How much joint grout is needed per square meter?


In general, the amount of joined grunt depends on factors such as tile dimensions, grout joint width, tile thickness and the area of the work.

It is calculated through the following equation:

X= (A+B)*C*D*1.56                           K=X*work area


A: Tile length

B: Tile width

C: Grunt joint width

D: Tile thickness

K: Kg of powder required


How to use and how much is the consumption of tile adhesive?


Sahand Chemical powder tile adhesive is in a package of 20kg, which covers 5 square meters of surface.

In general, 4kg of tile adhesive powder is required per square meter of smooth surface free of worms and rot. To use powder tile adhesive, first pour 5 liters of water in a clean container and add tile adhesive powder into it simultaneously. continue stirring the mixture, until a homogeneous mixture is obtained. then let the mixture rest for 5 minutes and continue stirring again for two minutes. by using a squared -notched trowel and creating parallel grooves, we apply the adhesive tile on the desired surface and install the tile in a maximum of 20 minutes.

Note: after mixing the powder adhesive with water, apply the mortar for a maximum of one hour. 


Does hydrophobic joint grount powder have waterproof sealing properties?


Sahand Chemical hydrophobic joint grount powder has hydrophobicity and reduced water adsorption.

This product consists of hydrophobic additives that reduce the penetration of contaminants and water into the mortar. To increase the adhesion and compressive strength, as well as increasing the hydrophobicity and reducing water adsorption, this product should be mixed with Sahand Chemical latex (or mortar strengthening) resin.


Is it possible to mix powdered tile adhesive with cement and powdered store?


Sahand Chemical powdered tile adhesives are based on cement, mineral, polymers and special additives. The mixing percentage of these materials is proportional to Sahand Chemical formulation and is measures.

If additional materials such as stone powder and white cement are added to this mixture, it will change and disrupt the proportion of materials and additives, and will change the performance of these materials, reduce adhesion, strength and generally the function of tile adhesive.

For this reason, it is strongly recommended to use Sahand Chemical powder tile adhesives without any additives.


In what cases two-component waterproof is used?


Sahand Chemical two-component waterproof has 2 parts. part A is powder and part B is liquid (resin) this product is suitable for sealing roofs, swimming pools, toilets, baths, water fountains, water-treatment plants and tanks under positive hydrostatic pressure. 


How many days after the implementation of the two – component waterproof the desired location can be utilized?


Sahand Chemical two – component waterproof can be easily applied with a brush, spatula and trowel. Let it rest for 7 days and after that, the user space could be exploited.


Does concrete bonding adhesive has sealing properties?


Sahand Chemical polymeric concrete bonding adhesive is based on latex and is used to increase the adhesion of concrete, reduce the permeability and sealing of concrete. This product can be used as a sealant for cracks and joints of concrete surfaces. It can also be used to block water inlets on roofs and terraces or any section that is exposed to water.



How much concrete bonding adhesive should be to concrete and required to seal it?


The amount of concrete bonding adhesive depends on the use of the place, its usage and surface properties of the area. In general, in order to seal and increase the compressive and tensile strength to frost and prevent cracking and flattening of the concrete, adding 5 to 20% of the weight of cement in concrete of Sahand Chemical polymeric concrete bonding adhesive is suggested.



What is the difference between powder and dough tile adhesive?


Dispersion tile adhesive has a shorter shelf life than powder type due to the activation of its chemical components.

Also, for each square meter of surface and installing one square meter of tile with dispersion adhesive, usually between 5 to 7 kg of adhesive is needed. But for the same tile size, 3 to 5 kg of powder adhesive is enough

Powder adhesive is cheaper than similar quality dispersion tile adhesive.

Due to the presence of polymers, powder adhesives become resistant to moisture after drying.

But dispersion adhesives do not have this property in the presence of moisture, and after a while, it creates an unpleasant odor in the user space
