	[ Click Here ] for additional information. Foster Products brand is owned by Specialty Construction Brands, Inc. a wholly owned subsidiary of the H.B. Fuller Company. Foster Products has provided solutions to customers since being founded in 1909. The FOSTER and CHILDERS brands of mastics, coatings, adhesives and sealants are owned and marketed by SCB. Foster is truly a global supplier with an international presence and operations on five continents. Foster Products focuses on serving the North American market by supporting an extensive and superior distributor network selling FOSTER and CHILDERS brand products. Globally, Foster works through a licensee network and by direct export. The Foster Products production facility in Houston, Texas operates under ISO 9001 quality system certification. As a reflection of the construction industry's growing concern over mold, the market has been flooded with building products claiming resistance to mold growth. To date, only the Foster ®Business has taken the lead in putting its coatings through the rigorous testing necessary to establish how effectively the coating surface resists mold growth under harsh real-world conditions. In multiple rounds of internal and independent testing, Foster ®42-42TM Mold Resistant Sealer has been shown to provide a dry film which exhibits superior inhibition to fungal growth under unaged and aged conditions. Foster ®42-42TM Mold Resistant Sealer is ideal for use on: trusses, wood studs, gypsum wall board, plywood, plaster, cement block, sheathing and many other materials to provide mold resistant surfaces. Provides water resistance to the substrate, while not restricting water vapor transmission, allowing moisture in materials to dry and inhibit mold growth. .

	** NOTE TO SPECIFIER ** ASTM D-5590 is specifically designed to test paints and coatings in the most severe environment possible for promotion of fungal growth. The tests show that Foster ®42-42TMMold Resistant Sealer exhibited excellent resistance to mold growth both in initial testing and after aging with the best rating of "0: No growth" in the tests conducted. The testing performed by two different independent microbiology laboratories gave results matching those found by in-house testing confirming the performance of Foster ®42-42TMMold Resistant Sealer and the validity of the test results. This product does not protect users or others against bacteria, viruses, germs, or other disease organisms. It does not take the place of normal cleaning & disinfecting procedures. Not recommended for long-term exposure to direct sunlight.

	PART 3	EXECUTION
	3.1	EXAMINATION
		A.	Do not begin installation until substrates have been properly prepared.
		B.	Wood Substrates: Clean and dry.
		C.	Concrete Substrates: Cured at least 72 hours and free of contaminants that affect adhesion.
		D.	Masonry Substrates: Cured at least 72 hours.
		E.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
	3.2	PREPARATION
		A.	Clean surfaces thoroughly prior to installation.
		B.	Remove contamination such as oil, form-release agents, waxes, paint, dust, and dirt. Use methods appropriate to type of substrate and contamination encountered, such as scrubbing with detergents, acid etching, scarification, and sandblasting.
		C.	Existing Painted Substrates: Remove loose paint that may impede bonding. Use method that does not damage substrate.
		D.	Pre-clean surfaces with extreme mold or mildew contamination that would effect the penetration and adhesion of Foster 42-42 to assure a good bond. Remove in accordance with the recommendations of the sealer manufacturer.
		E.	Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
		F.	Protect all adjacent surfaces and materials not receiving coating from overspray; mask when necessary to provide adequate protection. Repair damage.
	3.3	INSTALLATION
		A.	Install mold resistant coating in accordance with manufacturer's instructions.
		B.	Apply uniformly to required surfaces by brush, spray, or roller.
		C.	Do not apply additional coats to surfaces that are not dry. Allow applied coats to dry before next coat is applied.
		D.	Apply in uniform coats, avoiding runs, drips, pinholes or other finish variations. Finish edges, crevices, corners, and other changes in dimension with full coating thickness.
		E.	Apply evenly to gypsum wallboard surfaces at the rate of 450-550 SF/gallon (11.0-13.5 sm/l) until the surface is well saturated and remains wet.
		F.	Apply evenly to wooden surfaces at the rate of 250-350 SF/gallon (6.1-8.6 sm/l) until a uniform wet, thin film remains on the surfaces.
		G.	On hard nonporous surfaces such as hardwoods or finished concrete apply at the rate of up to 600 SF/gallon (14.7 SM/l). Rolling or brushing will provide faster penetration than spraying.
		H.	Allow the coating to completely dry through before overcoating. A single coat application is all that is required. Minimum dry time: 1 hour.
	3.4	CLEANING
		A.	Clean surfaces immediately of overspray, splatter, and excess material.
		B.	Use fresh water to clean equipment before product dries. Dry product may be removed with undiluted pine oil or citrus-based cleaners, or with nonflammable chlorinated solvents.
	3.5	PROTECTION
		A.	Protect installed products until completion of project.
		B.	Touch-up, repair or replace damaged products before Substantial Completion.
	** NOTE TO SPECIFIER ** Include schedule if required to identify locations of surfaces to receive mold resistant coating. Use schedule in conjunction with the drawings. The following is an example of a typical schedule. Modify as required to suit the project requirements.
	3.6	SCHEDULE
		A.	Apply one coat of Mold Resistant Coating to the following surfaces:
			1.	Interior surfaces of sheathing and gypsum board in exterior walls.
			2.	Interior surfaces of wood framing, sheathing and gypsum board on walls in Kitchens, Shower Rooms, Toilet Rooms, Janitor Closets.
