Q: We have a 30 year old cabin in the mountains. It has Cypress floors installed with up to a 1/2″ gap between each length wise. I am assuming this is because there is no HVAC and temps inside may vary between ~20 deg and 80 deg F. Problem is in the kitchen where food and liquid can spill I’d like to seal the gaps.
Should I, and if so how?
A: There are companies that make chinking and sealant products for log cabins. I would explore those to see if they have a caulking that would meet your needs.
