Product Description

Easi-Lite^™ Gypsum Board is a specially formulated interior gypsum board that is up to 30% lighter than traditional 1/2" (12.7 mm) CertainTeed regular boards. It is comprised of a special, sag-resistant solid set gypsum core enclosed in 100% recycled face and back paper. Easi-Lite Gypsum Board is light weight, easy to handle and ideal for wall and ceiling applications up to 24" o.c. (610 mm) framing spacing.

Basic Uses

Easi-Lite Gypsum Board is used for interior walls and ceilings in standard residential or commercial applications. It can be used for new construction or renovations over wood or steel framing. It is typically nailed or screwed to studs spaced 16" (405 mm) or 24" (610 mm) o.c., but can be applied by laminating or with the use of an adhesive.

Advantages

• Can be used on ceilings with 24" (610 mm) o.c. frame spacing (perpendicular to framing) when water based texture is applied
• Scores and snaps with less dust
• GREENGUARD Children & Schools^SM certified

Decoration

CertainTeed Easi-Lite^™ Gypsum Board accepts most types of paints, texture and wall covering materials. The surface shall be primed and sealed with a full-bodied latex primer before applying a final decorative material. This will equalize the suction between the joint compounds and the paper surface. For best painting results, all surfaces, including joint compound, should be clean, dust-free and not glossy. If glossy paints are used, a thin skim coat of compound over the entire surface, Level 5 finish, is recommended to reduce highlighting or joint photographing. This method is also recommended for areas of critical sidelighting of natural or artificial light sources. A sealer application under wallpaper or other wall covering is also recommended so the board surface will not be damaged if the covering is subsequently removed during redecorating. Joint treatment must be thoroughly dry before proceeding with primer-sealer application and final decoration.
