A common issue is product damage occurring during transit and installation. Hemp Shield may be touched up over itself at any time. If they are using a color, the area where touch up is applied may appear darker and will need to be feather in. Not an issue with the clear. A second coat of Hemp Shield is not an issue (interior) with the “clear” as far as performance. However, a second coat may result in slightly higher gloss due to higher solids applied.
The reason we do not recommend a second coat of Hemp Shield for exterior is two-fold:
1) The formula for Hemp Shield contains some wax emulsions. While it is re-coatable when exposed to severe weather there may be a separation between coats.
2) The solids in a single coat are more than sufficient to protect the wood long term. A second coat is usually a waste of money.
