First, you need a clean surface. Pressure washing the surface is
preferred. After the surface is clean you will need a garden type
pump up sprayer. Temperatures must be above 35 degrees
throughout the sealing process.
1) Wet the surface of the concrete with fresh water as to leave it
damp. Avoid over application which will result in standing water
on the surface.
2) Apply 2 applications of HydraSeal waiting 15-20 minutes
between coats but no longer than 45 minutes.
3) 6-8 hours after the final application of HydraSeal,
scrub the surface with fresh water and a stiff bristled deck
brush. This will break down any residual sealer that is left on
the surface.
4) Allow HydraSeal to complete the 10 day purging process;
any contaminates or impurities my be swept or vacuumed from the
surface.
5) After 10 days have passed, apply two consecutive applications
of CS-20 again, waiting 15-20 minutes between applications.
The first application of CS-20 must still be damp when the
second application is applied. Apply in sections if necessary.
6) Stay off the concrete for at least 36 hours as to not damage
the seal.
PLEASE READ EXCEPTIONS
Paint or other products must be removed from the
concrete. Usually this requires shot blasting, acid etching, sand
blasting, dry ice blasting, or even the use of a good paint
stripper.
Colored concrete can not be sealed with HydraSeal
as it may discolor the concrete or leave the color blotchy. You may
use either CS-20 or the CS-20 Plus with no pre-sealer
in this case. |
