FAQS on pva ph

Q: What is PVA PH in construction materials?

A: PVA PH refers to the acidity/alkalinity level of Polyvinyl Acetate (PVA) solutions, typically ranging between 4.5-6.5. It affects adhesion and compatibility with other materials like plaster. Proper PH ensures optimal performance in bonding and curing.

Q: How is PVA for plastering applied?

A: PVA for plastering is diluted with water (usually 1:4 ratio) and brushed onto surfaces before plastering. It improves adhesion, reduces porosity, and prevents rapid drying. This ensures a smoother finish and minimizes cracking.

Q: What is the average PVA price per kg?

A: The price of PVA glue varies between $1.50 to $5 per kg, depending on brand, concentration, and region. Bulk purchases or industrial-grade products may offer lower rates. Prices fluctuate with raw material costs.

Q: Does PVA PH affect plaster curing time?

A: Yes, overly acidic or alkaline PVA (outside 4.5-6.5 PH) can alter plaster setting times. Neutral PH balances workability and strength. Always test compatibility with specific plaster mixes beforehand.

Q: What factors influence the cost of PVA?

A: Key factors include polymer purity, additives (e.g., water resistance), packaging size, and supplier markup. Construction-grade PVA is cheaper than specialized variants. Global resin prices also drive long-term cost changes.

Q: Can PVA for plastering replace primer?

A: Diluted PVA is often used as a budget-friendly primer for plastering on porous surfaces. However, dedicated primers may offer better moisture resistance. Avoid using PVA in high-humidity areas without additives.

Q: Why does PVA price per kg vary across brands?

A: Brand reputation, formulation patents, and concentration (e.g., 10% vs. 20% PVA content) cause price differences. Premium brands may include stabilizers or antifreeze agents, increasing costs. Always compare dilution ratios for value.
