2) Joints and surfaces, which are to be caulked or sealed, shall be clean, dry, frost free, free of dust, loose mortar, and other foreign materials. 3) Temperature Installation Requirements: 40ºF minimum application temperature for joint sealant installations because of the possibility of moisture and/or frost contamination on sealing surfaces: (Comply with sealant manufacturer’s written recommendations)
a) However, it is recognized that applications may have to be made at lower temperatures. When this is necessary, steps must be taken to assure dry, frost-free surfaces and is the responsibility of the caulking subcontractor. Additionally these procedures must be in compliance with sealant manufacturer’s written recommendations.
4) Clean ferrous metals of all rust, mill scale and temporary coatings by wire brushing, grinding, or sandblasting.
5) Remove oil and grease with high performance cleaners as approved by sealant manufacturer.
6) On joints adjacent to porous substrates install appropriate primer prior to application of sealant.
7) Joint dimensions for sealant should be reviewed and installed in accordance with sealant manufacturer's printed instructions. In no case should the sealant application be less than 1/4" wide and 1/2" deep, except in specific metal-to-metal curtainwall applications and then as recommended by the sealant manufacturer. 8) Precast concrete, cast-in-place concrete, or masonry joint surfaces shall be wire brushed, then brushed clean or blown clean with dry, oil free compressed air. a) The joint interface must be free of form release agents, curing and sealing compounds or chemical retarders which may interfere with sealant cure, adhesion and performance.
9) Sealants shall not be applied to masonry joints where a water repellent or masonry preservative has been applied prior to caulking.
a) Waterproofing treatments shall be applied after caulking. 10) Do not caulk joints until they are in compliance with requirements of the approved manufacturers of the materials, the details as shown on the drawings, and the specific requirements of other sections of this Specification.

e) Tool – Dry tooling techniques are used to strike a flush joint and make certain the sealant has the proper configuration and fully contacts the joint walls. 2) Clean – Substrate Cleaning Procedures
a) General procedures for porous and non-porous substrates key to good sealant adhesion is a clean surface. Always check with the supplier of the substrate to ensure that the cleaning procedures and solvents are compatible with the substrate.
i. Organic Solvent Usage
a. Not every contamination is effectively removed by every solvent, and some substrates can be seriously damaged by certain solvents. Please follow the solvent manufacturer’s safe handling recommendations and local, state and federal regulations regarding solvent usage. ii. Non-Porous Substrates
a. Non-porous surfaces must be cleaned with a solvent before the sealant is applied.
b. Use the “two-cloth” cleaning method explained later in this section. iii. Porous Substrates
a. Building materials such as EIFS, cement board panels, concrete, granite, limestone and other stones or cementitious materials that absorb liquid are considered porous substrates.
b. Dusting alone may be sufficient cleaning for new porous substrates.

Depending on the condition of the surface, porous substrates may require abrasion cleaning, solvent cleaning or both. Laitance and surface dirt must be completely removed. Concrete form-release agents, water repellents and other types of surface treatments, protective coatings, and old sealant all affect sealant adhesion. Removal of these treatments, coatings or sealants by abrasion cleaning may be required to obtain acceptable adhesion.
c. Abrasion cleaning involves grinding, saw cutting, sand or water blasting, mechanical abrading or a combination of these methods. Remaining dust and loose particles should be removed by dusting the surface with a stiff brush, vacuuming, or blowing the joints with oil-free compressed air.

Once the abraded surface is clean and dry, the sealant can be applied. If the surface is dirty, it must be solvent cleaned with the “two-cloth” method explained later in this section. Some porous materials will trap solvents after cleaning or priming. Allow this solvent to evaporate before sealant is applied.
d. Please note sealant recommendations for removal of existing sealants, substrate cleaning, joint preparation and installation of sealants are not intended and may not be appropriate for remedial work involving City of Roseville 19six Architects Project No. 210015.01 Dry Creek Wastewater Treatment Plant AHJ Project #: XX-XXXXXX Operations and Lab Building

existing sealants and/or joints containing PCB’s, asbestos, or other potentially hazardous substances. If you know or suspect that the existing sealants and/or joints contain PCB’s or other hazardous substances, contact project Owner General Contractor and a knowledgeable authority on appropriate removal, handling and disposal procedures.
iv. Masking
a. Silicone primers and sealants cannot be removed with organic solvents.

It is imperative that uncured silicone primers and sealants do not contact non-abradable surfaces where the silicone is not intended. Mask these surfaces or use extreme care to prevent any silicone contact with the surface during priming and sealant application.
v. “Two Cloth” Cleaning/Priming Method
a. (Using DOW CORNING P5200 Cleaner/Primer)
i). Clean, soft, absorbent, lint-free cloths must be used. The two-cloth cleaning method consists of a solvent wipe followed by a dry cloth wipe.
ii). Thoroughly clean all surfaces of loose debris. Mask or tape joints before applying Cleaner/Primer. If a bond breaker tape will be used instead of backer rod, the tape should be applied before the cleaner/primer.
iii). Clean and apply Cleaner/Primer product in accordance with manufacturer’s written recommendations.

2. Tapes
a. Prepare per manufacturer’s recommendations.
b. Prime as required by manufacturer for each specific tape.

3.4 INSTALLATION
A. Sealant

1. General:
a. Clean, prime and apply materials in accordance with printed recommendations of manufacturer of material used.
b. Insure that if two sealant-curing types are used which have different curing times, that the first installed sealant is fully cured prior to the application of the second sealant. 1) Confirm application with sealant manufacturer.
c. Insure that if two different sealant composition types are used, that the proper sealant is installed first to insure adhesion between the two different sealants. 1) Confirm application with both sealant manufacturers.

d. Install joint backing with a blunt instrument so as not to puncture the surface skin. 1) Size of closed cell joint backing should be determined by adding 25% to the joint width to assure proper compression of the rod.
2) With other types of joint backing, consult manufacturer's printed instructions for proper use.
e. Apply sealant with a caulking gun, using proper nozzles. Use sufficient pressure to properly fill the joints with sealant to the backup material.
1) After joints have been completely filled, they shall be neatly tooled to eliminate air pockets or voids and to provide a smooth, neat finish in intimate contact with interfaces. Dry tooling is preferred.
2) After tooling, surface of sealant shall be free from ridges, wrinkles, sags, air pockets and embedded impurities.
f. Immediately clean adjacent materials, which have been soiled. Leave work in a neat, clean condition.
g. Joint Dimensions
1) Size and shape as shown on Drawings but not to exceed joint size recommended by sealant manufacturer.
a) Typically install backer rod at all joints unless specified to be bond breaker tape, other material as specified and /or detailed or no backer material in accordance with sealant manufacturer's printed directions.
i. Sealant depth to width ratio shall be installed in accordance with sealant manufacturer’s written instructions.

2. Silicone:
a. General:
1) Apply materials in accordance with printed recommendations of manufacturer of material used.
b. Schedule:
1) Prime – Primer Application Procedure
a) DOW CORNING P5200 Cleaner/Primer Coat should be applied as follows:
i. Joint surfaces should be clean and dry.
ii. Apply masking tape to the surfaces next to the joint to keep excess primer and sealant off areas where they are not intended.
iii. Apply Cleaner/Primer in accordance with manufacturer’s written recommendations.
2) Pack – Packing with Backer rod / tape
a) Moving Joint Considerations

Project Specifications
SEALANTS AND CAULKING 07 92 00 - 24
i. When designing moving joints, the following points also need consideration:
a. A minimum ¼” joint width is recommended. Wider joints accommodate more movement than narrow joints. (Refer to Drawings for design intent joint widths)
b. Three-sided adhesion limits the amount of movement that a joint accept without inducing a tear. Three-sided adhesion can be eliminated by the addition of a bond breaker tape or backer rod. With three-sided adhesion, no more than +15% movement can be accommodated. c. A thin sealant joint (1/4” + 1/8” depth) will absorb more movement than a thick joint. Sealants are designed to deliver optimum performance when the joints are shaped like an hourglass
d. As a practical matter, as the sealant joint width becomes larger than 1”, the depth should be held at approximately 3/8”. There is no need to increase the depth beyond 3/8”.
b) Movement During Cure
i. One-part sealants cure by taking moisture out of ambient air. Joint movement during cure can cause unsightly aesthetics due to joint wrinkling. Premature adhesion loss can also occur because the adhesive characteristics of the sealant are obtained after the sealant has cured. Adhesion loss due to movement during cure can be minimized by the use of a primer. Primers can decrease the adhesion cure time lag. Minimize wrinkling by following these suggestions:
a. Use open-cell polyurethane backer rod / tape in non-EIFS or vertical applications.
b. Seal when the joint surface is cool and will experience minimum temperature changes, typically in the late afternoon or early evening. c. Place no more than 1/4” of sealant over the backer rod / tape at the center.
3) Shoot – Sealant Application Procedure
a) It is critical that the sealant fills the entire joint or cavity and firmly contact all surfaces intended to receive sealant.
b) To obtain full adhesion, sealants require a clean, dry, frost-free surface. c) Sealant shall be applied as follows:
i. As previously indicated, masking tape should be used to keep excess sealant from contacting adjacent areas where it is not intended to ensure an aesthetically-pleasing job.
ii. Apply the sealant in a continuous operation using a caulking gun or pump. A positive pressure, adequate to fill the entire joint width, should be used. This can be accomplished by “pushing” the sealant ahead of the application nozzle.

Care must be taken to ensure complete fill of the sealant cavity. 4) Tool

a) Tool the sealant with light pressure before a skin begins to form (typically 10 to 20 minutes). Tooling forces the sealant against the back-up material and the joint surfaces. Do not use liquid tooling aids such as water, soap or alcohols; i.e. These materials may interface with sealant cure and adhesion and create aesthetic issues. b) Remove the masking tape before the sealant skins over (within about 15 minutes of tooling).
