SOUTHERN POLYURETHANES, INC.
Part Number:
#7000-1 Buff - Gallon
#8000-1 Grey - Gallon
#7001-4 Activator - Quart
Mix:
4:1
4 parts High Build Primer to 1 part High Build Primer Activator.
The primer can be reduced with our #860, #870 or #885 reducers if less millage is desired. This product should be reduced no more than 20% for best results.
CAUTION! Due to thickness of this primer it is very important that you completely mix the activator in with the primer. MIX ONE FULL MINUTE!
Spraying:
Mix only what you need! See pot life first! Spray one wet coat and let it flash 3-5 minutes, than apply a second coat. You can apply as many coats as you like, but it is very important that each coat flashes before applying additional coats.
Filling:
This primer, depending on the spray gun, will spray at 2-2.5 mills per coat. Industry standard is about 1.2-1.5, so if you are used to putting on 3 coats, 2 coats of this primer should be enough.
Sanding:
Depending on how it is applied, you should be able to sand this product in 30 minutes. Keep in mind this time changes with temperature. 2K High Build Primer sands good but to make it easier, shoot your coats to be blocked non-reduced and reduce you final coat 10-15% for less build and less final blocking.
Pot Life:
Short! Pot life will vary from 30 to 45 minutes depending on temperature, humidity and the amount of product in the cup. The more product, the shorter the pot life!
Summer Heat:
In the summer heat it will not hurt to add 2-4 oz of #885 reducer per mix quart of primer to avoid the potential of pinholes.
Winter: Add 2 –4 oz per quart of Polar Accelerator # 900-4 for cold shop
