This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. We are looking for very low density of FC and each foam we are trying do not go as low. This time around I use 15 pounds of portland cement, about 8 and a half pounds of water, 3/4 of a pound of foam and a pinch of fiber. The more uniform the bubble size is the stronger the FC will be. Any home made agent tend to give a poor result! The gray paint makes the foam stiff and gives it a first shade of color. Hi The track has been embedded in concrete.

The rules for curing FC are the same as for normal concrete, go to https://www.wikihow.com/Cure-Concrete. sandpaper Re: foamboardvs posterboard. The mortar is a cement mix with sand and water.
