Plaster and putty are two essential materials for preparing walls and ceilings. Although similar, they serve different purposes. Mistakes in choosing between them can lead to cracks, unevenness, and poor finishes. Let’s compare the most popular types of plaster and putty, their advantages, disadvantages, and best uses.
Why they are needed
Plaster levels large irregularities and forms the base.
Putty provides the final smooth layer before painting or wallpapering.
Popular plasters
– Cement plaster: strong, moisture-resistant, but slow drying.
– Gypsum plaster: smooth, easy to apply, but not moisture-resistant.
– Lime plaster: eco-friendly, mold-resistant, less durable.
– Polymer plaster: elastic, decorative, but more expensive.
Popular putties
– Base putty: for rough leveling.
– Finish putty: for smooth finish.
– Universal putty: versatile but compromises quality.
– Polymer putty: plastic, minimal shrinkage, premium quality.
Comparison
Plaster handles thick layers (5 mm – several cm), while putty is thin (0.5–5 mm). Cement plasters are moisture-proof, gypsum plasters are not. Putty provides smoothness but less strength.
Common mistakes
– Using gypsum plaster in wet rooms;
– Applying finish putty on uneven walls;
– No primer before application;
– Relying only on universal putty.
Tips
– Use cement mixes in wet zones;
– Gypsum for living rooms;
– Finish putty is essential before painting;
– Buy certified materials;
– Test adhesion before full application.
Conclusion
Plaster builds the base, putty creates the perfect finish. Correct choice depends on room conditions and final design goals. Shugan Home helps clients choose the right materials for durable and beautiful interiors.
