Choosing the right gypsum for painting is a crucial decision in construction and renovation. Semnan gypsum has always been popular due to its high quality and unique properties. But the question is, is white gypsum better for painting, or base gypsum? In this article, we will examine this issue in detail and help you choose the best option by providing comprehensive information.

White Gypsum or Base Gypsum: Which is Better for Painting?

In short, white gypsum is a better option for priming for painting due to its softer texture, smoother surface, and lighter color. However, using base gypsum as the first layer can help increase the lifespan and overall quality of the painting due to its greater strength and adhesion. The final choice depends on the type of project, budget, and your preference.

Semnan Gypsum: A Smart Choice

Semnan gypsum is one of the best options for use in construction, especially for preparing surfaces for painting, due to its high purity, excellent whiteness, and suitable particle size. The rich gypsum mines in Semnan have made this region the center of quality gypsum production in Iran. Gypsum produced in this region has many fans at home and abroad due to its unique properties. Gach Sahar Semnan gypsum uses the best mines and the latest technologies to produce quality gypsum that meets global standards.

White Gypsum: Delicacy and Beauty for Painting

White gypsum, also known as finishing gypsum, creates a smooth, uniform, and white surface due to its very fine particle size and high purity. These features make white gypsum an ideal option for the final layer before painting. The smooth and even surface of white gypsum allows the paint to spread evenly on the surface, resulting in a beautiful and flawless appearance.

Advantages of White Gypsum for Painting:

* Smooth and Uniform Surface: White gypsum creates a smooth surface without imperfections, which is very suitable for painting.
* Light Color: The white color of white gypsum allows the original color to show well and does not change the color.
* Soft Texture: The soft texture of white gypsum allows the paint to spread easily on the surface and creates better coverage.
* Suitable Setting Time: The suitable setting time of white gypsum gives you enough time to work with it.

Disadvantages of White Gypsum for Painting:

* Lower Resistance: White gypsum has less resistance than base gypsum and may be more vulnerable to impact and scratches.
* Higher Price: The price of white gypsum is usually higher than base gypsum.

Base Gypsum: High Strength and Adhesion

Base gypsum, also known as gypsum خاک (gypsum soil), is used for the initial layers of plastering due to its coarser particle size and higher strength. Base gypsum adheres well to the underlying surface and creates a strong layer that can protect the subsequent layers. However, the surface of the base gypsum is usually rough and uneven and is not suitable for direct painting.

Advantages of Base Gypsum for Painting:

* High Strength: Base gypsum has high strength and can resist impact and scratches.
* Strong Adhesion: Base gypsum adheres well to the underlying surface and creates a strong layer.
* Reasonable Price: The price of base gypsum is usually lower than white gypsum.

Disadvantages of Base Gypsum for Painting:

* Rough and Uneven Surface: The surface of the base gypsum is rough and uneven and is not suitable for direct painting.
* Dark Color: The color of base gypsum is usually darker than white gypsum and may change the original color.

Comparison of White Gypsum and Base Gypsum for Painting

| Feature | White Gypsum | Base Gypsum |
| ------------- | ---------------------------------------------------------------------------- | ----------------------------------------------------------------------------- |
| Surface | Smooth and uniform | Rough and uneven |
| Color | Light (white) | Dark |
| Particle Size | Fine | Coarse |
| Strength | Lower | Higher |
| Adhesion | Lower | Higher |
| Price | Higher | Lower |
| Application | Final layer before painting, creating a smooth and beautiful surface | Initial layer of plastering, creating a strong and adhesive surface |

Solutions for Using Base Gypsum for Painting

If you decide to use base gypsum for the initial layers of plastering due to its strength and economic advantages, you can prepare the surface for painting by following these tips:

Use of Intermediate Layer: After applying the base gypsum, apply a thin layer of intermediate gypsum (such as polymer gypsum) to cover the surface irregularities.

Use of Putty: After the intermediate layer dries, use putty to fill the pores and create a smooth surface. Gach Sahar Semnan putty powder, with high quality and reasonable price, can be a good choice for this step.

Sanding: After the putty dries, smooth the surface with fine sandpaper.

Use of Primer: Before painting, use a primer to increase the adhesion of the paint to the surface and prevent the gypsum from absorbing the paint.
