Is water slicking of the finished lining surface permitted?

The prohibition of water slicking on the finished lining surface is rooted in the principles of refractory installation and performance. Applying water to a finished surface can lead to several adverse effects. Firstly, moisture can weaken the bond of the refractory material, potentially compromising the integrity and durability of the lining. Additionally, water can cause issues during the curing process by introducing unwanted variables that may lead to inconsistent performance characteristics.

In many refractory applications, particularly those exposed to extreme thermal and mechanical conditions, maintaining a well-defined surface texture and stability is crucial for optimal performance. The practice of water slicking could result in a surface that does not meet the required specifications, thus impacting the overall effectiveness of the refractory lining in its intended application.

The other options imply varying levels of permissibility for water slicking under certain conditions or with specific materials, but such allowances are generally not supported due to the risks associated with moisture interference in a finished refractory lining. This helps underscore why the answer clearly states that water slicking is not permitted.
