H&C^® HB-150/HB-100 Water Repellents
H&C^® HB-150/HB-100 Water Repellents are mineral spirits-based water repellents designed to provide a long-lasting, breathable barrier against water, airborne dust, dirt, salt, acid rain, efflorescence, alkali and freeze/thaw damage. Both products provide an invisible, no-film finish and can be stained or painted. HB-150 is 15% siloxane solution and HB-100 is 10% siloxane solution. Both products are excellent water repellents for driveways.

Important Things to Keep in Mind

Weather Conditions

• Air and surface temperature should be between 50º and 90ºF for 24 hours following application. This will ensure proper product penetration.
• You must protect the coating from rain for 4 to 5 hours to allow the water repellent to become effective.

• No etching is required when using on a textured or broom finish.
• Before applying your coating, make sure you have followed the proper surface preparation methods for the surface you are coating.
• For horizontal applications, after surface prep, sweep the surface with a stiff broom to remove any remaining residue.
• Two coats are required if you are using this product by itself.

• Cleanup is easy - simply use mineral spirits after your project is complete.

Application Methods

• If your surface has corners or edges, coat those with your brush first to assure complete coverage of the water repellent.
• Using your low pressure airless sprayer, conventional sprayer or power roller, apply the water repellent.
• For best results, use a low pressure sprayer so the solution is applied in the form of droplets rather than a mist.
• Vertical surfaces must be "flooded," allowing the material to run down 8 to 10 inches. Always work from the bottom up.
• Horizontal surfaces can be applied by the "flood" method or with a conventional roller or brush as long as enough material is used so it can stand for a few seconds before completely penetrating.
• Let your first coat dry 24 hours before applying your second coat.

Please note: When dry, treated surfaces appear identical to untreated surfaces so it's difficult to determine whether or not you have already treated an area. Be sure, when taking a break, to stop applying either on a corner or any other obvious marker so you can re-start the application exactly where you ended it.
