A guide to ordering from the factory

Prepare your product choice, bag quantity, destination city and unloading requirements. Sales will confirm current pricing, transport costs and available delivery arrangements. A quote request is not a completed purchase.

Useful details

These guides address practical site decisions: selecting materials, estimating quantities, storage and ordering. The product instructions and responsible installer’s assessment govern the final application.

Practical site questions

How many square metres does a bag of gypsum cover?

Our undercoat benchmark is one 33 kg bag per 1.3 m² at 2 cm. Enter the actual wall and ceiling area, thickness and bag weight. Confirm the final quantity with your plasterer, allowing for surface unevenness and application.

Mianeh black gypsum: application and pricing

Black/undercoat gypsum and ready-mixed gypsum-soil prepare and level walls and ceilings. This base coat is generally thicker than the white finishing coat used to create a smooth appearance before paint preparation. Specify the exact product when ordering.

Micronized gypsum and undercoat: what is different?

Micronized describes powder fineness and processing. Undercoat describes a role in the first plaster layer. These terms describe different characteristics, and neither replaces a product data sheet.

Plaster setting versus drying: when is it ready?

Setting and drying are different processes. A firm surface does not mean all moisture has left. Decide when to apply the next layer using the product instructions and actual site conditions.
