The screed thickness should not be less than 50mm.
Floor screed minimum thickness with sbr.
When bonding directly to the substrate with a bonding agent or a primer the minimum is 1 2mm feather edge with smoothing compound.
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.
However bs 8204 1 emphasizes that there is a high risk of screed curling with unbonded and floating levelling screeds.
Therefore to allow for deviations in the finished levels the specified design thickness should be a minimum of 70mm.
Bonded screed minimum depth.
If we look at each different type you re going to have different floor screed thickness on the minimum and maximum depths.
Floors and flooring bre 2003.
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.
Sbr polymer modified screed includes a synthetic polymer resin to give increased toughness and bond properties.
Also where bonded screeds are installed as part of a flexible waterproofing system in combination with a flexible bonding agents.
As 3958 1 2007 a2 3 a nominates the minimum bonded screed thickness of 15mm at any isolated point.
Pye pw and harrison hw.
There are proprietary screeds available that can be laid at thinner depths than conventional sand and cement screeds.
