There are 2 types of scratches: if it is a metallic scratch you can use undiluted DETERDEK and scrub with a scouring pad.
Deeper scratches, caused by the action of sands, cannot be removed.
How to make a floor plan:
With the help of a tape measure, measure the long side and the short side of your bathroom.
Create a simple drawing and write down the measures.
Also add structures: doors, windows and sanitary items.
If you want you can also add measures for doors and windows and their distance from the wall.
If you want to remove any sanitary ware please mark with an X.
The more information you add, more accurate your bathroom will be.
