Harwal Rigid Polyurethane Spray Foam Insulation

HP-SP-3040 is designed for processing on high and low pressure machines that are able to work at mixing ratios of 1:1 by volume. The machine parameters have to be selected in such a way to ensure proper mixing. 
The system should be spray-applied to substrates when ambient air and surface temperatures are between 10°C and 50°C. 
All substrates to be sprayed must be free of dirt, soil, grease, oil, and moisture prior to the application of HP Spray. 
Moisture in any form: excessive humidity (>85%R.H.), rain, fog, or ice will react chemically and adversely affect system performance and corresponding physical properties. 
Wind velocities in excess of 20 km per hour may result in excessive loss of exotherm and interfere with the mixing efficiency of the spray gun affecting foam surface texture, cure, physical properties, and will cause overspray. 
Precautions must be taken to prevent damage to adjacent areas from fugitive overspray.

How does moisture, such as excessive humidity or rain, affect the performance and physical properties of the HP-SP-3040 spray foam insulation?
it seems like you have provided the wrong text. However, to answer your question, moisture in any form, such as excessive humidity, rain, fog, or ice, will react chemically and adversely affect system performance and corresponding physical properties of the HP-SP-3040 spray foam insulation.

What wind velocities should be avoided to prevent interference with the mixing efficiency and foam surface texture of the HP-SP-3040 spray foam insulation?
The wind velocities in excess of 20 km per hour should be avoided to prevent interference with the mixing efficiency and foam surface texture of the HP-SP-3040 spray foam insulation.

What precautions should be taken to prevent damage to adjacent areas from fugitive overspray during the application of the HP-SP-3040 spray foam insulation?
To answer your question, precautions must be taken to prevent damage to adjacent areas from fugitive overspray during the application of the HP-SP-3040 spray foam insulation. 
Applicators should ensure the safety of the jobsite and construction personnel by posting appropriate signs warning that all "hot work" such as welding, soldering, and cutting with torches should take place no less than 35 feet from any exposed foam. 
If "hot work" must be performed, all spray polyurethane foam should be covered with an appropriate fire or welder's blanket, and a fire watch should be provided
