PlasterGuard (Sealer for Plaster)

Meoded PlasterGuard is a nano-based, water-borne copolymer sealer engineered to waterproof and protect decorative plaster in wet, humid, and high-traffic areas. Self-crosslinking for outstanding adhesion and penetration, it is the go-to waterproofing top coat for Concretta shower walls, backsplashes, and other splash zones. It also boosts durability and stain resistance on busy walls, keeping your finish looking freshly applied for years.

• Waterproofing sealer: ideal for showers, backsplashes, and high-humidity walls in a 3-4 layer application
• Added durability: increases wear resistance and helps prevent staining in high-traffic areas
• Three sheen options: choose Low Gloss, Satin, or Gloss to match your finish
• Multiple sizes: Pint, Quart, and Gallon; a quart covers roughly 62-88 sq ft per three-layer coat
• Roller-friendly: applies easily with a foam roller over fully cured plaster
• Strong adhesion: nano copolymer chemistry bonds tightly to mineral surfaces
• Versatile protection: safeguards Concretta and other Meoded plasters
• Made in the USA: proudly manufactured by Meoded, a leading US decorative finish producer

PlasterGuard locks in your finish and keeps it protected where water and wear are a concern. Pair it with Concretta FS and PlasterSeal Plus for a fully waterproof, long-lasting installation on both vertical walls and horizontal surfaces. Choose your sheen and protect your Concretta finish where water and wear demand it.
