Description

Sikadur 51 NS is a 2-component, non-sagging, solventfree, moisture-tolerant, flexible epoxy control joint sealer and adhesive. Questions? Contact Us.

SUBSTRATE PREPARATION:
Substrate must be clean and sound. It may be dry or damp, but free of standing water. Remove dust, laitance,
grease, curing compounds, impregnations, waxes, foreign particles, disintegrated materials, etc., by mechanical means (i.e. sandblasting, high pressure water blasting).

MIXING:
Pre-mix each component. It is critical to accurately proportion 2 parts Component ‘A’ and 1 part Component ‘B’ by volume into a clean pail or appropriately sized mixing container. Mix thoroughly for 3 minutes with a Sika Paddle on a low-speed (400–600 rpm) drill until uniform in color. Mix only that quantity which can be used within pot life.

APPLICATION METHOD / TOOLS:
For vertical or overhead applications, gun Sikadur®-51 NS into construction/control joints and cracks with caulking gun, pressure extruder, or other suitable methods. Be sure to maintain steady pressure and steady flow of material, filling entire joint in a single application. Take care to eliminate overlapping as this may cause bubbling within the material. For use as a flexible adhesive, consult Sika Technical Service at 800-933-SIKA.

LIMITATIONS:
Do not thin Sikadur®-51 NS. Addition of solvents may prevent proper cure.

Substrate temperature should be 40 °F (4 °C) minimum and rising.

For best results, materials should be maintained between 65–85 °F (18–29 °C) during application.

▪ Do not apply through standing water.
▪ Minimum age of concrete is 28 days.
▪ Materials are vapor barriers after cure. Concrete or masonry must be tested for water-vapor transmission prior to application.

Not designed for use under constant immersion in water or other liquids.
▪ Do not use in expansion (moving) joints.
▪ For application in non-moving joints only. The ultimate performance of Sikadur-51 NS depends upon many factors, [i.e., proper joint design, thermally stable areas, (concrete slab), etc.].

For applications other than sealing of control or construction joints, consult Sika Technical Service at 800-933-SIKA.

Not an aesthetic product. Color may alter due to variations in lighting and/or UV exposure.
