Trowel lubricant damage

The installation on the left was carried out in late November. The installation started in the bottom left corner of picture 1 which was close to the house and worked away from the house finishing top right.

The day time temperatures were around 10oC dropping to -1oC overnight. The following day in the finishing area the resin went white. The close up images in 2 and 3 show the two areas in greater detail. 

The reason the resin has gone white is because soapy water was used as a trowel lubricant. In the areas furthest from the house the low night time temperatures has slowed the curing process enabling the water to react with the isocyanate (hardener) causing a gassing action making the surface go white.

To prevent this happing a trowel lubricant with no water in should have been used. Using soapy water as a trowel lubricant will also dramatically reduce working times and can damage the surface as polyurethane resin use atmospheric moisture to cure.

To resolve the issue a thin roller coat of resin was applied in very dry conditions. Picture number 4 shows the surface where this has been applied as a comparison.
