Restoration Protocol: Mold / Mildew

Mold / Mildew Protocol

Mold is a moisture problem first and a stain problem second. The safe path is to control moisture, clean visible growth, dry completely, then address discoloration.
Mold and mildew summary

Problem Summary

Black spots or mildew on the floor surface. If the odor is strong, the wood is soft, or growth keeps returning, cosmetic repair should stop.

Step-by-step repair

Step 1 Inspect the moisture source

Step 1: Inspect the moisture source

Find and control hidden moisture or repeated dampness before any cleanup starts.

Checkpoint: the moisture source should be identified and controlled before the surface is treated.
Step 2 Remove the surface mildew

Step 2: Remove the surface mildew

Brush or clean loose growth carefully, then inspect whether the surface is actually improving.

Checkpoint: visible growth should be reduced without gouging the wood.
Step 3 Treat the discoloration

Step 3: Treat the discoloration

Use a verified treatment for the remaining stain and only repeat if the floor is still safe to treat.

Checkpoint: the discoloration should improve without making the wood look dry, bleached, or over-treated.
Step 4 Match the floor color

Step 4: Match the floor color

Once the area is clean and dry, use the ArtisanLabFix color matching workflow to reduce the visible stain.

Checkpoint: the dry sample should blend naturally with the surrounding floor.
Step 5 Restore and protect the finish if needed

Step 5: Restore and protect the finish if needed

Apply a thin compatible finish only after remediation is complete and the wood is fully dry and stable.

Checkpoint: the finish should cure evenly without odor, tacky spots, or sheen mismatch.

Do not paint or seal over active mold. If moisture or odor remains, the problem is bigger than a cosmetic repair.
