Butyl Pads are generally used for temporary applications or low traffic conditions. These 4" x 4" "sticky" tar pads stay soft and pliable throughout their life thus making it possible to pry a marker off the pad if necessary. The advantage of the pad is quick application, a marker can be applied in just seconds using the peel and sticks pads. To apply markers simply peel the wax paper off one side, press and lay the pad on the road, peel the paper off the top and press the marker into the butyl pad. Sold by the case - 100 per case
