surface tissue that is laminated on top of matt to ensure a stronger, smoother surface of fibreglass lining for your swimming pool.
