SEALTIGHT®
ACRY-LOK™
AN ACRYLIC POLYMER, BOND-ENHANCING, ADMIXTURE
DESCRIPTION
SEALTIGHT ACRY-LOK is a high solids, acrylic
polymer latex bonding agent and admixture. This milky white liquid is
non-yellowing in Portland Cement compositions. When used as an admixture,
ACRY-LOK provides better crack resistance, flexural strength, and freeze / thaw
tolerance. Permeability is reduced, allowing more protection from chloride
intrusion.
As a bonding agent, ACRY-LOK enhances the bond between
existing concrete and placement of a fresh repair. It will not re-emulsify.
USES
Since ACRY-LOK will not re-emulsify, concrete
repairs / mortars fortified with ACRY-LOK are ideal for interior, exterior and
moisture related applications. Typical areas that would benefit from properties
of this product include toppings, mortars, grouts, vertical, horizontal and
overhead patching. Use ACRY-LOK neat as a bonding agent or as an additive in
scrub coats prior to repairs or overlays.

PRECAUTIONS / LIMITATIONS
| Designed for professional contractors, industrial use
only
| Do not allow to freeze, properly dispose of any
material that has been frozen
| Do not apply ACRY-LOK when temperature is expected to
be below 40°F (4°C) within 48 hours or when rain is imminent.
| Avoid over-mixing and over-working the surface
| Do not use with air entrained cement
| Do not use with solvent-based curing compounds |

SAFETY AND TOXICITY
Avoid direct contact with this product. Use of
safety glasses, rubber gloves and protective clothing is recommended. If contact
occurs, wash affected areas with mild soap and water. Keep product out of reach
of children. FOR INDUSTRIAL USE ONLY. Refer to Material Safety Data Sheet for
complete health and safety information.
SURFACE PREPARATION
Mechanically abrade existing substrate to remove
all unsound concrete, but do not use excessive force which may cause micro
fracturing. Substrate must be structurally sound and free of grease, oil, dirt
or any other contaminants that can adversely affect the bond. Prepared surface
must be dust-free and have sufficient profile to ensure adequate mechanical
lock. Substrate must be saturated, surface dry (SSD) and free of standing water.
APPLICATION
AS AN ADMIXTURE
Typically, blend one part cement to three parts
sand then add enough ACRY-LOK until a desired consistency is achieved. To avoid
trapping air, do not over mix. Place modified mortar / repair material and
finish appropriately, careful not to overwork the material. Once the finishing
process is completed, immediately cure work zone with undiluted ACRY-LOK or one
of several MEADOWS’ water-base curing compounds. Do not use solvent-base
curing compounds.
AS A SLURRY COAT
Mix one-part cement to two parts sand, then add
enough undiluted ACRY-LOK to make a slurry consistency. Work slurry into the
repair area with a stiff masonry brush, coating the entire area, paying special
attention to the corners, sides and any exposed rebar. Place modified mortar /
repair material prior to ACRY-LOK becoming tack-free.
AS A BONDING AGENT (NEAT)
Apply ACRY-LOK undiluted by brush, roller or
garden type sprayer on prepared surface. Place modified patching/repair material
before prepared ACRY-LOK surface dries.
MIXING AND APPLICATION NOTES
Mix designs vary with specific job requirements.
Proportioning of sand, cement and ACRY-LOK (Diluted or neat) ratios achieve
different physical properties. The application instructions highlight typical
conditions. (When in doubt, always apply a test patch).
