Rinse the floor thoroughly then use a.
Dpm concrete floor. Which type of coating is chosen will depend on the intended use of the floor. Assuming that the damp proof membrane dpm under the concrete has failed in areas then yes you possibly would get the odd patch of dampness showing in the floor. It is preferable to cover the area being worked on with just one large sheet but in cases where more than one sheet is required joins should overlap by at least 150mm and be sealed to prevent any moisture coming up through the new concrete slab.
For deeper cleaning rent a rotary floor scrubber with and abrasive pad designed for concrete and use it to apply trisodium phosphate or tsp to the floor. Most damp proof floor coatings are applied directly to the concrete floor surface using a brush or roller. 1200 gauge dpms should be used when a floor is direct to the ground.
Thicknesses of dpms vary but 1 200 gauge is a common thickness. Beam and block floor detail damp proof membrane dpm concrete is not impervious to water and it is therefore necessary to protect the floor with a water resistant barrier to prevent moisture penetrating the building from the ground. Typically a dpm is a polyethylene sheet laid under a concrete slab to prevent the concrete from gaining moisture through capillary action.
Preparation is key with these coatings and the substrate must be sufficiently clean and dry. If there was no dpm i would suggest a uniformal distribution across the whole floor. A dpm damp proof membrane is a plastic sheet membrane that sits between a concrete slab or screed and acts as a barrier to stop moisture and contaminants entering a property from the ground.
The epoxy dpm comes as a two component system. A damp proof membrane dpm is used to create a barrier between a concrete or screed subfloor and the floor covering that is laid on top such as wood ceramic or quartz tiles laminate or carpet. A liquid epoxy damp proof membrane dpm is often used as a remedial solution where an existing dpm has failed or was never installed.
When can a dpm be installed. You should use them to protect all final floor finishes. The approved document suggests that a ground supported floor will meet these requirements if the ground is covered with dense concrete laid on a hardcore bed and a dpm is provided.
