Prime Coat |
|
|
For old, oxidized pavements, a primer coat is recommended.
The
suggested materials are noted below;
A. diluted with clean potable water in 1:3 volume ratio (sealer;water)
applied at 0.04 to 0.06 Gal (undiluted sealer)/ Square Yard.
B. Star One Step, diluted with clean potable water in 1;2 volume ration (Star One
Step;Water), applied at 0.05-0.08 gal. (mixed)/Square Yard. |
|
|
|
CURING TIME |
|
|
Will vary according to temperature and relative humidity at
the time of application.
Under ideal conditions (77F and 50 % R.H.) allow at least:
4-6 hours between coats
24 hours after application of the last coat, before opening to vehicular
traffic. |
|
|
|
WEATHER LIMITATIONS |
|
|
Surface and air temperature should be a minimum 50 F and rising.
Do not apply on rainy, foggy, or extremely humid days, or if rain is in the forecast
within 24 hours.
Dampen the pavement with a fine mist of water if the surface temperature is over 85 F to
facilitate even spreading. Do not allow water to puddle on the surface. |

TECHNICAL RESEARCH |
|
|
|
The two most important factors in
sealcoating strength and longevity are resistance to water absorption
and traffic abrasion. The following demonstrate why Star-SealŪ performs so well in "real world" situations. |
|
|
|
|
|
 |
WATER ABSORPTION PROFILE
The cured films of sealcoatings have varying
degrees of water absorption, depending upon the water sensitivity of the
ingredients used in their formulations.
Star-SealŪ
is formulated the least water sensitive ingredients and is
therefore least affected by the problems associated with water
absorption. |
 |
SCRUB RESISTANCE UNDER WATER
(ASTM
D-2468 modified)
The cured films of sealcoatings frequently
encounter rain, snow and sleet. It is extremely important that these
films retain their performance properties under such conditions and not
be prematurely eroded by traffic.
The scrub resistance test has
consistently proven Star-SealŪ to have excellent
durability under water. |
