3.1 EXAMINATION

A. Verify that surfaces and conditions are ready to accept the Work of this section. Verify surfaces are clean, dry, sound and free of voids, deformations, protrusions and contaminants that may inhibit application or performance of the elastomeric coatings

Notify COR in writing of any discrepancies. Commencement of the Work in an area shall mean Installer’s acceptance of the substrate.

3.2 PREPARATION

A. Verify that the surfaces are clean and open texture.

B. Substrates must be clean, sound, dry, and absorbent free of surface contaminants or other contaminants deleterious to the penetration of the SACI. Remove dust, laitance, and grease, oils, curing compounds, form release agents existing coatings and all foreign particles by mechanical means. Substrate shall be in accordance with ICRI Guideline No. 03732 for sealers and fall within CSP1 to CSP3.

3.3 APPLICATION OF CONCRETE REPAIR AND PATCHING MATERIALS

A. Fill all visible hairline cracks and surface defects with appropriate Sika repair mortar

“or qual”, leveling mortar or surface filler prior to applying coating primer. Bugholes or irregularities of substrate shall be leveled with specified leveling mortar or surface fillers as appropriate.

3.4 CRACK TREATMENT FOR CONCRETE

A. For non-structural cracks, 12 mils or less apply the SACI in accordance with the

Product Data Sheet.

B. For non-structural cracks greater than 12 mils rout and seal the crack to a 1/4 inch by 1/4 inch profile and properly seal with a flexible, specified elastomeric joint sealant.

C. For structural static cracks, inject with a suitable epoxy.

3.5 APPLICATION OF SACI

A. The SACI is delivered ready to be used. No mixing is required and do not dilute on site.

B. Coverage is entirely dependent on the porosity of the substrate. Normally the consumption is achieved with 2 coats. Extremely porous substrates may only require 1 coat, very dense substrates may require 3 coats. To ensure proper penetration, a field mock up is required.

C. Placement Procedure: The SACI shall be applied liberally and allowed to soak into the substrate. This shall be accomplished by the use of brushes, rollers, low pressure gun or airless spray equipment.

D. On vertical surfaces, apply the product from the top down in successive passes until the targeted consumption for the first coat is achieved.

F. Successive passes are done when the concrete surface still has a matt appearance from the product, but is no longer wet (e.g. when placing the bare hand on the surface and removing it, no wetness on the hand is observed). The concrete surface is assumed to be saturated with the SACI when it remains “wet” in appearance for at least 5 seconds.

G. The following coat can then be applied when the concrete is completely dry.

H. On horizontal surfaces, saturate the substrate by continuous spray (airless or low pressure gun) or flooding technique and allow to have “wet” look for at least 5 seconds.

I. On soffit areas, apply the material with a continuous spray and saturate the substrate until surface keeps its “wet” look for at least 5 seconds.

J. Adhere to all limitations and cautions for the SACI product as stated in the manufacturers printed literature.

K. Do not apply the SACI in case of imminent rain (within the next few hours), strong wind exceeding 30 mph or in strong direct sun light.

3.6 APPLICATION OF SEALANTS

A. Provide the approved sealant system where shown on the Drawings, and in strict accord with the manufacturer's recommendations as approved by the COR.

B. Install sealants immediately after joint preparation. Mix and apply multi-component sealants in accord with manufacturer's printed instructions.

C. Install sealants to fill joints completely from the back, without voids or entrapped air, using proven techniques, proper nozzles and sufficient force that result in sealants directly contacting and fully wetting joint surfaces.

D. Install sealants to uniform cross-sectional shapes with depths relative to joint widths that allow optimum sealant movement capability as recommended by sealant manufacturer.

E. Tool sealants in manner that forces sealant against back of joint, ensures firm, full contact at joint interfaces and leaves a finish that is smooth, uniform and free of ridges, wrinkles, sags, air pockets and embedded impurities.

F. Remove sealant from adjacent surfaces in accord with sealant and substrate manufacturer recommendations as work progresses.

G. Protect joint sealants from contact with contaminating substances and from damages.

Cut out, remove and replace contaminated or damaged sealants, immediately, so that they are without contamination or damage at time of substantial completion.

3.7 FIELD QUALITY CONTROL

A. Notify COR when sections of work are complete to allow review prior to covering completed Work.

B. Cooperate with Owner’s inspection agency as applicable, who will observe substrate and coating installation and provide written documentation of observations.

3.8 CLEANING

A. Remove uncured materials from tools or other surfaces with an approved solvent.

B. Leave finished work and work area in a neat, clean condition without evidence of spillovers onto adjacent areas.

3.9 PROTECTION

A. Cap and protect exposed back-up walls against moisture and wet weather conditions during and after application of membrane. Protect Work against wet weather conditions for a minimum of 24 hours.
