STRUCTURAL SUGGESTIONS 239<br />

Emulsified asphalt plastic is simply emulsified asphalt mixed<br />

by mechanical means in suitable proporti<strong>on</strong> with asbestos fibre<br />

and fine sand or other more suitable mineral aggregates, to<br />

form a plastic material resembling Portland cement mortar in<br />

c<strong>on</strong>sistency and suitability for applicati<strong>on</strong> with trowel over<br />

<strong>cork</strong>board surfaces. The advantage offered by a suitable<br />

emulsified asphalt plastic as a protective coating for <strong>cork</strong>board<br />

<str<strong>on</strong>g>insulati<strong>on</strong></str<strong>on</strong>g>, as compared with factory ir<strong>on</strong>ed-<strong>on</strong> mastic finish<br />

<strong>cork</strong>board, is found in the versatility of the plastic emulsi<strong>on</strong>.<br />

Except for the c<strong>on</strong>tingency of freezing weather, emulsified<br />

asphalt plastic may be applied <strong>on</strong> the job much like plaster,<br />

to any areas desired, at any time; and, furthermore, a suitable<br />

emulsified asphalt plastic may be applied so as to present a<br />

c<strong>on</strong>tinuous surface that is sufficiently elastic to withstand<br />

without cracking the c<strong>on</strong>tracti<strong>on</strong> and expansi<strong>on</strong> incident to<br />

cold storage rooms, while it may be difficult to have the joints<br />

between factory ir<strong>on</strong>ed-<strong>on</strong> mastic finish <strong>cork</strong>boards effectually<br />

sealed against the same forces. However, the factory ir<strong>on</strong>ed-<br />

<strong>on</strong> mastic joints can be properly sealed, under adequate super-<br />

visi<strong>on</strong> and with reas<strong>on</strong>able care.<br />

The choice between the factory finish and the plastic<br />

emulsi<strong>on</strong> should rest entirely up<strong>on</strong> all the facts surrounding<br />

each case.
