3000 Q & A |
Does the substrate need
to be primed when pumping/pouring DRYTEK® 3000?
Yes. DRYTEK™ Primer should be diluted
with water according to the ratios given in the mixing guide below.
Water amounts should always be carefully measured in order to ensure
proper mixture is achieved. For best results, blending should be
performed by hand with a mixing paddle. [ Learn

|
What is the weight of
the DRYTEK® 3000? (per cubic Foot)?
DRYTEK® 3000 is roughly 30 lbs per cubic
foot after it has cured.
|
Which substrates can I
go over with the DRYTEK® 3000?
DRYTEK® 3000 can be applied successfully
over practically any structurally sound and solid substrate, but
on organic substrates such as wood, you may have to pretreat the
surface with a cover of plastic sheeting.
|
Is there a minimum and/or
maximum thickness at which the DRYTEK® 3000 can be applied?
Yes. The minimum thickness is ¾ of an inch,
however, there is no ceiling. (FYI- Maximum ever poured was 8 feet)
|
How long does DRYTEK® 3000 take to dry? Does it vary with pour depth?
DRYTEK® 3000 may be walked on (light foot traffic) after 12 hours and may be capped with a DRYTEK Self-Leveling product such as
DRYTEK 7400 after 24 hours. DRYTEK® 3000 is a fast drying product therefore drying times will not vary with pour depth.
|
Can the DRYTEK® 3000 be
barrel mixed and pumped?
Yes. However, a special mixer and mixing
paddle are recommended when barrel mixing. (CX60 mixer and the MX
160 mixing blade)
|
How long must I mix the
DRYTEK® 3000 when barrel pouring?
For at least 2-3 minutes.
|
Is the DRYTEK® 3000 a self-leveling
product?
It flows but not with the same 10-12 inch
slump of the other Drytek self-leveling products. It needs assistance
with either a rake or smoother.
|
Can I apply floor goods
directly on top of the 3000?
No. A minimum 1/2" cap must be applied
to the DRYTEK® 3000 prior to the application of floor covering.
|
What is the compressive
strength of the DRYTEK® 3000?
It is approximately 500 PSI. However, when capped with a minimum of 1/2" of Drytek 7400 it will achieve a PSI of 6,400.
|
| What is the working time
of the DRYTEK® 3000? |
What is the PH of the
DRYTEK® 3000?
The pH of DRYTEK® 3000 in its wet state is 12.5. The pH of the installed Drytek Flowlite system, which includes a base layer of DRYTEK® 3000 and topping layer of a Low-alkali Drytek leveling product such as Drytek 7400, is 11 in its wet state.
|
Can DRYTEK® 3000 be used
for exterior applications?
Yes, and is often used outdoors as geofill
material in the ground.
|
How long can the DRYTEK® 3000 remain exposed without being reprimed?
About 3 days. We suggest capping the 3000
within 1-2 days. This will eliminate any additional priming and
prevent any hairline cracks from forming in the 3000.
|
Are the lightweight aggregate particles going to be in the bag?
Yes. The lightweight particles are treated in a proprietary process
and then added to the cement at the factory and bagged.
|
| Can Drytek 7400, 9200,
& 9400 be used as finished floors/wear surfaces over the DRYTEK® 3000?
|
| Can DRYTEK® 3000 be used
for renovations as well as new construction? |
| Can DRYTEK® 3000 be applied
below grade, on grade, and above grade? |
| What is the size of the
bag (in lbs)? |
What is the coverage @
1 inch?
The yield at 1" thickness is 18 sq. feet.
|
| What type of cement is
it? |
Can it be applied over
moist or wet concrete?
Yes. However, it will not stop or repel
the moisture or alkalinity.
|
| Will the DRYTEK® 3000 be
compromised in any way if it is reintroduced to moisture/water?
|
Can DRYTEK® 3000 encapsulate
radiant heating?
DRYTEK® 3000 cannot encapsulate radiant heating but can be used underneath the radiant heating tubes. Drytek recommends placing radiant heating tubes on top of the DRYTEK® 3000, then capping with either DRYTEK 7600 or 7800. This prevents the loss of heat and will make the radiant heating system more effective and efficient.
|
What type of traffic can
be used on the DRYTEK® 3000 after capping it with Drytek 7400, 9200,
& 9400?
All three products will handle commercial
foot traffic at 3/8" (ie. retail stores, museums, offices, etc.)
For more demanding applications such as forklifts, rolling carts,
heavy compressed loads, etc. please contact your local Drytek representative
to assist in customizing a floor assembly for your specific needs.
|
| What is the minimum substrate
temperature when pouring DRYTEK® 3000? |
| What is the shelf life
of the DRYTEK® 3000? |
What about storage of
DRYTEK® 3000?
DRYTEK® 3000 must be kept dry and stored
in a dry atmosphere.
|
What type of floor prep
is required prior to pouring or pumping this product? (ie. Shotblasting)
Provided the substrate is free of any contaminants
that may contribute to decreased bond (ie. oil, grease, dirt, dust,
etc) the surface bond strength of the substrate must be a minimum
of 72 PSI. Please contact a Drytek representative to have a surface
bond strength test performed for you.
|
Are there any Drytek products
that can not be used over the DRYTEK® 3000?
Yes. Drytek 7000, 8200, & 8400 shall not
be used over the DRYTEK® 3000.
