1) When can I apply it?
Our products cure primarily through evaporation. The ideal conditions would be warm bright sunny days, about seventy degrees is best. In marginal conditions, it is best to use Elasto-Barrier. It is colored and draws heat from the sun and will cure much faster, even at temperatures as low as forty degrees.

2) How does it stop leaks?
If you apply coating by pouring it out and pushing the puddle, when it comes to a crack, hole, or seam, it will flow into it and when it cures becomes a non-penetrable seal. Of course, larger openings require additional coats but not to the extent of most of our competitors products which tend to be much thinner and runnier. Ames products are purposely made thicker to reduce the amount of labor required to reach your goal.

3) My customer wants an almond colored Coating
Many applications, especially RV’s, involve light colors and the customer’s goal is to not have a stark white on the roof. This is easily accomplished in your paint department. Simply have the customer pick out an exterior (more colorfast than interior) color chip that calls for a white or pastel tint base and use this exact formula to tint either Snow Seal® or Iron Coat. The color will be very close. As Elasto-Barrier is colored, do not attempt to tint it.

4) How much will I need?
Coverage, particularly on the first coat is determined by how rough or smooth the existing surface is. Most applications on a smooth surface will be about one-gallon for every 100 square feet (a 10 foot by 10 foot square equals 100 square feet). This is true for metal, smooth tar (asphalt), rubber membranes, and other smooth surfaces. A granulated surface, such as rolled roofing (approximately three feet wide is standard, but half-lap exists and is about eighteen inches wide) will use about one-gallon for every 50 square feet (5 foot by 10 foot). Subsequent coats will use a standard one-gallon per 100 square feet.

5) How is it applied?
Easily with a brush (small areas or edges), a paint roller (larger areas), and for commercial applications, it may be sprayed with a commercial coatings sprayer (not a paint sprayer). We have received several reports of individuals applying with their bare hands but this is not recommended. Though for most individuals it is not toxic and causes no adverse reaction, it’s really hard to clean your hands after an hour or so.

6) How long does it last?
Service life is predicated on exposure and the thickness of the coating. On the equator it is not likely to last as long as it would in Minneapolis, MN due to the difference in UV exposure and the average daily temperature.

Additionally, the thicker the coating, the tougher it will be and the longer it will last. As a rough rule of thumb, one to two years for one coat, and then add two to three years for each additional coat. It would not be at all unusual to expect between five and ten years from a three-coat application.

7) Which product(s) are better for me?
First, establish the customer’s goal (s). If reflectivity and cooler roof temperatures are the goal, then use Maximum-Stretch, Snow Seal or Iron Coat (for metal roofs). If the customer has serious leaks he or she is recommended to pre-seal with the Elasto-Barrier, using seam tape or fabric as necessary, and then use Maximum-Stretch, Snow Seal® or Iron Coat. Sealing leaks is important. If in doubt about a specific application, please call us first, 1-888-345-0809. The product label is a good source for this type of information.

8) What types of roofs can be coated?
With few exceptions, all roofs. But, some work better than others. Coating is very efficient for metal roofs (campers, RVs, mobile homes, travel trailers, barns, pole buildings, corrugated, double vee, and on both galvanized and aluminum. You can even coat over rusty metal and stop the rust if you use Elasto-Barrier first. Coating is very good on Bur’s (built up roofs), rolled roofing, half-lap, and granulated sheet goods. Poor applications (not recommended) would be for surfaces that do not offer a good bond, such as brand new (un-weathered) metal, Silicone roofing, silicone caulk, waxy surfaces (used as a release agent for some sheet goods), and un-weathered EPDM (a special type of sheet goods that uses silicone as a release agent during its manufacturing process).

For those of you who are completely baffled at this point, do a simple test. Paint generously a small area (say four or five inches square) with common latex house paint. Allow to dry. Attempt to remove the test spot with your fingernails. If you can dig it up one fingernail full at a time, the roof is a good candidate for coating. If the test spot comes up in a sheet, adhesion is lacking and you may run a risk coating it.

9) What is the most common “oops” to occur in an application?
Using the correct amount of product to do the job. Not only not enough, but also using too much occurs. Do your very best to apply at the one gallon per 100 square feet. Too little, you may not meet the customer’s goal and service life will not be what it should be. Too much coating per coat means excessive cure times. This becomes especially risky in cooler temperatures and late in the season. We are a simple water clean-up family of products. Rain, fog, and dew are water. Once cured, our products will not re-emulsify (dissolve in water).

10) What do I do about standing water?
To the best of my knowledge, all current roofs are built with a pitch so the weight of standing water is eliminated, however, time tends to change things and low spots tend to occur. Standard coatings work well on pitched roofs but may take issue with prolonged standing water exposure. In these areas we recommend using Elasto-Barrier in conjunction with seam tape or fabric. Top coating with Maximum-Stretch, Snow Seal® or Iron Coat is recommended. The Elasto-Barrier is special; it is a non-breathable liquid rubber coating that can withstand ponding water. This means you could use Elasto-Barrier to seal a cardboard box and then store water in it!
