FAQS on pva for plastering walls
Q: What is PVA used for when plastering walls?
A: PVA (Polyvinyl Acetate) acts as a bonding agent and primer. It improves adhesion between plaster and walls while reducing wall absorbency to prevent rapid drying of plaster.
Q: Should I apply PVA to walls before plastering?
A: Yes, applying diluted PVA (1:4 ratio with water) creates a tacky surface. This helps fresh plaster adhere better and minimizes cracking as it cures.
Q: Can PVA be used for walls before tiling?
A: While PVA can create a temporary bond, it's not recommended for tiling. Use cement-based primers instead, as PVA degrades when exposed to moisture over time.
Q: How long does PVA take to dry before plastering?
A: Typically 1-2 hours for touch-dryness. Wait until it becomes tacky but not fully cured - usually 30-60 minutes after application - for optimal plaster adhesion.
Q: Is PVA a substitute for proper wall preparation before plastering?
A: No. PVA enhances bonding but doesn't replace essential preparation. Always clean surfaces, repair cracks, and remove loose material before applying PVA and plaster.
