Frequently Asked Questions
Required Putty (kg) = Wall Area × Consumption Rate ÷ 10. For example, 1,200 sq.ft at 1.5 kg per 10 sq.ft needs 1,200 × 1.5 ÷ 10 = 180 kg.
It depends on the putty brand, the number of coats, and how uneven the wall surface is. Always check your specific product's packaging for its recommended consumption rate.
