Layout Prep: run a level mark around the room 20 mm above finish height and attach a 20mm aluminum angle to the wall with nails or screws at this line.
1. Twist lock 1/8" steel hanger rods from rafters or battens at 60 cm centers
2. attach spring clips and "j" rods approximately at finished ceiling height to these hangers.
3. cut excess hanger rods off leaving 20cm extra (to be folded up prior to fitting boards.
4. install U channel long axis up (runners) through the j rods and level
5. attach U channel long axis sideways (battens) using ear clips then bend them over the runners at 40 cm centers
6. install any wiring or insulation at this point
7. lift, glue (acrylic sealant will do) and screw the sheets off to the battens with DRYWALL screws (they are Phillips head, black steel with very sharp points and will penetrate the U channels but are not what is referred to as selfdrilling and available in 1/2" or 3/4" for double sheet extended fireproofing installations)
8. taping and finishing the joints to western standards requires a great deal of skill or if this is not available, a great deal of sanding.
No base coats are available in Thailand, they sell only finish plaster (poe ypsum), generally 30 mm cloth tape is available, although lately I see 50 mm self adhesive fibre mesh tape
All this stuff is available in hardware stores.
We have a mechanical drywall panel lifter for rent in or around Rayong province ONLY or you can use 4 cheap nongs, if you can tolerate the aggravation.
