Tile adhesives excel in bonding ceramic and porcelain tiles in humid Indian settings like bathrooms, offering polymer-modified flexibility to resist minor movements and splashes. Apply them over a dedicated waterproof membrane for layered protection, mixing to a lump-free paste and back-buttering tiles for full 3-5 kg/m² coverage without voids. Limit bed thickness to 10mm, prime substrates first, and allow 24-hour curing before grouting to prevent cracks and ensure 1 N/mm² shear strength.
