Q: What is the purpose of adding PVA to mortar?

A: Adding PVA (polyvinyl acetate) to mortar improves adhesion, flexibility, and workability. It also enhances resistance to water penetration and reduces cracking in the hardened mortar.

Q: How much PVA should be added to mortar mix?

A: A typical ratio is 1 part PVA to 5 parts water, mixed into the mortar at 5-10% of the cement weight. Exact proportions depend on project requirements and manufacturer guidelines.

Q: Can PVA replace other additives in mortar?

A: While PVA improves adhesion and flexibility, it shouldn’t fully replace specialized additives like plasticizers or waterproofing agents. It’s often used alongside them for enhanced performance.

Q: What factors influence PVA price per kg?

A: PVA price per kg depends on purity, brand, packaging size, and regional market demand. Bulk purchases typically reduce costs, with prices ranging from $2 to $8 per kg globally.

Q: Is PVA in mortar cost-effective for DIY projects?

A: Yes, PVA is affordable and widely available, making it cost-effective for small-scale DIY projects. Its benefits in durability and ease of use often justify the minimal added expense.
