From the 1700s all the means through the forties , lath and plaster was the interior bulwark building method acting of pick . Builders smash thin , nearly spaced airstrip of woods ( lath ) to palisade studs and then smoothed multiple coating of plaster over the lath to form bland wall surfaces .
When dry wall panel amount on the tantrum in the 1950s , they soon supervene upon lath and plaster of Paris as a quicker , easier install option .

1. Dense lath and plaster provides some insulation, fire resistance, and soundproofing.
Powdered lime , Amandine Aurore Lucie Dupin , and fibers ( often horsehair ) were the traditional constituent used in the creation of lath and plasterwork walls . A typical lath and cataplasm wall required a minimum of three coats of plaster , resulting in a dull , tilt - hard coating near 1 column inch thick . In combination with the lath framework beneath , lath and plaster together add up to about 1¼ inch thick . This heaviness offer some distinct benefits :
2. Lath and plaster construction does, however, have its downsides.
For all its ambience , character , andpositive acoustical trait , there are good reasons why lath and cataplasm fall out of vogue .
3. Most houses built before 1940 have lath and plaster walls that need regular inspections and repairs.
If you hold up in a menage built before 1940 and the walls have n’t been updated , they are most likely adhesive plaster . As long as they ’re in decent condition ( in other row , not falling away from the lath in chunks ) , you may opt to result them as they are . For many , plaster wall are a bountiful part of anolder home ’s historical magical spell , and they ’re well deserving keep intact . If this is the example , the best fashion to ensure that the wall remain in good shape is to on a regular basis scrutinise them andrepair cracksas soon as you mark them .
Patching adhesive plaster wallscan be as simple as skimming over small cracks with new plaster . Sometimes , however , repairs can be more involved and may require removing loose sections of plaster and filling in the smudge using a standardThree - Step Plaster Method . While skimming over small wisecrack is something a ready to hand homeowner can do herself , replastering full section is a job for a professional plasterer .
4. There are three main types of lath, and they are used for different applications.
The primary type of lath used with adhesive plaster are metal lath , wood lath , and careen lath . Each has pro and cons that make them best suited for particular billet .
Metal lathlooks much like a screen . Not only is the material reproducible , it also provides added fire aegis .
Wood lathhas been used in construction for more than 400 years . Also calledlath airstrip , these narrow spline are typically 2 inches broad and about 4 foot long , with rough surfaces that help secure the adhesive plaster to the lath .

Rock lathis made from plasterboard or dry wall . It ’s typically ⅜ in thick , 16 inches wide , and 48 inches long . Rock lath generally has small holes or a textured surface to improve adherence of the plaster .
5. Lath and plaster walls can be updated to drywall by covering them, or replacing them altogether.
If your plasterwork walls have seen unspoiled day , you may be ready to upgrade to drywall panels . This is unremarkably done as part of a larger remodeling task and often includes the addition of raw wiring and insulation ( which often has to be done to adjoin codification ) . update to dry wall is typically done in one of two ways :
6. Building a modern home with lath and plaster walls is possible but pricey.
If you ’re build up new construction , you could savour the beauty of adhesive plaster wall without theproblems that amount with old homes . It ’s a pricy proposition , however : Be inclined to devote as much as $ 10 or more per square foot to have poultice professionally installed . Compare that to the cost of professionally installed wallboard , which average out $ 1 to $ 3 per square foot .
7. Lath and plaster walls tend to be more environmentally friendly than drywall.
While there are many ways to compare the environmental impact of wallboard vs. poultice walls , lath and plaster of Paris can be more environmentally friendly over the life of the construction product . First off , if well maintained , plaster can last longer than drywall . The Gypsum Association cites a50 - year lifespanfor drywall , whereas cataplasm has been known to last 100 years or longer .
In summation to being more perdurable than drywall , plaster is inhospitable to mould ontogenesis and offer better soundproofing , detachment , and fireproofing , especially if used with metal lath . All of these welfare cut down on the use of other building products and reduce the overall environmental impact of construction , especially of national walls .
fabrication also plays a purpose in the relativeeco - friendliness of the material . The processing of sticking plaster releases carbon dioxide , but the production of gypsum handout sulphur dioxide , nitrous oxide , and carbon monoxide . As well , while wallboard can be recycled , there are n’t many place that will recycle it , and the disposal of drywall in landfills moderate to concern of chemical substance leach and the conception of H sulfide gaseous state . It ’s worth noting , however , that older lath and adhesive plaster wall may have been coated with lead paint or could have asbestos in the mixture , so if you need toremove plaster rampart , it ’s crucial to examine them to find the safest disposal strategy .
