INSTALLATION

DIRECTIONS FOR USE

Most professionals prefer to cut the ends

of Big-Stick at a 45º angle.

Properly mix all-purpose compound per

manufacturer’s directions. If applying

Strait-Flex tapes over painted surfaces, add

Strait-Flex’s Super-Bond or latex paint to

compound to enhance bondability.

Run your taping knife over the surface of

the drywall and remove any high spots. If

the knife hits a screw head, set the screw

a little deeper. Use a drywall rasp to clean

up edges, if needed. Measure wall height

and subtract 1/2”. Measure and cut Big-

Stick using a scissors or utility knife.

Press Big-Stick into the wet compound.

Adjust if necessary to create a straight line.

For high volume applications, use Big-

Wipe down tight with taping knife using a

little additional pressure on the outer edges

of Big-Stick. Immediately apply a light

skim coat of compound over surface. Wipe

down tight and smooth. Let dry completely

over several hours or overnight.

With a 6”or 8” taping knife, apply your

ﬁnal coat of compound feathering the

compound beyond previous coat. Let

dry completely over several hours or

overnight.

Sand lightly with 120 grit sandpaper. Big-

Stick will not fuzz-up like paper or mesh

tapes.

Have a ﬁve-gallon bucket of water with a

durable sponge handy for cleaning tools.

When painting, apply a base coat of drywall

primer to seal the compound and assure an

even paint ﬁnish.
