Synthetic Ice and Water
Works Better Long-Term
The difference between good performing and poor performing ice and water underlayment is its ability to stick. Not only stick but stick in conditions that are usually less than desirable - after all weather is not predictably perfect and job site are not 100% clean. This sticking is critical to it being waterproof. (Read the "Stick Later Myth" below)
The other differences are the performance characteristic such as UV degradation, tear strength and blow off resistence. These are properties that can not be met easily with asphalt based ice and water underlayments, only designed synthetics can meet the challenge.
"It is not stick right now but when the sun warms it up it will bond." This stick later myth has really really hurt the construction industry. The fact is that really not true.
"If it does not stick it does not seal." If a peel and stick underlayment does not adhere and create an water/air tight bond, it will never be able to keep moisture and air from entering in.
When the release paper is pulled off the asphalt based adhesive, the oxidation process begins. When oxidation starts asphalt starts to lose its flexibility and begins to harden and become brittle. Once this oxidation process begins, bonding becomes more difficult and eventually impossible.
Won't the sun heat up the asphalt and make it stick? If it is already oxidized it is not likely in field conditions. . If the asphalt is not fully oxidized the temperature to get regular asphalt to its soften point is 204ºF - 215ºF. Modified or rubberized asphalt will begin to soften at 185ºF - 210ºF. Does a roof or wall get that hot on a summer day? Most studies show the highest roof temperatures (black shingles) in the south is 180º F, that is on the hottest days. In the central and northern climates the temperatures are less. Lighter colored materials will have a lower temperature by 7ºF - 15ºF.
The bottom line is that this myth about adhesives sticking later has caused brought much confusion and liability to the construction industry. The alternative is to have something that will stick right away, in any weather. The answer is clear Micro-Grab™ adhesive technology by Weather-Bloc. No guessing, no hoping, Micro-Grab adheres every time.
