Will Deck Stain Kill Grass? 5/5 (1)

Do Deck Stains Harm Grass?

Absolutely! It is very important to avoid getting your exterior wood and deck stain on your grass when applying. This can easily be avoided by using poly tarps and plastic sheeting to cover the grass and capture any overspray or drips when applying your deck stain. It is very important that you remove the plastic tarps as soon as possible when you are done! Covering grass for more than 30-60 minutes on a hot day can create immense heat under the tarps and “burn” the grass.

Key takeaways
  • Deck stain will kill grass if it makes contact during application, so protection is essential before you begin.
  • Use poly tarps or plastic sheeting to cover grass and catch any overspray or drips during application.
  • Remove tarps immediately after finishing, do not leave them on grass longer than necessary.
  • Leaving tarps down for more than 30 to 60 minutes on a hot day can trap heat and burn your grass.
