When using injection resins it is essential to follow the correct hole cleaning procedure :
1. Drill hole in the substrate to the required embedment depth using the appropriate size drill bit.
2. A blow out pump must be used for blowing out drilled holes up to diameters < 24mm and embedment depths up to 10x drilled hole diameters. Blow out at least 4 times from the back of the drilled hole, using an extension if needed.
3. Brush 4 times with the specified brush size by inserting the steel brush to the back of the hole (if needed with an extension) in a twisting motion and remove the debris.
4. Blow out again with pump at least 4 times.
