But mix with mixing paddles in a drill and pour onto the damaged surface. Using a squeegee, spread out the screed over the surface. One time applied, finish with a specialist roller to achieve the required cease. When rolling, make certain that this is performed in the aforementioned management – unless of course a specific pattern is required.Should a slip resistant surface be required, expect until the screed is 'tacking off' and the pull the roller over the screed again.  You tin then achieve a 'ridged' finish which can provide an first-class, potent and very effective sideslip resistant finish, excellent for ramps, sloping areas, disabled entrances/areas/ etc.
