Thinset Buying Guide
This guide helps you turn your thinset calculator result into a cleaner purchase plan. Use it when you want fewer return trips, better waste assumptions, and a more realistic cart.
Step 1: Know your trowel notch size
Large 12x24 tiles require a deep 1/2-inch notched trowel, which consumes massive amounts of thinset. Small subway tiles use a 3/16-inch trowel and stretch the bag much further.
Step 2: Avoid pre-mixed buckets for floors
Pre-mixed 'mastic' in a bucket relies on air to dry. If you use it under large floor tiles, the center will never cure. Always buy dry bags of Portland cement thinset for floors.
Step 3: Check your waterproofing membrane
Systems like Schluter Kerdi often require unmodified thinset so it can cure properly between two impervious layers. Read the membrane manufacturer's instructions carefully.
