Polyurethane – How to get the perfect results?

There could be many applications both industrial as well as personal where polyurethane is largely used as a sealant. For example, last month I took up the task of redoing my old floor. After replacing the old oak timber floor boards, I stuck around the issue of sealing. Then one of my friends suggested me with polyurethane which is now considered as an environment-friendly alternative to conventional sealants.

Earlier there was a misconception that polyurethane tends to leave significant health hazards irrespective of the shine and finish it brings to the surface. But today people know how they can bring down these hazards down by taking few precautions.

If you’re using solvent-based polyurethane, you need to adhere to the following basic precautions:
1. Vacate the premises for at least 14 days.
2. Empty pantries and refrigerators. Solvent fumes taint foodstuffs-even packaged products.
3. Remove pets from premises.
4. Remove all indoor plants.
5. Remove all oil and water based paintings.

The decision to get back to the premises, including pets and plants, is entirely up to the owner. Solvent based finishes generally take 14 days to a month to fully cure. . In addition, you can keep the moisture scavenger away by joining the pieces together tightly.
