Usage always depends on the type of tent canvas.
- The cotton tent canvas of a trailer tent, for example, will absorb less impregnating agent than the tent canvas of a safari tent.
 - On average you can continue with the usage below.
 - Bottle 1L = 5 to 10 m²
 - It is wise to impregnate canvas, cotton or linen canvas if it is under tension.
 - After all, when the tent is up, you pull the canvas slightly open.
 - Small holes then appear.
 - These holes can cause the tent to allow moisture penetration over time and become damp on the inside.
 - So preferably put up the tent before you start impregnating.
