FAQ - Asphalt

HOW LONG MUST THE PROTECTOR DRY BEFORE IT CAN BE EXPOSED TO RAIN?
From 12 to 24 hours, depending on the temperature

DO I REALLY NEED TO APPLY TO COATS OF PROTECTOR?
Yes. For best results, it is important to apply 2 coats. The first coat saturates the pores and the second will give the nice, dark finish.

I'VE REPAIRED THE CRACKS IN MY DRIVEWAY WITH A CRACK FILLER FOR ASPHALT. SHOULD I SEAL IT WITH A PROTECTOR?
Applying a Protector over repaired asphalt will give an even, homogeneous look and hide the repairs.

WHAT ARE THE ADVANTAGES OF A WATER-BASED ACRYLIC SEALANT COMPARED TO A MORE CONVENTIONAL TAR-BASED PRODUCT?
Unlike tar-based sealants, Techniseal® water-based Protectors are basically applied like a simple paint. They are clean, they dry more quickly and tools can be cleaned simply with water and soap. Furthermore, they are microporous, they do not trap moisture, they do not give off unpleasant fumes and are environmentally friendly.

MY ASPHALT HAS ALREADY BEEN SEALED WITH A TAR-BASED PRODUCT. CAN I SEAL OVER IT WITH A TECHNISEAL® WATER-BASED PROTECTOR?
No. It is not recommended to use the Protector for asphalt over a surface previously treated with a tar-based sealant. The Protector will not properly penetrate the asphalt, which will cause adhesion problems.

CAN I APPLY THE PROTECTOR TO NEW ASPHALT?
Yes, however it is recommended to wait 3 to 6 months. HP Epoxy Protector is the ideal product in this case.

WHAT IS THE IDEAL TEMPERATURE FOR APPLYING AN ASPHALT PROTECTOR?
Apply on a nice, moderately warm day (ideally between 15 and 25°C) and when no rain is forecasted for the next 24 hours. Application to excessively hot asphalt will make Protector dry too quickly and will leave overlap marks.

SHOULD I APPLY A FRESH COAT EVERY YEAR?
No. Techniseal® Asphalt Protectors are made to last several years (up to 6 years in the case of epoxy-based HP). They resist very well to wear from traffic and weathering.

WHAT IS THE MOST IMPORTANT THING TO CHECK FOR BEFORE APPLYING THE ASPHALT PROTECTOR?
The weather. It is important to make sure the surface is dry before applying the ProtectoIt is also essential to make sure there is no rain for the next 24 hours following the application. Water or even moisture could react with the Protector and turn the surface white.
