This is a very common question. If you visit your local DIY outlet, a lot of the floor varnishes on offer have a colour included, such as teak or oak. The only real advantage of this is basically time and convenience during application. The disadvantage is that, with each coat you apply, the colour changes and darkens. You are guessing what the final appearance will be. Most importantly, as a coloured varnish wears with time and traffic, the colour starts to be affected immediately. With our process, the seal is protecting both the wood and the colour stain, ensuring that the stain remains consistent for far, far longer.
