Eagle B181 High Performance Thin-Set Mortar Français
EAGLE B-181 is a high quality polymer modified universal thin-set mortar, that only needs water to install all types of natural stones and tiles on more demanding jobs. This thin-set is specially formulated for tiles, vitrified or not and also porcelain, either inside or outside, on horizontal or vertical surfaces. Having an excellent adhesion over conventional substrates, EAGLE B-181 gives very good adhesion over surfaces like asbestos or composite vinyl tiles, existing ceramic tiles, cement-based terrazzo, cut-back residues. Take note that rigorous attention must be taken to execute surface preparation conform to trade practices and Eagle Black’s surface preparation guidelines.
Surface Preparation
All surfaces shall be structurally sound, clean and free from traces of dust, oil, grease, wax, paint, acids, alkalis or any other materials that can reduce adhesion. The only recommended wood substrate for residential floors is an exterior grade plywood installed in an interior dry area. All concrete substrates shall be completely cured and at least 28 days old. It must also be free from hydrostatic conditions and/or extreme humidity problems. Remove all traces of paint, coating or loose particles. Ambient, surface and product temperature must be superior than 10ºC (50ºF)and lower than 35ºC (95ºF) during installation and for the first 24 hours.
Spread and scratch mortar on surface to be covered with flat edge of trowel. Quickly add mortar by using notched side of the trowel, spread mortar uniformly, taking care to trace ridge lines in the same straight line direction. Prepare the quantity that can be spread in less than about 15 minutes. If ridges have slightly dried and there is skin formation at the surface, there will be no adherence. The mortar will have to be removed and a fresh coat applied. Press tiles firmly with a back and forth motion across ridges to obtain full mortar transfer at the back of tiles at 1/3 of their thickness in mortar. Never wet tiles prior to their application, if so, it must be advised by tile manufacturer.
In a clean container, pour 250 ml of fresh clean water per kilogram of Eagle B-181. Add gradually powder while mixing with a low-speed drill and mixer. Blend for 1 to 2 minutes scraping recipient walls and paddle to obtain an homogeneous trowelable consistency. Let mortar sit for 10 minutes, than remix without adding any more water or powder. Apply immediately. Occasionally remix while using it, with no water addition.

Approximate coverage for a 22.7 kg (50lb) bag :
Trowel 6 X 6 X 6 mm (¼” X ¼” X ¼”) : 8.4 m² (90 ft²)
Trowel 6 X 10 X 6 mm (¼” X 3/8” X ¼”) : 6.0 m² (70 ft²)

Protect surfaces for 48 hours. Curing time may vary according to temperature and humidity level. Make sure application is dry prior to allow light traffic for grouting.
