Product Overview
Description
- All purpose drywall compound provide high- quality drywall joint finishing with ready-to-use convenience
- Used for embedding tape and for concealing and finishing joints, fasteners, and trim accessories on gypsum wallboard, in applications where the use of a single compound for both taping and finishing is desired
- Can be applied manually or with mechanical tools
- Factory mixed to ensure uniform consistency and to save time on the job
- Used for taping, covering and finishing coats on wallboard joints, for concealing fastener holes and corner bead, and for repairing cracks and holes
- Sands easily and feathers to smooth edge
- Liquid content is carefully controlled at the factory to ensure minimum shrinkage
- Approximate coverage in kilograms of compound per 100 m2 (1000 ft 2) of drywall panel is as follows: Regular - All- Purpose Compound (3 coats) 55-68 kg
- 282 sq.ft. of drywall
- Rotate stock to avoid aging problems
- Wallboard joints are normally finished using three coats of compound; the first to embed the tape, the second to cover the tape, and the third to finish the joint
- These compounds can be used for all three coats
- Apply the first coat to the joint in a band about 64 mm (2-1/2") wide
- Centre tape over joint and embed with a broad knife
- Allow to dry for 24 hours
- Apply second (cover) and third (finishing) coats, allowing each to dry thoroughly
- Sand between coats, if necessary
- Feather edges of each coat 50 mm (2") beyond the previous coat
- Finished joint should be about 350 mm (14") wide
- Allow to dry for 24 hours before sanding
- Use 120 grit sandpaper for the Regular and 150 grit for the Lite and Semi-Lite on a hand or pole sander
- Do not sand the surface wallboard paper
- Note: to avoid dust, joints can be finished by wet sanding or sponging rather than dry sanding
- If dry sanding, ventilate the area and wear eye protection and a respirator
- For best results, apply a primer-sealer prior to painting or wallpapering
- For severe lighting conditions, or if a gloss paint is to be applied as the finish coat, it is recommended that the entire surface of the wallboard receive a skim coat of compound before applying the primer-sealer
- This will assist in equalizing the rate of absorb- tion of the gloss paint and help to avoid flashing at the joints
- Re-mix before and during use, if compound has separated
- To thin, add no more than 40 ml (1.5oz) of clean water per kilogram of compound
- Mixing by drill motor, particularly at thinner consistencies, may entrap air in the mix, possibly resulting in "pin holes" in the finish
- Mixing at low RPM or by hand will minimize air entrapment
- Approximately 24 hours depending on temperature and relative humidity
