Should I Buy a 25 kg or 30 kg Bag?

For Gach Sahar finishing gypsum and super micronized Maral and Jabal, the technical specifications for both the 25 kg and 30 kg versions are the same on the product page. The main difference is the bag weight and price. For a fair comparison, divide the price of each bag by its weight to find the price per kilogram. The lighter bag makes manual handling easier in the workshop, while the heavier bag reduces the number of bags needed.

Conclusion

If you only want one number: most of Gach Sahar's construction gypsum bags are 25 kg, and there are several products available in the 30 kg version as well.
