Tigre NHL 3.5 is off-white or very light tan in color, and when mixed with sand, it creates a softer finish than the equivalent Lafarge NHL 3.5. It has great plasticity and workability with a strong adherence to surfaces. Tigre materials do firm up a bit faster than other NHL products we have used, so we tend to mix and use the materials rather than mix then and let them sit before use. They meet the same standards as all other approved NHL products and is ideal for exterior and interior plasters and grouts.
Tigre Natural Hydraulic Lime demonstrates high water vapor permeability while maintaining an impermeability to liquid water that allows surfaces plastered with Tigre mortars to “breathe.” This particular NHL has excellent hydraulic properties that favor working environments with high humidity such as basements or damp locations both indoors and out. Its remarkable plasticity coupled with enhanced adhesion reduces a tendency to crack and allows for both comfortable and effective working mortar. If excessive amounts of water are mixed with the mortar in order to be used in a grout bag, we saw shrinkage cracks. However, this can be mitigated by reducing the water content or increasing the lime-to-sand ratio. For example, we will use a 1:2 ratio to back-fill rubble stone walls.
We have used these materials in stucco and pointing and can say, without a doubt, we love Tigre and so will you! Check out Our Servicesto see how we can help in your mortar and/or plaster needs! If you’re looking for a whiter NHL, check out our
Cemento Natural Tigre is a small, family-owned business in the Catalon area of Spain. They have been producing natural lime and cement since 1945 and are now the only producers left in Spain. We recently visited the offices, quarries, and learned that the vertical kilns they operate have been running continuously since they were built over a century ago. Tigre’s products are high quality materials that we found makes matching to existing lime mortar very simple, especially in the northeast region of the U.S. We thoroughly enjoyed meeting this family that runs all aspects of Tigre daily business. This type of company allows us the opportunity to help keep the tradition alive. For more info on Tigre, check out their website!
