For applications over pressure -treated lumber, please contact your Mer-Ko Representative prior to application. Slope must be a minimum of r/4 inch per linear foot to allow for proper drainage. Decks should meet local building codes. The deck shall be tongue and groove, completely blocked and nailed (glued and screwed is best). Plywood shall have a maximum joist span of 16 inches. Deflection should be less than L/360. OSB is not suitable substrate for this material. Moisture vapor commonly collects in areas below a vapor barrier, such as the waterproofing membrane of the deck covering system. Venting must be added to help relieve moisture vapor transmission. Please refer to all local building codes regarding venting requirements. PREPARATION Be sure the surface is clean, dry and free of grease, paint, oil, dust or any foreign material that may prevent proper adhesion. "Dry" plywood is typically defined as having less than a 10%moisture reading or by showing no moisture with a plastic sheeting test. Applicator is responsible for ensuring that the substrate is acceptable for application. Do not apply to wet plywood. APPLICATION INSTRUCTIONS In each step ofthe application, always besure that the previous coat has fully dried before applying the next coat. Read all instructions before starting application. FLASHING Install a minimum 26 gauge bonderized sheet metal 4"x 6"' wall to deck flashing where the deck meets the wall. Placethe 6-side up the vertical wall and a minimum 4"x 2" fascia flashing on deck edge, with the 4" side placed on the deck Nail in a staggered pattern every 4to 6 inches. Be sure to caulk all flashing seams and overlaps using MK-90 Polyurethane Caulking. (Note: Iftheflashing is not bonderized, it must be prepared in accordancewith SSPC-SP11 surface preparation standards, in order for the coating to adhere properly). SHEET MEMBRANE Mer-Ko requires the installation of 6 inch MK-62 Sheet Membrane to all plywood seams for reinforcement. For maximum protection, MK-62 36 inch, can be applied to the entire deck. MK-62 may also be installed behind or on top of the flashing as a backup waterproofing measure. For increased adhesion, MK-61 Sheet Membrane Primer may be used priorto applying the Sheet Membrane. MK-62 may not be leftexposed to the sun for more than 7 days. See MK-62 Sheet Membrane and MK-61 Sheet Membrane Primer Product Specification Sheets for additional information. METAL OR GLASS LATH The Shur Deck System can be installed with either the MK-70 Shur Deck Metal Lath or MK-71 Shur Deck Glass Lath. For maximum protection against corrosion, MK-71 Shur Deck Glass Lath should be used in lieu of MK-70. Place the desired lath on the plywood and cut it to fit the area ensuring the edge of the lath is offset two inches from any parallel plywood seams. The lath should run across the grain of the plywood (across the long seams) when possible. The grain of the metal lath should be placed so that it curves down atthe edge of the deck. When using the glass lath, unroll lath and place curl side down. Lath should be held back 2 inches from all deck edges, leaving 2 inches of flashing exposed. With the lath in place, start in the center working your way out. Staple the lath with MK-85 Shur Deck Staples, using a minimum of 22 staples per square foot. Overlap the lath 1-2 inches and staple every 1-2 inches along the seam. With a hammer, lightly pound down any seams or staples that are higher than the lath. When using the MK-71, ensure that the lath is secured properly to the plywood. This is especially true at all overlaps and edges. See MK-71 Shur Deck Glass Lath Product Specification Sheet for additional information. BASE COAT Pour 1 gallon of potable water into clean mixing bucket and then add one bag of MK-5 Shur Deck Cement. Mix until uniform with a mechanical mixer at a low rpm. Pour the mixture onto the metal lath and with trowel on edge, smooth the mixture to the top of the lath at the rate of 45 square feet per batch. Please note, if using MK-71 Shur Deck Glass Lath, coverage of the Base Coat will be 30 square feet per batch Trowel and brush the base coat up to the metal lath edge, leaving 2 inches of flashing exposed. For best results, tape off the flashing. Use a paintbrush to spread the base coat into all edges. Tap the deck lightly with a hammer to help in smoothing out trowel ridges. As soon as it is dry, usually 1 to 2 hours at 70 °F/ 50%RH, scrape off any high spots or ridges, before applying the Body Coat. Lower temperatures and higher humidity will require longer dry times. FLASH WRAP (OPTIONAL) For additional waterproofing and protection along the perimeter of the deck, Flash Wrap can be applied over the base coat. Install MK-80 Mer-Ko Burlap (101 to all vertical flash ings. Apply a coat of MK-25 Mer-Ko Membrane onto the vertical surface of and onto the adjacent horizontal surface by using a brush or roller at a rate of 100-150ft par gallon. Immediately embed the MK-80 burlap, fuzzy side down, into the wet MK-25, overlapping successive runs of fabric edges and ends, a minimum of 2 inches. Apply a coat of MK-25 at a coverage rate of 50 ft per gallon over the MK-80. Make sure the burlap is fitted tightly in corners and around protrusions. Apply additional MK-25 as necessary over the burlap fabric areas to ensure positive waterproofing is completely covering the burlap. The waterproofing membrane should be a minimum of 20 mils OFT Allow the Hash Wrap to dry for 4-6 hours before proceeding with the Body Coat. mer-ko.com 844-537-7203 Shur Deck Standard System Specification 10/2023 Page 2 of 4 SYSTEM COMPONENTS • MK-62 Sheet Membrane 6" x 75' (37.5 ft2 Rolls) 36" x 75' (225 It' Rolls) • MK-70 Shur Deck Metal Lath 27" x 97" OR • MK-71 Shur Deck Glass Lath 39.36" X 150' • MK-85 Shur Deck Staples 1 "x 5/e`-10,000 staples per box • MK-5 Shur Deck Cement 50 lb bag • MK-40 Mer-Ko Topcoat 5 gal pail (Optional) • MK-86 Slip Resistant Additive 32 ounce container • MK-6 Shur Deck Fine Cement 50 Ib bag • MK-80 Mer-Ko Burlap (10" Roll) 10" x 300' - 250 ft2 • MK-25 Mer-Ko Membrane (5 gal pail) • MK-61 Sheet Membrane Primer (i gal can) BODY COAT The Body Coat is applied in two coats. Mix 1 gallon of water to one 50 lb. bag of MK-5 Shur Deck Cement. Blend with a mechanical mixer for 2-3 minutes, until an even consistency is achieved. Trowel the material over the dry membrane surface at a rate of 90 ft2 per mix. Brush the mixed material onto the flashing and all vertical surfaces where bonding will occur and trowel apply to the entire deck surface as smooth as possible. Allow the first coat to dry for a minimum of 2 hours before applying the second coat. Repeat the process for the 2nd coat as mentioned above. An optional texture coat may be applied on top of the second application of the Body Coat. The Body Coat must be allowed to dry for a minimum of 2 hours at 70°F/50% RH or until dry to the touch before moving to the next step. Remove minor surface imperfections by lightly scraping or sanding. Be sure to remove all debris prior to commencing with the next step. TEXTURE COAT (OPTIONAL): An optional Texture Coat is prepared by mixing 1 gallon of water with each bag of MK-5 Shur Deck Cement. The Texture Coat is applied to the surface at a rate of 100-150 ft2 per bag. Allow the Texture Coat to dry a minimum 2 hours at 70"F, 50 percent relative humidity and then sand the surface to produce the desired level of finish. Ensure all dust and debris has been removed. For a smoother Texture Coat, MK-6 Shur Deck Fine Cement may be used in lieu of MK-5. Please refer to the MK-6 Product Specification Sheet for additional information. TOPCOAT Do not apply if rain is forecast within 48 hours or heavy dew within 24 hours. If multiple batches of MK-40 are present, box all materials prior to use, to ensure color consistency. Use a mechanical mixer at a slow speed and mix material until a homogeneous mixture and color is obtained. The material may be thinned by adding up to a maximum of one quart of water per gallon, for the first coat. For best results, it is not recommended to thin the final coat. Roll two thin applications of MK-40 using a 314 inch roller at a rate of 300-350 square feet per gallon. Roll the material in two directions to achieve a uniform finish. Coverage will vary according to texture. For best results, allow MK-40 4-6 hours drying time at 70 degrees before permitting light pedestrian traffic or additional coats are applied. Allow 24 hours to cure before heavy traffic is permitted. Allow 48 hours before heavy objects are placed on the surface and allow 72 hours for vehicular traffic. Allow 5 days prior to any abrasion or chemical exposure. SLIP RESISTANT ADDITIVE (OPTIONAL) To enhance skid resistance, mix 1 quart (32 ounces by volume) of MK-86 per 5 gallons of MK-40 Mer-Ko Topcoat (apply to the 2nd of the two coats). This will leave a consistent texture that is still fairly easy to clean. The actual slip resistance will be greatly affected by the existing texture of the surface you are covering and the thickness of the topcoat applied. Do not exceed this amount without consulting Mer-Ko.
