I had a deck built onto my home. I followed all the "rules" as to how long to let the wood "season" before applying stain.
I stained the hand rail and it looked perfect. I stained 3/4 of the deck floor and noticed that a very sticky sap was seaping ip through the stain. I called the stain company and they were stumped and told me to call Menard's where the wood was purchased. They too seemed perplexed so they sent out a representative to take a look.
Menard's said it was not their responsibilty and that I would have to contact Midwest Manufacturing since they were their supplier. The deck cannot be walked on at all due to sticky sap coming up through the wood. Midwest Manufacturing said that sap naturally occured in wood and that it would eventually go away.
The handrails, of the same wood are fine?! It has been 2 years and I still can't use my deck.
