PRODUCT DESCRIPTION
Fast 2K™ is a more convenient and faster alternative than concrete
for setting posts, fences, signs and much more. Fast 2K™
is a two-part proprietary polymer that expands to fill the peripheral void
between the post and the hole, using the same technology applied
by H.B. Fuller to set utility poles for over 20 years. Because
of its expanding nature, one bag of Fast 2K™ replaces up to 2 x 50 lb
(25 kg) bags of concrete. Fast 2K™ expands immediately after mixing
and secures the post in the desired position within 3-5 minutes.
Fences can be installed in 15-30 minutes after Fast 2K™ finishes
expanding.
Fast 2K™ does not require water and becomes waterproof after fully
cured.
In addition to setting all types of fence posts (wood, vinyl, chain link
and ornamental), here are some other examples where Fast 2K™
can be used:
• Bollards
• Pergolas
• Mailboxes
• Signs
• Flagpoles
• Gate Posts
• Garden Light Post
• Clotheslines
• Posts for sport/athletic applications such as Basketball,
Soccer, Volleyball and Tennis
• Other light weight pillar foundation applications
USE & HANDLING INSTRUCTIONS
Before using this product and prior to removing outer black clip and
mixing contents, read and understand full instructions and warnings
listed on the label to avoid injury and property damage. Improper use
may be dangerous. Bag may rupture and contents may spray out
if bag is not cut open within one minute after removing outer black clip.
Immediately open the bag if any expansion in the bag is noticed. Part
A and Part B is packaged in a unique and convenient divided bag. The
bag is divided in the middle by an outer clip. (continued)

STORAGE AND USE
Shelf life is 24 months from date of manufacture.
Although there have been no changes in properties
of Fast 2K™ bags after 30 days at 5ºF (-15ºC),
we cannot guarantee the performance of the
product if bags have not been protected from
freezing. It is also important to keep in mind that
while Fast 2K™ can be used when ambient
temperatures range from -5ºF - 105ºF
(-20ºC - 40ºC), it is ideal to condition Fast 2K™
bags to 65 ºF - 80ºF (18ºC - 27 ºC) prior to use,
to provide optimal mixing and cure rate
performance.
