SURFACE PREPARATION
Surface to receive Epoxy.com Product #308 Ultra Low
Viscosity Structural Bonding Epoxy must be clean and sound.
They may be dry or damp, but free of standing water.
For impregnating sealer application, substrate must be dry.
Remove dust, laitance, grease, curing compounds, impregnations, waxes
or other contaminants by sandblasting, abrading, or wire brushing.
If applied to steel, the steel should be sandblasted, wire brushed,
or prepared by other suitable means.
MIXING
Combine 2
parts Component A with 1
part Component B. by volume
The blend should be thoroughly mixed for at least three minutes with
an Epoxy.com -Mixing Paddle
on a low speed (300 to 600 rpm)
drill.
APPLICATION
Patching:
To prepare Epoxy.com Product #308 Ultra Low Viscosity Structural Bonding Epoxy
as an epoxy
mortar, slowly add approximately 3 parts by loose volume of Epoxy.com
Product #75 Filler to the mixed Epoxy.com Product #308 Ultra Low
Viscosity Structural Bonding Epoxy.
Floor Topping
Prime spalled areas with Epoxy.com
Product #308 Ultra Low Viscosity Structural Bonding Epoxy; apply with a broom or 3/8 nap rollers.
While prime coat is still tacky, fill level with Epoxy.com Product #308 Ultra Low
Viscosity Structural Bonding Epoxy Mortar. Use screeds to strike off level.
One-gallon of Epoxy.com Product #308 Ultra Low Viscosity Structural Bonding Epoxy, mixed with 3 parts by loose volume of Epoxy.com Product #75-Filler will produce
approximately 600 cu. in. of epoxy mortar.
Impregnation:
On smooth surfaces, apply approximately 112 sq ft / gal. of Epoxy.com Product #308 Ultra Low
Viscosity Structural Bonding Epoxy
with a rubber squeegee or roller to dry substrate.
Allow time to penetrate. Squeegee off excess while still liquid.
Concrete and Wood Injection: See
Epoxy.com Injection Methods.
LIMITATIONS
- Do not thin Epoxy.com Product #308 Ultra Low Viscosity Structural Bonding Epoxy;
solvents will prevent proper cure.
