AQUAFIN®-2K/M • Repair holes, defects, irregular surfaces, weak mortar joints, etc. with MORTAR-40 CI, MORTAR-V/O CI or MORTAR-LN. • Round edges at vertical external joints. • Close large open pores and joint recesses of CMU blocks and joint unevenness in brick walls with MORTAR-V/O. • Dampen substrate with clean water to saturated surface dry (SSD) condition, with no standing surface water. • Roughen fiberglass substrates using diamond grinding, zek/wire wheel, etc. and clean with acetone prior to applying 2K/M. Mixing: (SEE LAST PAGE FOR STEP-BY-STEP ILLUSTRATION) Mixing ratio by volume: ~5:3 (powder to liquid) • Pigmenting: When using liquid pigments with AQUAFIN-2K/M White, add and mix the liquid pigments with liquid Component-B prior to mixing Component-A with Component-B. • Pour 2/3 liquid Component-B into a clean container, add 2K/M powder (Comp-A) and mix to a lump free creamy consistency. Add remaining 1/3 liquid and mix total 2 - 3 minutes with a strong, slow speed (300 rpm) mechanical mixer. NOTE: In hot weather conditions water can be added after initial mixing to adjust application consistency as follows: max. 10 fl. oz. (0.3 L) per 46 lb (21 kg) unit Application: NOTE: Do not apply 2K/M at temperatures below 40°F (5°C) or to frozen substrates. Can be applied to 3 day old concrete at >86°F (>30°C) temperature and 5 day old at 60-70°F (15-21°C), or when concrete reaches minimum 2,000 psi (13.8 MPa). • Application tools: 2K/M may be applied by brush, roller, trowel or appropriate compressed-air spray equipment. Do not pre-dampen brush or roller with water. • Negative Side Waterproofing: AQUAFIN-2K/M is not resistant to negative side water pressure. Substrates prone to negative side water infiltration must be treated with a product designed to resist negative side water pressure, such as AQUAFIN-1K, prior to installation of AQUAFIN2K/M. • Static cracks: Repair static (non-moving) cracks with AQUAFIN CRACK SEALING TAPE (80% elongation), or rout (cut) out and fill with MORTAR-V/O and cover with 2K/M. • Dynamic cracks: Seal dynamic (moving) cracks with JOINT SEALING TAPE-2000-S (600% elongation). • Horizontal and vertical control joints: Seal horizontal wall-floor joints and internal vertical corners with JOINT SEALING TAPE 2000-S. Alternative: form cove (minimum 1.5“ x 1.5“ [38 x 38 mm] with MORTAR-LN or MORTAR-V/O. • Expansion joints: Seal non-traffic bearing expansion joints with JOINT SEALING TAPE-2000-S. Note: 2K/M applied over all tapes in visible areas will crack over the tape due to substrate movement. However, the tape and the structure will still be waterproof. Therefore, wherever aesthetics are important (i.e. walkways, decks, patios, etc.) honor all joints & cracks with an appropriate elastomeric joint sealant or pre-manufactured joint profile. • Construction & Movement joints under Tile: Ensure that construction and movement joints in tiles or stones are foreseen as per industry standards such as per ANSI specification A108.01-3.7 “Requirements for Movement Joints: Preparations by Other Trades” or TCNA detail EJ-171 “Movement Joints-Vertical & Horizontal”. • PVC pipe penetrations & stainless steel flanges: Abrade (sand) PVC pipes and stainless steel flanges and degrease with isopropanol or acetone. Apply 2K/M and embed SEALING GASKET-18/18 or JOINT SEALING TAPE-2000-S as per TDS. • Alkali sensitive substrates: Protect and seal alkali sensitive metal Check our website for the latest version of the Technical Data Sheet. www.aquafin.net

substrates such as copper, aluminum, galvanized or zinc treated metal first with a primer (i.e. KRYLON Primer, or equal) prior to applying (overcoating) 2K/M. • Reinforcement Mesh: Contact Aquafin Technical Department. • Protect areas not to be treated from 2K/M. Hardened 2K/M can only be removed mechanically. Applications: 1. Standard Application: Apply 2K/M in two coats as specified. High ambient temperatures can create flash setting when product leaves the Page 2 of 4
AQUAFIN®-2K/M spray nozzle, creating pinholes in the applied layer. If applied in full sunshine product can skin-up on the surface and de-bond, resulting in post-bubbling. •A pply 1st coat by brush to force material into the substrate. • Apply 2nd coat (or multiple coats) as soon as the 1st coat has sufficiently hardened (approx. 4–6 hrs @ 68°F (20°C)/63% RH) or max. 24 hours. Do not pre-dampen 1st or following coats. (If longer than 24 hours, 2KM surface must be prepared by high pressure water blasting or sanding/roughening and allowed to dry). Apply by brush, roller, trowel or appropriate compressed-air spray equipment. If sprayed, even out and seal surface by back-troweling, brushing, rolling to achieve a void-free membrane. • Thickness: 60 mils = 2x30 mils (2x0.8 mm) 80 mils = 2x40 mils (2x1.0 mm) 90 mils = 2x45 mils (2x1.1 mm). 2. CMU Block Substrates, 120 mils [1/8”] (3.2 mm): • Apply 2K/M in two coats at total 60 mils (1/16” (1.6 mm)) thickness as per item 1. 3. Potable Potable water holding tanks. Can be carefully filled after 7 days. Do not fill large tanks faster than 6½ feet per 24 hrs. (2 m/24 hrs). 4. Marine aquarium and zoo tanks: • Structure coat containing waterproofing admixtures: verify with admixture manufacturer that cementitious top coatings will bond to the concrete surface prior to installation of 2K/M. Aquafin recommends AQUAFIN-IC-ADMIX (liquid or powder). • Overlaying texture coat: Let 2K/M cure for at least 3—5 days before applying texture coat. Ensure that proper measures are taken to avoid shrinkage of the overlaying “texture coat”. Internal stresses of shrinking “texture coat” can negatively affect the bond to 2K/M, or the integrity of the 2K/M. Exposure(at 68°F {20°C} and 60% humidity) of Application to: • Rain: vertical surfaces after ~3 hrs, horizontal surfaces min. 6 hrs. • Foot traffic: after ~24 hrs. • Flexible tile mortar and tiles: after ~1 day. • Positive side hydrostatic pressure: after 2K/M reaches min. Shore A Hardness 80, check with “finger-nail test”. Typically 3–7 days • Back filling: after ~3 days. Sealing & Protecting: • Clear sealer: In areas such as walkways, balconies, etc. where higher than usual surface contamination can be expected, the surface of 2K/M can be sealed with a clear acrylic sealer. The 2K/M should be cured for min. 24 hrs. before applying sealer. • Painting: Cured 2K/M can be painted with a water-based, “breathable” acrylic paint after 3 days (at 68°F (20° C).
