1.0 EIFS Siding Repair:

1.1 – Cleaning: Note: No water source is available at the site and protect wood surfaces to be painted from getting wet during power washing of siding. Thoroughly wet the entire wall to be cleaned prior to the application of the cleaning solution. Apply cleaning solutions using a low-pressure sprayer, 30 to 50 psi. Complete an entire wall application at one time in order to prevent “clean streaking”. Acceptable cleaning solutions are the following:

Prosoco Lawrenceville, KS 60046

(800) 255-4255

Enviro Klean® EIFS Clean ‘N Prep

Shore Corporation Pittsburgh, PA 15210

(800) 860-4978

2600 EIFScrub

ABR Products, Inc.

Franklin, WI 53132

(414) 421-4125

Building Wash 3

The pressure used must be adequate to coat the finish surface with the cleaning solution and not more.

Chemicals in the cleaner provide the cleaning action, not the force of the water spray used to apply the cleaner. Scrub the EIFS surface with a soft bristle brush following the cleaning solution manufacturer’s instructions for application and scrubbing. Caution: DO NOT use high pressure to apply cleaning solutions, as the solution may be driven through the finish and into the base coat, and become the source of future staining. Rinse the wall with large amounts of clean, pressurized water from top to bottom before the cleaning solution can dry. Higher pressure (< 600 psi) should be used for the water rinse to remove surface contaminants that have been lifted by the chemical action of the cleaning solution, and also to remove any residue of the cleaning solution itself. Exercise care with the higher pressure so as not to damage the finish. Allow surfaces to dry for 36 hours before application of new coatings.

1.2 Sealant Replacement – Remove and replace all caulking/sealants in joints, penetrations/openings and along edges of the EIFS system. Cut out and dispose of existing sealant. Prep surface and install new sealant primer and sealant per the manufacturer’s requirements. Acceptable sealant sources are as follows:

Tremco, Inc.

Sealant: Spectrem 1, Spectrem 3 and Spectrem 4 Primer: TREMprime Silicone Porous Primer

Pecora Corporation Sealant: Dynatrol II Primer: Type 75 or 150

Pecora Corporation Sealant: 890 Silicone Primer: P75

Sika Corporation Sealant: Sikaflex 2C Primer: Sikaflex 429*

Dow Corning Sealant: Dow Corning 790, 791, 795 Primer: Dow Corning 1200 Prime Coat

1.3 – EIFS Repair: Repair any existing damage/holes in the EIFS surface by repairing finish and/or removing the damaged areas and installing new insulation, mesh, base and finish coats; all per the EIFS manufacturer published repair guidelines. Submit a copy of the EIFS manufacturer repair manual/guidelines to the COR previous to the start of work to identify and discuss the damaged areas to be repaired and the appropriate repair methods to be used.

1.4 – Elastomeric Coating: Allow the EIFS surface a minimum of 36 hours after cleaning/repair to completely dry. Install 2 coats of Dryvit Weatherlastic Smooth elastomeric coating per the manufacturer’s requirements. Protect newly installed caulk/sealants from damage during application of coating. Note: Elastomeric Coating cannot be applied previous to sealant as the Weatherlastic product will prevent proper adhesion of the sealant to the EIFS surface. Select Weatherlastic color from standard manufacturer color chart to match existing EIFS finish color.

2.0 Painting -

2.1 Wood - Scrape/wire brush peeling wood surface to remove loose paint. Protect wood surfaces from getting wet during power washing of siding. Prime with 1 coat of Sherwin Williams or approved equal exterior oil-based wood primer followed by 2 coats of Sherwin Williams or approved equal Sher-Cryl

HPA.

2.2 Steel Vent Hoods – Scrape/wire brush and power wash surface to remove loose paint and dust/debris. Allow to dry and apply 1 coat of Pro-Cryl or equal universal acrylic primer and 2 coats Sher-Cryl or equal HPA top coat.

2.3 Concrete Foundation – Scrape 2” of existing rock surfacing away from foundation and wire-brush surface to remove dirt and loose paint. Power wash/rinse surface and prime with an exterior masonry primer and then 2 coats of Sher-Cryl or equal HPA top coat. Push/level rock back against foundation.

3.0 Vinyl Soffit Installation –

3.1 Install a vented vinyl soffit system similar to Ply Gem Economy Triple 4” (T4) vented soffit under the roof overhang. Install joist hangers from the existing framing and 2”x6” joists in the new hangers with mid-span wire hanger supports as necessary to provide minimum manufacturer required support for new panels. Vinyl soffit panels shall be installed per manufacturer’s instructions using exterior rated fasteners with required spacing and type/depth to allow for panel expansion and contraction. See example photo’s below.

4.0 Prep/Paint Bollards:

4.1 Prep by removing any loose paint/rust with a wire brush and lightly sand surface with 100 grit abrasive. Powerwash surface to remove dust/residue and allow to dry completely. Prime with 1 coat of Sherwin Williams Chem Chromic or equal enamel primer and 1 topcoat of a bright red Sherwin Williams DTM or equal finish.

5.0 Clean-up: After the satisfactory completion of the above work and before leaving the site, the contractor shall clean up and dispose of/remove all trash, refuse, excess material, etc. leaving the site in its original condition.
