hi, a newbie here in this board, also a newbie with carpentry and stuffs..
I will be installing a ceiling with wooden frames, I chose to use hardiflex 3.5mm for the ceiling.. my questions are:
1. latex paint is to be used for hardiflex right?
2. will gypsum joint compound do the work to cover the joints?
3. do i still need to use tapes to cover joints before using the compound?
thanks in advance
Re: hardiflex ceiling
Yes to all.
Re: hardiflex ceiling
Just use nail intended for hardiflex or fiber cement board. Not the ordinary common or finishing nail.
Re: hardiflex ceiling
thanks for the prompt reply sirs... i will be using an air nailer with 1 inch nail to fasten it onto the timber frame.. for boysen gypsum joint compound, what kind of tape should i use? mesh tape or the ordinary paper tape? or is there a better joint compound for this? and if ordinary paper tape is to be used, am i suppose to put a thin layer of the compound first for the paper tape to adhere then a second layer of the compound to hide the tape? thank you
Re: hardiflex ceiling
i didn't know you could use nails for that. They used gypsum screws when they fixed our ceiling. I didn't like the finish.
Re: hardiflex ceiling
i was also in doubt using air nailer on hardiflex as i was thinking that the hardiflex might crack, i tried it a while ago on a small piece of hardiflex 3.5mm thick and the result was good, didn't crack, nail was driven flat enough, note that i used a nail that has a small head (a little more or less 1mm big) but enough to hold the board. after i nailed 2 portions of the hardiflex, i tried pulling the hardiflex off the wood that i have fasten it to and it didn't come off....
Re: hardiflex ceiling
I'm worried that the small footprint of the nails head might not be enough as time goes by compared to the fastening capability of the gypsum boards screws.
Nails may be OK for wall I guess, not sure for ceilings though.

Re: hardiflex ceiling
i'll consider your thought sir jarod... thanks... if nails won't do good then i'll have to use gypsum screws...
correction..
just measure the nail again, its head is 2mm and 1mm body
Re: hardiflex ceiling
I swear with the fiberglass tape (the one with mesh) but I noticed that professional drywall specialists favor the paper tape.
Re: hardiflex ceiling
fibercement boards are heavy and so is hardiflex..if you mount the whole sheet on the ceiling i wont be able to sleep in that room if that is going to serve as my bedroom.
there are specific things for this and that and we can try alternatives but in this case i will stick to gypsum screws.
fibercement boards=gypsum screws. period.

Re: hardiflex ceiling
and btw...the better partner for fibercement boards are light duty steel frames..if you make use of wooden joists then the wood will still be affected by seasonal changes, and so are the brad nails...and this repeated contraction will loosen (in theory) your nails with the boards.
and of course you cannnot use brad nails for these.
maybe you can use 1/4" wooden battens to fasten the boards instead...aesthetically pleasing pa.

Re: hardiflex ceiling
thanks for the input sir violane..
i guess i have to endure the hard work with gypsum screws.. hope that the outcome will be good enough.. just worried like what sir zepol said about him not liking the finish with gypsum screws...
Re: hardiflex ceiling
If you used gypsum screw on 3.5mm thick hardiflex, hindi naka-flush or lubog yun head ng screw. Kse manipis lang yun hardiflex mo unlike sa gypsum board 10mm thick.
If you use gypsum screw sa hardiflex w/ wooden ceiling joist mahirapan ka i-drive yun screw lalo na pag hardwood ang ginamit mo pamakuan ng kisame.
Best pa rin gamitin ang hardiflex nail.
Re: hardiflex ceiling
that's one of my major concern sir, actually my first option was to really use a hardiflex nail, but it will take a lot of time.. that's why i experimented with the brad nails, but with the brad nails sir violane has a point there.. i guess i'll have to do another test with brad nails on a full size hardiflex.. i'll also try the "stapler" kind of brad nails..

Right, full sheets would be scary not to mention hard to remove. How about cutting them up into say 2 x 2 ft tiles so less trauma when falling on you during an earthquake and/or when the fasteners fail. Anyone tried this? Not sure how good the edges would look though.
How about stainless steel pan head screws as in the below. Would these work on fiber cement and make the sections removable?
