For indoor use it is essential that the Palma timber mat is seasoned first in an outdoor environment for a period of 2 weeks. Seasoning the Palma timber mat, simply means to leave it exposed to the outdoors, please make sure that it is not placed on any unsealed surfaces as the timber may leach and stain the floor. This is because given that the shower room is humid and is lacking sunlight, a newly unpacked teak piece may not be able to take that humidity right on. It is also a good practice to move the Palma timber mat outdoors every 3 months to remove it from an excessively humid environment and be exposed to the sunlight.
