Floor screed minimum thickness with sbr.

This screed provides high performance at thinner sections and is ideal when normal thickness cannot be achieved. Also where bonded screeds are installed as part of a flexible waterproofing system in combination with a flexible bonding agents. The screed thickness should not be less than 50mm. Isopol sbr a styrene butadiene sbr polymer latex screed additive and bonding agent for heavy duty flooring or rapid drying levelling screeds to receive various types of floor finishes.

As 3958 1 2007 a2 3 a nominates the minimum bonded screed thickness of 15mm at any isolated point. Isocrete isopol sbr is used to produce polymer modified wearing screeds for heavy duty and industrial flooring and for rapid drying levelling screeds. A minimum thickness of 65mm is possible provided the thermal insulation boards are firm enough for the compaction of the screed. Bonded screed minimum depth.

Therefore to allow for deviations in the finished levels the specified design thickness should be a minimum of 70mm. Floors and flooring bre 2003. Shrinkage and cracking is minimised permeability is reduced and flexural strength is improved. Bonded screeds are utilised where screed thickness cannot be built up or to minimise dead loads on structure.

When bonding directly to the substrate with a bonding agent or a primer the minimum is 1 2mm feather edge with smoothing compound. If we look at each different type you re going to have different floor screed thickness on the minimum and maximum depths.
