Some boring history, gypsum and fiberboard sheathing can and has been used for a solid backing for stucco around the 1950s some say fiberboard has been around for hundreds of years while gypsum board, sheetrock or drywall (all name means the exact same thing for the gypsum products) has been around from around the 1950s. Both were better than just studs when applying stucco to a home as they had insulation and sound proofing abilities.
However and here’s the part old Kirk’s familiar with, both are a real drag to tie into if either of these boards gets wet, they become really soft and most time, for say repairs of water damage or window and door replacement, it’s a real drag to get a new water barrier under or over it.
Most times it’s just as difficult as a stud wall with stucco over it.
Gypsum sheathing boards are usually white in appearance in the center, with many different paper coatings.
Both boards were used years ago generally for exterior purposes while gypsum is used for interior purposes as it was sold with a water-resistant paper covering on its face. It was sometimes attached to studs to make a solid backing for stucco or other finishes for brick veneer, it is outdated for a reason!
Fiberboard is usually made from recycled newspaper, wooden fibers, and other products that are glued together. fiberboard can has has been be used for sheathing, as it also provides sufficient backing for stucco at one point in time. early 1900 to 1950 as a rule, of course if a fella today finds it in his garage in 2015 he might still use it. Stranger things have happened!
FYI, anyone interested in the material we used tin this video that would adhere and stick a solid inch at a time, it was Eisenwall cement plaster made by Rapid Set.
This cement plaster can be applied up to 6 inches thick back to back same day.
Eisenwall is a premium hydraulic cement for exterior plastering, one coat stucco and wall repairs, this material requires a citification for good reason, (or used to) it really requires a lot of time in to understand how to mix and apply as it sets REALLY FAST (in 15 minutes to a half hour) unless you add retardants, and is incredibly strong, so strong that if you don’t apply if just right it’s not coming off, even with a sludge hammer.
Rapid set also sells a simullar cement plaster at all the Home Depot’s and Lowes, hardware store, just not this brand, the rapid set you DIY’ers purchase at these hardware store’s already comes with the sand, you just add water. Much more user friendly.
This Eisenwall, we must also add the sand, plus the water, it’s sold at Westside Building Materials and many of the professional plastering material yards, not sure if a citification is still required.
