A Comprehensive Guide to Using Gypsum Plaster

Gypsum is a naturally occurring mineral, mined for its soft, sulphate composition. Once refined into a fine powder, it is transformed into gypsum plaster, a material known for its smooth finish and ease of use. Gypsum plaster, such as RhinoLite®, is primarily used for internal applications on various surfaces, offering durability and flexibility. One of the trusted products in this category is the Gyproc Plasters range, which is designed to meet the needs of professionals and DIYers alike.

• RhinoLite® Skimming Plaster: Gyproc RhinoLite® Multipurpose, Natural Plus and CreteStone are perfect for creating a smooth finish on walls and ceilings.

• Moulding Plaster: RhinoMould® is used for decorative mouldings and detailed designs.

Gypsum plaster is best suited for various internal surfaces, provided they are properly prepared. While the material is highly versatile, it’s crucial to apply it to the correct surfaces for optimal results.

Bonus Tip: Avoid applying gypsum plaster to fibre cement boards, timber and timber boards, EPS (expanded polyester), tiles and bitumen as they may not allow proper adhesion.

Proper surface preparation is essential to achieving a flawless, long-lasting finish with RhinoLite® gypsum plaster. The following three steps will help ensure that the surface is ready for plastering and that the application adheres properly.

Step 1:

Clean the Surface: Ensure that the surface is free of dust, dirt, grease, and oil.

Step 2:

Repair Surface Flaws: Address any large cracks or imperfections before applying plaster. A smooth, even surface is essential for a professional finish.

Step 3: 

Prime the Surface: Proper priming is crucial for good adhesion. Use an appropriate plaster primer to ensure that the surface is prepared for the gypsum plaster application.

Applying gypsum plaster can be a crucial step in achieving a smooth and aesthetically pleasing finish on walls and ceilings.
