Epoxy Floor Membranes
These products can be a useful material for providing a membrane to the surface of the floor where an existing membrane has failed or is absent. However, there are a lot of details to address if the installation is to be successful.
Above Ground Floors
1. Skirting must be removed and the wall Damp Proof Course found.
2. The floor surface must be prepared by needle gun, scaffolding or enclosed grit blasting.
3. Stabilise salts. The formation of salt crystals is strong enough to puncture the epoxy coating.
4. Fill voids and cracks with a non shrink mortar.
5. Form a small floor to wall joint with a non shrink mortar.
6. Apply the Epoxy coating with a roller or brush. Normally three coats. Dry sad is cast into the final coat to help key floor screeds.
Choice of Epoxy
This must be able to be applied on to substrate, giving moisture readings of 90%.
If using Epoxy coatings to the floor, then it is essential that the floor is suitably reinforced and able to withstand water pressure should it come to bear. Check with a Structural Engineer before proceeding.
Once cured, Epoxy coatings are brittle. If the substrate cracks then the Epoxy will crack. If salt crsytals form they can break through the Epoxy and ;eave a pin hole so compromising the membrane.
