Has anyone tried to seal a concrete floor with raw linseed oil? Does it work?

Question

New cement floor in garage. Lots of cement powder. Tried presure washer, hard & soft broom, not solving problem permenantly!!!! Need a solution to prevent the powder from forming on the floor please!!!

Answer 1

It sounds like an excellent plan - cheap and effective.

However, there are some considerations.

There might be unintended consequences or side effects - it might get smelly, or outrageously slippery, or attract vermin - you just don't know.

And the biggest problem of them all: Once applied, it's there to stay.

My advice: Consider a real concrete-sealer (does exist), or try a small piece of unused concrete to see what happens.

Answer 2

I hve to ask -- what are you trying to do?  Keep water vapor from coming into your basement?  Keep water from coming up?  Keep your garage floor less dusty?  Need to know your goal.

Answer 3

it'll probably attract flys

Answer 4

I had a concrete contractor who applied sealer whether you asked for it. The sealers designed for concrete are worth while. Old concrete needs to be thoroughly cleaned, rinsed, and dried.  

Answer 5

I would think this would be a messy way to seal the concrete. The oil will not completely dry, causing three potential problems: 1 - it will stick to your feet and be tracked to areas where you do not want it. 2 - it will be slippery and could cause falls. 3 - it will attract dirt and cause the floor to constantly look dirty.

You would be better off getting a sealer designed to work on concrete.

Answer 6

Linseed oil is a drying oil...containing linoliec acid. I have worked with linseed and perilla oil for many years and have spilled my fair share on the concrete floor. It sealed it up pretty good. Never thought of using it to completely seal the floor.
