SEALTIGHT MEADOW-PATCH T1 is a one-component, polymer-modified, cementitious resurfacing/repair mortar designed for horizontal, vertical and overhead applications. This all-purpose mortar is designed for patches, toppings and repairs from 1" thickness to featheredge.
MEADOW-PATCH T1 is easy to mix and apply; versatile and produces repaired surfaces suitable for rubber-wheeled traffic. For overhead or vertical use; MEADOW-PATCH T1 is an ideal choice for smoothing rough surfaces, repairing honeycombs and dressing up bugholes. When mixed, this creamy consistency provides an excellent skim coating for swimming pools, concrete walls, balconies, etc. Because of its excellent bond and freeze-thaw resistance, MEADOW-PATCH T1 may be used for interior and/or exterior; below, above or on grade.
MEADOW-PATCH T1 is available in 50 lb. (22.7kg) bags. When stored on pallets in a dry, cool area, it has a shelf life of 12 months.
Cement gray. MEADOW-PATCH T1 covers approximately 55 ft.² @ 1/8 in. (5m.² @ 3mm).
Do not apply MEADOW-PATCH T1 when the temperature is expected to be below 45ºF (7ºC) within 48 hours or when rain is imminent.
Maximum application thickness must not exceed 1" (25.4mm) neat. Avoid steel-wheeled traffic in thin applications. Thin applications subject to point loading should also be avoided. Protect thin applications from rapid water loss.
Mechanically abrade existing substrate to remove all unsound concrete, but do not use excessive force which may cause micro-fracturing. Prepare surface in accordance with ICRI Technical Guide No. 03730. Substrate must be structurally sound and free of grease, oil, dirt or any other contaminants that can adversely affect the bond. Prepared surface must be dust-free and have sufficient profile to ensure adequate mechanical lock. Substrate must be saturated, surface dry (SSD) and free of standing water.
For maximum bond, prime (SSD) substrate with slurry coat (two parts powder to one part SEALTIGHT ACRY-LOK). Allow slurry coat to become tacky prior to application of MEADOW-PATCH T1. Do not allow slurry coat to become tack free.
Using a mortar type mixer, add 3.0 quarts (2.8L) of clean water per 50 lb. (22.7kg) of MEADOW-PATCH T1. Slowly add powder and mix to desired consistency, using up to 0.5 (0.47L) additional quarts of clean water, as needed. Mix for 3 minutes, or until lump-free consistency is obtained. Do not over mix. For small repairs, mix in a clean vessel using a variable-speed drill with a paddle mixer at 400-600 rpm. Mix only complete bags. Do not mix more material than can be placed and finished in 30 minutes at 77ºF (25ºC).
Apply MEADOW-PATCH T1 into the repair zone substrate by compacting the material well against the properly prepared substrate. Finish surface with wood or sponge float. Never retemper.
The use of SEALTIGHT EVAPRE may proceed immediately after screeding and / or between finishing operations. MEADOW-PATCH T1 must be cured in accordance with ACI 308 utilizing a suitable curing compound such as SEALTIGHT 1100 Series, SEALTIGHT 1600 Series or VOCOMP-25. Protect from rapid early water loss.
