For Coating Rough Walls

Mix one part of commercial water glass with three parts of water. Apply this with a brush. The lime in the mortar forms with water glass, silicate of lime and a coat-ing of glassy appearance results, solid, hard, and resistent to the action of the weather.

By painting whitewashed walls with water glass, the coating is rendered much more durable and will not rub off.

Zinc white 2 parts, and Paris white 1 part, mixed in water glass gives a beautiful white color.

Water glass is well adapted for painting metal, either alone or mixed with pigments.

Such a coating resists moisture and prevents rust or corrosion of the metal.

To each gallon of water glass, add 4 pounds of earth pigment and apply in the usual way. The addition of 1-4 pound of caseine, or 1-2 pound of dextrine to each gallon of water glass used, will render the coating more elastic and prevent scaling of the paint.

Wood is rendered fireproof by a simple coating of this substance.
