A liquid water-based solution for application of temporary floor markings on a polyurethane coated floor and a method of applying the same is disclosed. According to one aspect, the solution comprises 5-15% by weight of an acrylic copolymer, 1%-2% propylene glycol, 0.5%-2% dipropylene glycol mono-methyl-ether, 2-8% of titanium dioxide; and 1-5% of ethelyne glycol. The solution is dispensable through a foam applicator so that it can be used to form temporary lines for recreational and athletic activities. The solution has a drying time when applied to the polyurethane floor of under five minutes and can remains water soluble for an extended period of time so that it can be removed without damaging the underlying surface.

The present invention provides a foaming agent composition for civil engineering-construction materials containing an anionic surfactant (A), a surfactant aid (B) and a water-insoluble or slightly water-soluble nonionic surfactant (C).

A bulk dry cement may comprise a cement; a solid particle; and a liquid resin accelerator, wherein the liquid resin accelerator is disposed on a surface of the solid particle.

Various cement-containing compositions are disclosed, to be made into forms, and prefabricated building materials produced from cement-containing compositions with insulating properties. Some of the preferred embodiments include expanded polystyrene and an acrylic component to provide enhanced insulating properties, or have a lower density, lighter weight, and increased insulating R-value in comparison with other cement-containing compositions.
