Plaster and Its Characteristics
Plaster’s like the unsung hero of walls, holding everything together and looking good while doing it. Understanding its different types and properties helps you know if Polyfilla can play nice with it.
Types of Plaster
You’ll find several types of plaster, each with its quirky charm.
- Gypsum Plaster: This one’s a favorite for its quick-setting nature. It dries faster than you can say “DIY disaster,” usually within 30 minutes.
- Lime Plaster: Known as the granddaddy of plasters, limestone, and water mix to create a breathable finish. This beauty can last for decades if treated right, becoming more durable with age.
- Cement Plaster: This tough guy holds up against the elements. Ideal for external walls, it has a long lifespan and is hard as nails, though it takes a bit longer to set.
Properties of Plaster
Plaster isn’t just a pretty face; it comes with a bag of tricks.
- Durability: It can withstand a lot of wear, but it’s not immortal. On average, plaster can last over 50 years, making it a solid investment for your walls.
- Porosity: It breathes! This means it can absorb moisture, crucial for preventing mold. Just don’t drown it; think of it like a light drizzle, not a flash flood.
- Adhesion: Plaster sticks to surfaces like your favorite cat to the sunniest spot in the house. Its bonding abilities make it perfect for additional layers, like Polyfilla, as long as you’ve got a clean surface.
By knowing these characteristics, you can decide whether Polyfilla will fit into your plaster’s life story without causing a drama.

A little prep goes a long way to make your repairs last.
