SPS Primary is a high-tech diffusion barrier specifically designed to stop the outgassing from PCB-containing surfaces. SPS Primary has undergone rigorous testing, and its effectiveness is well documented. Tests conducted at Roskilde University and Danish Environmental Analysis show that TWO SPS can reduce the outgassing from a PCB-containing surface by over 95% over a period of more than 10 years. SPS Primary is the most environmentally friendly PCB sealer on the market and contains no epoxy, isocyanates, or solvents. Therefore, SPS Primary can be used by all professionals and does not require any special courses or certifications. SPS Primary is touch-dry in just a few hours and cures in 24 hours, allowing work to continue after only 24 hours of curing time. This can include window installation, painting, sealing, etc. We always provide thorough instruction and guidance on the use of all our products. SPS Primary should be applied in at least two coats with 30-60 minutes between each coat. When a finished layer thickness of at least 150um has been achieved, the sealer should be left to cure for 24 hours. Note: Layer thickness gauges are always included with the product.
Indicative coverage with 2 coats:
- On concrete 4 – 6 m2 per kg.
- On bricks: 2 – 3 m2 per kg
- Non-absorbent surfaces: 8 – 12 m2 per kg.
