Using or not using a concrete overlay product for the top layer of
a floor for thermal mass, vs. a plain darkly stained concrete slab
</blockquote>
<br>
A concrete overlay product is likely to be roughly similar in
thermal characteristics to a concrete slab. Meaning that you will
just have a thicker thermal mass. It seems unlikely that you should
be worried about <i>too much</i> thermal mass in a passive solar
house. The overlay product might have a lower specific heat, or
conductivity, wither of which will reduce it's effectiveness
somewhat. Remember to stick with a dark color.<br>
