Bore-Gel contains premixed bentonite, polymer, and soda ash. Follow guidelines below to ensure proper

• If chemicals are added in the wrong order, they will not mix properly and will form clumps.
• If tank contains bentonite/polymer mix and more drilling fluid is needed, completely empty tank and
start with fresh water before mixing another batch.
