Tile Adhesive Calculator

How to use it

1. Determine consumption by method: double coating = 8 kg/m²
2. Calculate total: 50m² x 8 kg/m² = 400 kg
3. Calculate bags: 400 kg ÷ 25 kg/bag = 16 bags
4. For double coating: Apply adhesive to substrate AND to tile back

Common mistakes

• ⚠️ Not using double coating for tiles larger than 30x30cm
• ⚠️ Using same adhesive indoors and outdoors (must be flexible outdoors)
• ⚠️ Not respecting adhesive open time (dries before placing tile)

Worked example

Calculate adhesive for 50m2 of tiles.

For {area} m² with {tipo_installation}: {total_kg} kg of adhesive ({sacos_25kg} bags of 25kg). Consumption: {kg_m2} kg/m².
