The wholesale purchase of porcelain glue and slabs in Tehran market is directly related to cost control and eliminating the risk of heavy stones falling in high projects. Due to the near zero porosity (below 0.5%), porcelain tiles do not form a molecular bond with traditional mortar and are restrained only by cement-based polymer adhesives with C2TE S1 and S2 standards. By eliminating intermediaries, Zafari glue group provides direct supply of high tonnage from the factory production line to the construction projects of Tehran province, guaranteeing the authenticity and production date of the day.
In the implementation of large size ceramics and porcelain slabs in modern structures of the capital, choosing the wrong glue is equal to heavy financial damage and life risk. The heaviness of each slab sheet and the day and night temperature changes in Tehran require a material that maintains the necessary tensile and polymer flexibility over time.
The hidden challenges of supplying slab and porcelain glue in Tehran materials market
Active construction projects in areas such as District 22, Elahia or Saadat Abad often face delays due to bad character of bankers and lack of continuous supply of a certain part of glue. In practice, it has been observed that changing the brand of glue in the middle of a project causes a difference in the thickness of the substrate and even inconsistency in the drying time of the glue under the tiles.
On the other hand, Tehran's materials market is facing constant price fluctuations in the resins and imported powdered polymers sector. Many intermediate distributors supply cargo lying in substandard warehouses with dated packaging or lumpy adhesives that have lost their original adhesive properties. Buying directly from centers that have basic warehouses and high stock turnover reduces this operational risk to zero.
Technical standards of slab and porcelain adhesive from a laboratory point of view
For flawless installation of large size tiles such as 120 x 240 or 160 x 320 cm, the material used must have passed at least national and European standard tensile tests.
Slip resistance and open time (characteristics T and E)
In high walls or the front of lobbies, the glue should have vertical anti-slip properties (Slip Resistance or T abbreviation) so that the stone does not fall down during the initial setting. Also, the extended open time (E) allows the operator to place and level the tile at least 30 minutes after performing the comb on the surface without closing the adhesive layer.
Flexibility and absorption of structural stresses (category S1 and S2)
Advantages of bulk and direct purchase from Zafari glue warehouse
Bulk purchase of building materials should ensure the security of the supply chain. Supplying materials at once creates decisive advantages for contractors:
- Reduction of 15 to 25% purchase cost: Eliminate local dealers and send full pallets directly from the production line or central warehouse to the workshop.
- Ensure homogeneity of load formulation: All the bags sent for your project are loaded from a specific production batch so that there is no difference in grip, color or concentration.
- Immediate delivery to all parts of the capital and Suburbs: Send tonnage and materials in the shortest time to the construction workshops of Tehran, Karaj, Pardis and Islamshahr without delay and delay of the project.
- Technical consultation before the order: Evaluation of the substructure material (concrete, plaster, light block or old tile) to suggest the best type of glue according to the budget and technical needs.
The key points of applying powder glue to prevent porcelain tabulation
According to our technical investigations in numerous construction projects, more than half of the failures of porcelain installation are caused by incorrect gluing method and have nothing to do with the quality of the tile itself:
Double buttering technique (Back Buttering)
For porcelain with dimensions higher than 60 x 60 cm, it is not enough to apply glue only on the floor or the body of the wall. The back of the tile should also be coated with a thin layer of adhesive and then placed on the grooved surface so that the adhesive coverage under the stone reaches more than 95% and no air bubbles remain.
Paying attention to the date of use and storage conditions of the pallets
Powder and polymer base glue bags should not be stored on wet soil or exposed to rain. Using healthy wooden pallets and not stacking more than 8 bags on top of each other prevents the polymers from clumping. Zafari glue stores all products in a dry and ventilated environment and delivers them with a guarantee of physical health.
