What are the minimum inside corner radius requirements for quartz cutouts, and when is reinforcement required around sinks and cooktops?
Minimum radius and reinforcement practices should be followed when fabricating sink and cooktop openings in engineered quartz.
Cutouts, Radius & Reinforcement Guidelines:
- Minimum inside corner radius for cutouts: 3/8″ (10 mm)
- Recommended inside corner radius: 1/2″ (12 mm)
- Avoid sharp internal corners in sink and cooktop openings
- Reinforcement, such as rodding or approved underlayment is recommended around sinks and cooktops, particularly with thinner materials
