REMARKS
BONDFLEX 290 LM is very elastic while most paints are not. Therefore the painted surface may crack in joints with movement. Because of the diversity of paints available a compatibility test is recommended before application.
BONDFLEX 290 LM must not be applied to frost-bearing surfaces or if temperature will fall below freezing.
