There is no simple answer. We have customers using our markers on utility patches on roads in Virginia, on curb faces in Minnesota, and sidewalks in Florida. Because of the wide variety of applications and weather conditions, there is no simple answer. UV degradation is the key factor. We have independent test data as well as our own available for your review.
Abrasion is the other factor that determines longevity. Vehicular/pedestrian traffic, street sweepers, salt, chemical exposure and a variety of environmental elements can have an effect.
Our marker offers both increased UV protection and abrasion resistance.
They require a hammer and chisel for removal. When fully cured the adhesive forms a permanent bond between the marker and application surface. We have test samples in place with no loss of adhesion after more than 15 years. We also have test samples on roadways, purposely placed in the tire path, that are still in place after more than 8 years.
By comparison, others offer:
- Thermal-Plastic tape which requires a propane torch for installation. This system is not exactly “user-friendly” and requires great care in application. Too little heat and it won’t stick. Too much heat and you end up with a graphic that is an illegible blob.
- Pressure-sensitive lane tape which requires a surface primer and a tamping machine. Without appropriate pressure, it will lose adhesion and separate from the application surface in a short period of time.
- Aluminum or Ceramic markers which offer no proven compatible adhesive (customer has to provide) or some aluminum and brass “systems” that require diamond-tipped drill bits for making holes and hardware for mounting.
The Drain Marker adhesive comes in a 5-ounce squeeze tube. Our adhesives have been tested and used under a wide variety of conditions since 1983 and offer the perfect combination of long-term durability and ease of use.
What about street sweepers, snowplows, and vandalism?
Our customers experience little loss from these hazards. Our tests and testimonials from our customers indicate little to no damage from street sweepers. A snowplow would be capable of scraping off a Drain Marker. However, the Drain Marker has been used extensively in snow belt areas and our customers report very little to no actual loss. A determined vandal can remove the Drain Marker. Although in over 19 years, we’ve received very few reports of actual occurrences exceeding 1-2%. The benefits of permanent marking with the Drain Marker far outweigh the risk of occasional loss or damage to the marker due to any of the above factors.
Is adhesive included?
Yes, each kit comes with 25 markers AND the adhesive.
How long does the adhesive take to cure?
The adhesive will skin over in 1-hour, become hard to the touch in 4 hours, and achieve a full cure in 18 hours.
