Gold Bond Gypsolite Plaster

Description

Gold Bond® BRAND Gypsolite is a lightweight gypsum basecoat plaster mixed at the mill with correctly sized and proportioned perlite aggregate, requiring only the addition of water on the job. It is manufactured to be trowel-applied over Gold Bond® BRAND Kal-Kore Plaster Base or metal lath.

Advantages

Uniform Strength and Hardness
 Uniformity is assured through exact proportioning and thorough mixing of graded perlite and gypsum plaster at the mill. Gypsolite provides a uniform base for the finish coat.

Lightweight
Gypsolite weighs less than half as much as sanded gypsum plaster, thus reducing the dead-load on framing.

High Insulating Value
Gypsolite has a "k" factor of 1.5 which provides about 3 1/2 times the insulating value of sanded plaster.

Limitations
When used over metal lath, a sand float finish should be specified. A smooth-trowel finish is not recommended since the combination of a relatively soft (perlite aggregated) basecoat and a hard (smooth-trowel lime/gauging) finish has the potential for cracking and spalling of the finish coat.

Fire Resistance
Gypsolite has excellent fire-resistive qualities and generally provides fire ratings higher than sanded plaster.

Specification Reference
ASTM Designation C 28 for "Gypsum Plasters".

Bag Weight
80 lbs. (36.3 kg)

Applications
