All data are average values obtained under laboratory conditions. In practical use temperature, humidity, and absorbency of the substrate may influence the above given values
• Not a vapor barrier, lets substrate “breathe” • Easy to use -- needs only to be mixed with water • Applied by glove pointing, trowel or low pressure air-spraying (guniting) • No odor -- No fumes -- Environmentally friendly Substrate Preparation: • All substrates must be strong, solid, stable, and of load bearing capacity. • Areas designated to receive repairs must remain structurally sound and stable during demolition and surface preparation work, and these conditions must continue throughout the course of the repair work. Any areas of concern or uncertainty should be discussed immediately with the site Superintendent and brought to the attention of the Engineer of record. • If water is accumulating from an active leak(s) through cracks or joints in masonry walls, concrete walls, or concrete floors, Aquafin recommends the process of injection grouting as a first step in stopping severe water intrusion. For more information about Aquafin’s extensive line of Injection Grouts, contact your local Aquafin Representative. • Leaking cracks and other minor leaks (with little to no water accumulation) can be plugged using MORTAR-LN. Refer to the current Page 1 of 4 (04/15/26-EK,AC)
MORTAR-LN MORTAR-LN Technical Data Sheet for preparation instructions and other important information. • Substrates must be clean and free from all potential bond breakers such as sand, dirt, dust, efflorescence and mineral deposits, grease, oil, previous coatings, paint, sealers, water repellants, curing compounds, etc. Mechanically clean the substrate to remove any bond-inhibiting substances and/or contaminants. • Mechanically prepare all surfaces (including new concrete and new masonry) to achieve a surface profile equal to CSP 5-7 as per ICRI Guideline No. 310.2R-13. Shot blasting, and hydro blasting (high pressure water-blasting at > 5,000 psi) are the preferred methods. • Properly clean mechanically profiled area(s) by hydro blasting (waterblasting) or thorough pressure washing. • Pre-water (thoroughly soak) the substrate extremely well with clean water. Pay particular attention to substrates with excessive absorption such as CMU-block walls and any substrate during hot/windy conditions. • All surfaces must be saturated surface dry (SSD), which is damp but with no standing water, immediately prior to the application of MORTAR-LN. In addition to general surface preparation requirements listed above, supplementary instructions for specific types of repairs and surface conditions are provided below: •B rick, CMU Block, Rubble Stone Walls, and Masonry Joints: • R epair any loose brick, CMU block, stone or rubble on masonry walls. • R emove cracked, damaged, and loose mortar from masonry joints. • R emove all dirt and debris from masonry joints with a brush or with compressed air. • F lush joints clean with water and leave damp. •N on-Leaking, Static Cracks and Static Cracks with Minor Leaks Exceeding 0.02” (0.4 mm): • R out out non-leaking, static (non-moving) cracks to a U-shaped configuration, appx. ¾” (19 mm) wide and a minimum of 1” (25 mm) deep. • R emove all dirt and debris from routed cracks with a brush or with compressed air. • F lush cracks clean with water and leave damp. •C oncrete Walls and Floors (including bug holes): •N ew concrete must be at least 5 days old, or concrete must have reached a minimum 2,500 psi (17.2 MPa) compressive strength. •M echanically remove all laitance, loose or deteriorated concrete by suitable means such as chipping hammer, chisel, sandblast, high pressure water blast (hydro blast) at greater than 5000 psi, or similar methods. • P repare minor surface voids and bug holes by using recommended mechanical preparation methods (shotblasting, hydro blasting, etc.) •C lean mechanically profiled area(s) by hydro blasting (waterblasting) or thorough pressure washing and leave damp. •D rilled Injection Grouting Holes and Tie Holes: • R emove dirt and debris from tie holes and drilled holes with a cylindrical bristle brush. • F lush holes clean with water and leave damp. •R eglet in Perimeter Joint or Wall-to-Ceiling Joint: •C ut a ¾ in. to 1½ in. (19 mm to 38 mm) deep by approximately 1 in. (25 mm) high horizontal groove into the concrete or masonry wall at the perimeter joint location and/or where the concrete or masonry wall meets the concrete ceiling. • R emove all dirt and debris from cavity with a brush or with compressed air. • Flush reglets clean with water and leave damp.
•R eglet in Corner Joint: •C ut a ¼ in. to ½ in. (6 mm to 12 mm) wide by ½ in. to ¾ in. (12 mm to 19 mm) deep vertical groove into the corner joints spanning the entire vertical length of the corner joints where two walls meet. • R emove all dirt and debris from cavity with a brush or with compressed air. • F lush reglets clean with water and leave damp. •S teel Pipes and Welds: •C lean steel pipe surfaces and welds to white steel. Jobsite Conditions & Preparation •O nly proceed with application when ambient and surface temperatures are above 40°F (4°C) and rising and below 90°F (32°C). •D o not apply MORTAR-LN when temperatures are expected to fall below 40°F (4°C) within 24 hours after placement. •D o not apply MORTAR-LN to frozen or frost covered concrete surfaces. • Do not apply MORTAR-LN when rain is expected within 6 hours after placement. • When applying MORTAR-LN in temperatures at or above 85°F (29°C), follow ACI hot-weather application guidelines to ensure a successful installation. Mixing Instructions: Read all instructions thoroughly prior to mixing and application. • Precondition MORTAR-LN to ~70°F (21°C) prior to mixing. • Use an accurate measuring container and always carefully measure the water amounts. For Each: Add: 50.0 lb (22.7 kg) bag
0.8 to 1.1 gal (3.0 to 4.2 L) of clean water
• Add the appropriate amount of potable water into a clean mixing bucket. Start with lowest water amount per mixing ratio. • Gradually add powder 1/3 at a time while mixing continuously. • For best results, mechanically mix at slow speed with a ¾” (19 mm) drill and “Jiffy” mixing paddle. Use a paddle type mortar mixer for large jobs. • Mix at slow speeds to prevent entraining air for a minimum of 3 minutes or until a lump-free consistency is achieved. • Add remaining amount of water, a little at a time, up to the highest water amount per mixing ratio if needed for workability. DO NOT OVERWATER! If too much water is added, the mixture tends to segregate resulting in uneven surface strengths. Surfaces with reduced strength must be removed mechanically. Note: Due to the MORTAR-LN hydrophobic characteristics, it takes up to 30 (thirty) seconds for mixing water to combine with the dry powder mix. Application Instructions: • Always apply MORTAR-LN over damp, SSD substrates. • MORTAR-LN may be applied using a flat trowel or using suitable mortar spray equipment such as gunite spray equipment or a peristaltic pump (i.e. Quikspray carrousel pump). • P arge Coats on Brick and Rubble Stone Walls: •M ix Aquafin MORTAR-LN with water to the consistency of a slurry and apply to the brick walls as a bond coat using a masonry brush. •W hile the bond coat of MORTAR-LN is still fresh/wet, apply a 1/8” to 1” (3 mm to 25 mm) thick parge coat of MORTAR-LN on the brick or rubble stone walls to fill in any missing mortar in the mortar joints and create a flush, even surface. • F or rubble stone walls, if there are still surface variations after the first parge coat, then finish MORTAR-LN with a rough texture while

MORTAR-LN still fresh in order to facilitate the bond for the next layer. Allow to cure until set (approx. 5 to 6 hrs.). Repeat the process as needed until the surface of the rubble stone wall is flush and even (dampen the surface of the underlying application of MORTAR-LN, apply a slurry bond coat of MORTAR-LN, apply another 1/8” to 1” (3 mm to 25 mm) thick parge coat of MORTAR-LN, and finish with a rough texture if an additional layer is needed). •H orizontal Concrete Repairs and Resurfacing: • P our MORTAR-LN in one working cycle at ¼” to 1” (6 mm to 25 mm) over horizontal surfaces, then compact and strike off. • Trowel-Applied Vertical/Overhead Concrete Repairs and Resurfacing: •M ix Aquafin MORTAR-LN with water to the consistency of a slurry and apply as a bond coat using a masonry brush. •W hile the bond coat is still fresh/wet, perform concrete patching, repairs, and resurfacing from 1/8” to 1” (3 mm to 25 mm) thick with MORTAR-LN and create a flush, even surface. • If multiple lifts are required, finish MORTAR-LN with a rough texture while still fresh in order to facilitate the bond for the next layer. Allow to cure until set (approx. 5 to 6 hrs.). Repeat the process; dampen the surface of the underlying application of MORTAR-LN, apply a slurry bond coat of MORTAR-LN, and perform repairs from 1/8” to 1” (3 mm to 25 mm) thick. • Spray-Application on Vertical/Overhead Concrete and Masonry: •S pray apply MORTAR-LN from 1/8” to 1” (3 mm to 25 mm) thick per lift. •M etal lath (stucco netting, diamond lath, chicken wire, etc.) can be used to facilitate placement of MORTAR-LN in vertical spray applications. • If multiple lifts are required, allow MORTAR-LN to cure until set (approx. 5 to 6 hrs.). Dampen the surface of MORTAR-LN and repeat spray application from 1/8” to 1” (3 mm to 25 mm) thick. • Patch and Fill Routed Static Cracks, Tie Holes, Drill Holes, Masonry Joints, Reglet Cavities, and Surface Voids: • F ill prepared cracks, holes, reglet cavities, and voids, flush to surface with MORTAR- LN. •C reate Triangular Cant/Cove in Perimeter Joints (Floor-to-Wall Joints), Corner Joints (Wall-to-Wall Joints) or Wall-to-Ceiling Joints: •U se MORTAR-LN to form a 2” x 2” (51 mm x 51 mm) or a 1.5” x 1.5” (38 mm x 38 mm) triangular cant/cove over perimeter joints where the concrete floor meets the concrete or masonry wall, and/or over corners where two concrete or masonry walls meet, and/or over the joint where the concrete or masonry wall meets the concrete ceiling. Finish & Top Coating: • Surface Finish: Final layer may be troweled smooth/flat, broomed to increase non-skid quality, or sprayed with orange peel texture. •C oncrete Joints: Re-establish all previously existing concrete joints within 2 hours of final set. • Top Coating with AQUAFIN-1K or AQUAFIN-2K/M: AQUAFIN-1K or AQUAFIN-2K/M can be applied as soon as MORTAR-LN has set (~5−6 hours). • Top Coating with Breathable Paint: Where specified or desired, MORTAR-LN can receive a breathable, water-based, acrylic paint. after 3 days. • Top Coating with Non-Breathable Paint or Coatings: Where specified or desired, MORTAR-LN can receive non-breathable, non-vapor permeable, paints or coatings (such as epoxy coatings) after 7 days. Note: MORTAR-LN does not function as a vapor barrier. If there is evidence of dampness coming through walls, contact Aquafin Technical Department for advice prior to specifying or applying moisture-sensitive coatings on walls. If there is evidence of a moisture vapor issue(s) Check our website for the latest version of the Technical Datasheet. www.aquafin.net
in the concrete floor slab, Aquafin recommends the application of a topical epoxy vapor barrier prior to the application of moisture-sensitive floor coatings. For more information about Aquafin’s Vaportight Coat products visit: www.vaportightcoat.com or contact your local Aquafin Representative. Protection: • Protect from freezing for 24 hours after application. Curing: • Standard Application with Top Coat of AQUAFIN®-1K or 2K/M: •D amp cure MORTAR-LN for approximately 5 to 6 hours, or until set. •A pply AQUAFIN®-1K or AQUAFIN®-2K/M over MORTAR-LN while it is still green. • Potable Water Applications to be left exposed (without AQUAFIN®1K or 2K/M as a Top Coat): • P otable water applications that will not receive AQUAFIN®-1K or AQUAFIN®-2K/M as a top coat, MORTAR-LN must be damp cured for at least 7 days. Begin curing as soon as MORTAR-LN has set by keeping surface moist as per ACI recommendations for Portland cement concrete, using wet burlap, polyethylene or a fine mist of water. Note: Higher temperatures will reduce the curing time. Clean-up: • Thoroughly clean all tools and other equipment with water prior to the material reaching final set. • Cured material must be mechanically removed. Limitations: • Curing times and set times are approximate and will vary depending on ambient (air) temperature, mix water temperature, the temperature of MORTAR-LN dry powder in the packaging, surface temperature of host concrete or host masonry, profile of the host concrete or host masonry, and the application thickness. • Do not add sand, aggregate, cement or other ingredients to the mix. • Do not add accelerators, retarders or admixtures to the mix. • Do not featheredge or apply MORTAR-LN less than 1/8” (3 mm) thick. • Do not exceed the maximum 1” (25 mm) thickness per lift. • Do not use MORTAR-LN in swimming pools, water falls in swimming pools, hot tubs, or fountains. •M ORTAR-LN is not recommended for filling concrete joints (cold joints, construction joints, contraction joints, expansion joints, etc.). Always reestablish movement joints when using MORTAR-LN. • MORTAR-LN is not recommended for application over hollow terracotta masonry (old structural clay tile). • Do not re-temper or use additional water during the finishing process. The addition of excess water will negatively affect the material’s final properties and appearance. • Like all cementitious products, variations in temperature, humidity, substrate moisture, air movement, application methods, and finishing techniques, will contribute to the end look of the finished product. Consistency in areas mentioned above typically yield a relatively uniform result. However, color uniformity of MORTAR-LN is not guaranteed. • Do not use MORTAR-LN as a structural repair mortar. If structural repairs are needed, consult a licensed Engineer and ask an Aquafin Representative about Aquafin structural repair products such as MORTAR-40 CI. • In exterior applications, MORTAR-LN must be finished with a paint or Page 3 of 4 (04/15/26-EK,AC)
