PVC panels require very minimal maintenance. While cleaning, it does not take long. Due to their smooth surface, dirt does not gather in the first place and simple wiping with cloth is sufficient for the necessary cleaning. However avoid usage of chlorinated agent or abrasive wiping cloth.
PVC paneling is highly resistant to moisture and water and does not warp, delaminate or swell in wet and humid conditions. Besides PVC paneling is better than wood paneling as regards to lower flammability.
For smooth surface no challenge, simple application with glue and nails shall work. However for uneven and rough surface either surface preparation to make the base even or making a frame marginally away from the surface and affixing the paneling on the frame thereafter shall take care of even for major surface unevenness.
