Apply a second coat of plain paint. Add a topcoat once the first coat is fully dry. Using a sand-free coat of paint on walls or floors seals in the sand, extends the life of the paint job and provides a more even finish. When adding sand, finishing with a coat of clear floor sealant provides the same advantages as an extra coat of paint.

Media with small grain size slow the water movement and increase the chance of clogging. The effective size (D 10) and uniformity coefficient (Uc) are the principal characteristics of granular media treatment systems. The ideal sand media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm.
