On any surface one should be looking to apply a uniform thickness of lime render of about 9-12 mm (plasters being the top coat are applied much thinner, 4-7 mm).Click to see full answer. Similarly, you may ask, how thick should render coats be?The normal thickness is between 3 and 5 mm. On soft or weak background use 1:2 or 2:5. Successive coats must be weaker than this coat. The thickness of the first coat depends on the nature of the background and the overall thickness required of the render.Secondly, what is the mix for lime render? Traditional lime mortar is a combination of lime putty and aggregate (usually sand). A typical modern lime mortar mix would be 1 part lime putty to 3 parts washed, well graded, sharp sand. Other materials have been used as aggregate instead of sand. Also, should I use lime in Render? Lime Renders Can Assist Drying Out By Evaporation Dense renders used in conjunction with softer materials or on weaker backgrounds can cause serious problems by creating local stresses. High calcium lime renders allow evaporation and reduce the risk of trapped moisture and decay.How long does lime render last?With the modern acrylic or plastic-based renders, expect a job to last from anywhere between 20 to 40 years. This can depend on the smoothness of the job and how clean the walls were prior to its application.
