Plastrum Lime Plaster Basecoat

Our premium natural lime plaster basecoat — designed to go directly over Plastrum Lime Primer and under Plastrum Lime Plaster Finish. It delivers a strong, flexible, breathable base that works beautifully over modern substrates: drywall, blueboard, cement board, painted surfaces, and even foam board. Perfect for both interior and exterior applications, Plastrum Lime Plaster Basecoat finally brings 100% natural lime performance to today’s building materials. Why It Performs Made with the same high-pH, high-calcium, carbonating aged lime putty that Lancaster Lime Works is famous for, this basecoat includes our proprietary earth-based binder for superior adhesion and workability over non-traditional surfaces. The result is a durable, crack-resistant layer that breathes naturally while bonding reliably to modern walls. Installation Hints: Apply directly over the Plastrum Lime Primer.  If needed and after a coat of Plastrum Lime Primer, the Plastrum Lime Plaster Basecoat can be used to flatten uneven surfaces.  Correct any unevenness of the wall before applying the last coat. Cover and mask surfaces. Wear proper gloves, safety glasses and any other personal protective equipment to avoid contact. Pour off the water on top, mix and knock-up the plaster well before using.  Mixing time will vary depending on the workability desired for the project.  Add water to achieve certain finishes and workability.  Apply to dry primed impervious surfaces. If applying to pervious surfaces (ie.cinderblock) slightly dampened before installation. Apply using a stainless steel stucco trowel. Basecoat does not need to be covered with the finish coat, and can achieve many different types of finishes.  Practice mockups before tackling the entire project.  The practice mockups will ensure the installer has experience for the type of finish desired.  Slow or stop the setting of Plastrum Lime Plaster Basecoat by misting the wall. Work to the desired finish.  Important Notes Cover and protect surrounding surfaces. Wear gloves, safety glasses, and appropriate PPE. Set time varies with temperature and humidity — cooler, humid conditions will extend working time. Ready to bring authentic lime plaster performance to your next project?
