YAPI Gypsum Adhesive has been marketed in two types of gypsum plaster (industrial putty) and gypsum (for bonding gypsum plates to the lower surfaces) according to the adhesion.

• YAPI Gypsum Gypsum Board for mounting gypsum boards and boards covered with polystyrene foam or stone wool insulation on brick, concrete, earthenware, cypress, hoblex and gypsum walls for improved sound and thermal properties. Existing wall or used as plaster and bleach.


• YAPI gypsum plasterboard (dry construction systems) is manufactured in micronized form and with the use of high quality additives with standard formulation, these products are manufactured and tested adequately.


• YAPI plasterboard specially designed to save time and cost due to wall door restructuring and non-structural implementation, along with the use of ALCIBAY plasterboard for long-lasting durability.


• Gypsum wall plaster (industrial putty) due to the use of elastic and reinforcing materials, durable and suitable for bonding gypsum blocks and eliminates unwanted cracks.

Siva's late retardant gypsum product is used for bleaching the building as a primary layer on surfaces such as concrete, cement and mortar, and has many advantages over the traditional bleaching system. Traditional Iranian gypsum is considered to be the universal standard of whitening.

• The quality of gypsum used in this system is very high quality and has cementitious properties such as resistance to moisture and high strength.


• The use of perlite in the spray molding structure has made the gypsum lighter and improved its thermal and insulating properties.


• Due to the lightness and longevity of this type of plaster it is very easy to use than the traditional system and in addition to better final quality, plaster is easier to work with.


• Elimination of common cracks in building whiteness

Plaster-based product that is used indoors and in the design of decoration and repair work. This type of gypsum is known as gypsum used in the manufacture of prefabricated gypsum and is a reinforced type of ordinary gypsum plaster. It is also optimized in terms of retention time and adhesion to the mold.

Sealant powder is used in drywall construction systems as well as sealing surface cracks in building bleaching.

• Additives in this type of plaster while adding to the base strength of the plaster due to the elasticity of its material plays an effective role in the long-term strength of the seams and whitened surfaces.


• This product is ready to mix with water and is easy to use.

It is a reinforced plaster that runs on smooth surfaces. This plaster is used in the finishing of the interior finish of the building and is a good alternative to the usual plaster coatings. This plaster is applied to the surface by a master and used as a finishing layer.

• Satin plaster can also be used for painting finishes on DRY WALL cysts.


• Due to the very thin capability of this plaster, its use is very low and economical.


• After applying on the surface as a finishing surface or painting primer, it reduces paint consumption due to its oiliness and low water absorption.

This spray plaster product is used for bleaching the building as a primary layer on surfaces such as cement and brick, etc. and is sprayed using the machine and has many advantages over the traditional bleaching system.

• The speed of implementation of this method is very high due to the use of the device for splashing compared to the traditional system and is an integral part of building crowding.


• The quality of the gypsum used in this system is very high quality and has good cement properties, including resistance to moisture and high strength.


• The use of perlite in the spray casting structure has made the gypsum lighter and improved its sound and thermal insulation properties.


• Elimination of common cracks in building whiteness
