POLIBRID 670S is highly recommended for application to concrete substrates, especially damp surfaces such as those found in pump stations, manholes, cooling tower basins, secondary containment installations and other below-grade or at-grade structures. It is also recommended for application to metallic substrates when surface profile requirements for application of the POLIBRID elastomers direct to metal cannot be achieved. Call your regional technical service representative for specific recommendations.
- Important Limitation
Not recommended for application to wet surfaces. This product alone is not waterproofing. Concrete may to be primed may be damp to the touch but must be free of condensation and surface moisture. This product will neither repair leaks nor will it remedy excessive hydrostatic conditions.
- Surface Preparations
Allow a minimum 28 day cure period for new Portland Cement ASTM Type 1 concrete. Decontaminate per ASTM D-4258. Abrasive blast clean per ASTM D-4259 to remove laitance, loose concrete, existing coatings, and to produce surface profile resembling coarse sandpaper. Waterblasting alone or acid etching are not acceptable. Repair all leaks as directed by Engineer and eliminate standing water. If necessary, resurface with high-strength, rapid-curing, zero-shrinkage resurfacing product, before primer application. Concrete must be free of dust and contaminants prior to primer application.
- Mixing
Before using, agitate both components in their original containers for 5 minutes to produce complete suspension. Measure components at precise 1A:1B volume ratio, pour into clean separate container and blend by agitating mixed components for 5 additional minutes. Do not apply primer that has exceeded its usable pot life
- Recoat Window
For optimum results, topcoat before fully dried to the touch. Primer must be free of dust, moisture, condensation and contaminants before topcoating. If primer dries hard to the touch before topcoating, application of an additional coat of primer is recommended.
