I just finished texturing my kitchen with Behr Texture paint. Now I
want to put on a topcoat but do not understand the instructions below.
It says it takes 2 hour to dry to touch and 1 week to fully cure. Do I
need to wait the full week? Please clarify.

Application For Smooth and Sand Finishes
* Use product when the surface and air temperatures are between
50=B0 - 90=B0F (10=B0-32=B0C).
* Stir occasionally. Coverage is 100-200 sq. ft. per two-gallon
container depending on application technique and surface
condition.
* Try your technique on a practice board before applying to
walls.
* Work in 4'x 4' areas, apply product using a looped roller.
* While the product is wet, create your final design using a
looped texture roller, sponge, putty knife, trowel, broom
or short nap roller.
* Topcoat with BEHR PREMIUM PLUS Paint if a color change is
desired or for additional protection.

Dry Time
* Dries to touch in two hours at 75=B0F (23=B0C) and 50% humidity.
Longer dry time required in cooler temperatures and in
higher humidity.=20
* Surface will fully cure in one week.

From Behr's website, specifically the decorative topcoat instructions

How Do I Prepare The Surface?
Allow to dry completely according to label instructions.
Wipe all surfaces being topcoated with a damp cloth to remove any dirt or
dust.
On previously stained wood surfaces, where the surface topcoat is in good
condition, thoroughly clean with a heavy duty industrial cleaner or wax
remover. Allow to dry then sand with fine grit sandpaper. DO NOT USE STEEL
WOOL. Wipe with a damp cloth
-----------------

bullet one seems to indicate that you're gonna have to wait a week to apply
it.

From the same website but this time from the Sandwash instructions
----------
If applying in high traffic or high moisture areas, use BEHR CRYSTAL CLEAR
WATER-BASED POLYURETHANE. Apply this product after the SANDWASH finish has
cured 7 days. This will darken the tone and/or color of the SANDWASH finish.

That pretty much sounds like your answer right there.

Thanks
