I'm doing a drywall using gypsum board. The sides are easy to tape (mesh) and putty because the board has tapered edges to accommodate the tape.
How do you do the top and bottom sides since they don't have tapered edges? On youtube and foreign sites/forums, they recommend using PAPER TAPE for the joints, but I've looked everywhere and can't find it. I don't want to use the mesh tape because it will bulge. Painters are recommending polytuff (polyester filler), but won't that crack also because it's not flexible?
I would like to try Elastomeric Putty, which is recommended for cracks on concrete, and since it's elastomeric, it has a certain stretch or flexibility to resist (I'm assuming) cracking. Would this work?
BTW, what kind of putty do you use? Cheapest I've seen are Boysen Gypsum Putty, but the painters are insisting on using BORAL POWDER. They claim it dries easier, but what about the quality? I don't want to do shortcuts and realize in a year that I will have to repaint everything again.
Your drywall and ceiling is made of gypsum board. Used only gypsum putty. I prefer Boral Premix gypsum putty since timplado na siya. I used either paper tape or mesh tape. Mesh tape is commonly available sa mga hardware. Paper tape sa mga dealer/distributor ng gypsum at ficem board lang ako nakakabili.
Sa installation ng gypsum board I always leave a 1/8" (3mm) gap between board. Pag closed gap hindi na pumapasok yun gypsum putty sa dugtungan. Mas prone sa hairline crack.
Sa dugtungan ng gypsum board na hindi naka tapered, nilalaparan lang namin yun masilya around 10-12". Hindi mo na masyadong visible yun bulge sa wall or ceiling.
Anong klaseng boral ba ginagamit ng mga karpintero? Kapag nagpapabili sila "boral powder" lang nakalagay. Eh sinearch ko sa google madaming klase ng products yung boral.
Eto yung tumitigas pag binasa diba? Pwede din ba ihalo yan sa latex paint?
Deds na yata tong forum...
Mostly sealant ang pinapalagay sa mga Japanese company sa mga board na naka terminate sa structures or masonry wall para di mag crack. pero kailangan magaling yung mag aaply para di mag bulge at straight yung application. You can also try to put ceiling trim.
