5. Its perfect freedom from any of the caustic qualities of Lime Stuccoes; and consequently,

6. It may be painted upon as soon as dry, a property possessed by no other Cement whatever.

7. It is not in the slightest degree affected by frost.

8. It may be kept in the cask as delivered from the Manufactory for any length of time without deterioration, not requiring to be used (as other Cements are) immediately after being manufactured. To Merchants, therefore, and Exporters, even to the remotest parts of the globe, this Cement will form a most important item of commerce.

9. To Engineers and Conductors of Public Works, the use of this Cement is strongly recommended in lieu of mortar, particularly in the construction of Railway Arches and Tunnelling; its peculiarly tenacious property forming one hardened mass with the brick or masonry, or with whatever material it may be used; and it will be found particularly valuable in laying and pointing roofs, whether of slate or tile, in the most exposed situations, rendering the whole roof fixed and immoveable.

This Cement is sold in a fluid state, fit for its mixture with the sand, at 14s. per cwt.: the proportions being one fourth-part of the fluid to three-fourths of sand, thereby reducing the price of this Cement considerably below that of any other yet offered to the public.

One coat of the Cement, so prepared, is sufficient to cover at once a Brick Front, without any preparatory coat of lime, seven pounds of the fluid Cement being consumed in covering the square yard; but when laid on Lime Plaster, four pounds’ weight to the square yard will be found enough.
