Asbestos-use in plaster overlaps this period. Taping drywall joints dates from as early as the 1920s. Most of what I've read seems to indicate that the most likely sources are things like insulating boards, sprayed cements, Artex etc. Drywall systems that may contain asbestos - at least in finishes, taping joint compounds, skim coats, or in systems that applied plaster over gypsum board date from about 1910 through the early 1980s in North America (1982 in Canada). There is no decorative plaster or textured paint (like Artex), insulating board, cement or anything like that.Īm I worrying unecessarily? (Considering I've already removed some old screws and battens etc!). Taking out one old rawplug caused a chunk to fall off about 3 inches across, the plaster looked white rather than brownish in part of it but the surface didn't look as though any filling or patching had been done there.did the old plaster vary like that or are my eyes playing tricks? Plasterboard, drywall, and also joint compound used on wall and ceiling surfaces and at joints in the 1960s and up into 1986 might indeed contain asbestos. For work other than removal (for example preparing a non-friable asbestos wall for painting or drilling a hole for piping or electrical cabling) you do not. It's had a few holes filled in the past probably with some proprietry filler compound but other than that I'm guessing it's the original stuff. I have to to quite a lot of hole drilling to mount the shelf uprights.Īnyway, was asbestos ever used in wall plaster? The house was built in about 1880-1890.

#Asbestos in plaster wall upgrade
If your plaster walls have seen better days, you may be ready to upgrade to drywall panels. Modern plaster products and modern drywall and taping compound do not contain asbestos.
The plaster dries to form a hard, smooth surface suitable for finishing, first. The lath is then embedded with three layers of wet plaster. Four-foot-long strips of wood lath, typically 1-inch wide, are nailed directly to the open wall studs. Although no wall material samples were taken and analyzed. Lath and plaster refer to an interior wall construction technique that typically predates the 1940s. I'm currently redecorating and putting up some shelves. Lath and plaster walls can be updated to drywall by covering them, or replacing them altogether. 1 Hello, Ive recently done an asbestos survey on our property which showed that artex coating on ceilings contains asbestos.
