sieving 1 to 2 mm aggregates, use a screen with mesh openings of mm (¼ of 1 mm). The screens are placed in the preweighed weigh boats to collect dust that passes through the screen during weighing and for capillary rewetting (Step 3). 3. Samples are capillary rewetted from underneath by adding MilliQ (or double distilled)

Any subsequent coats may compromise the slip resistance of the coating. Due to the manual distribution of the broadcast aggregate it can be difficult to obtain a uniform result across the entire coating.
