Stain Proofing
There are two givens:
- The primary goal is to protect the underyling, surfacing. It is an expensive operation to remove and replace these materials, but not the sealer.
- You will spill things on the flooring.
Answer
Protect the surfacing with the appropriate sealer and "Lifeguard".
It would be an extreme situation to hurt Lifeguard and the Aldon sealer. If that were actually to happen - it is ok. Both are easily removed and replaced.
In the unlikely event that the "Lifeguard" coating were to stain, it is easily removed and replaced in that area. In the even more unlikely event that something actually penetrated the "Lifeguard" and stained the underlying sealer, it still isn't a catastrophe. The sealer is also easily removed and replaced in that area and the flooring has not been reached by the stain.
Acidic liquids like wine and fruit juices do not react with Lifeguard or the sealers. Therefore, if something were to actually get through these barriers it would have to be on the order of hot bacon grease allowed to sit for some time.
We are not aware of any product available that is truly stain proof. The underlying Aldon sealer is extremely stain resistant and so is the "Lifeguard" top coating. It would be wonderful if a sealer could be considered stain proof, but nobody truly makes one and it is a dangerous premise. All spills should be cleaned up immediately no matter your confidence in the surface.
