Installation tips
- 1.3-step hole cleaning is critical: blow, brush, blow — skip this and capacity drops 30-50%
- 2.Use a calibrated adhesive dispenser — mix ratio must be correct or epoxy won't cure properly
- 3.Full cure at 70°F is typically 24 hours — check TDS for your specific product
- 4.Engineer specification required for all structural applications
- 5.Diamond core drill produces better hole geometry than hammer drilling for critical applications
