4 Ways to Enhance Flagstone Color to Darken:
Darkening flagstone has become a trend for people who want their pave ways, surfaces, or roofs to have a gorgeous black color. The exterior of your house brings the vibe of sophistication by the use of flagstone. Many people try to change the color of natural stone and paint to make it more appealing and striking at the same time.
However, darkening flagstone is not always a smooth job. You can adopt the following ways to darken it but they’ll come with their own malevolence along with benevolences. So, choose your way of enhancing flagstone color wisely.
a) Penetrating Sealer Additive:
Sealing is essentially important for flagstone. It’s because sealing can block the pores of flagstone. Also, a penetrating sealer saves the flagstone from tearing or spilling so easily. However, there are some penetrating sealers in the market that work for the color you want your flagstone to be.
These stone enhancers penetrate the stone and darken the color of the flagstone. Not all stone sealers come with the formula to darken flagstone. Some stone sealers have synthetic resin in them. And they are formulated to darken the stone over time. It can be found in any big home improvement store where you buy flagstone for your walkways or other patios.
b) Linseed Oil:
Linseed oil has a great traditional effect on making flagstone dark. Many people get confused if they should apply the raw or boiled linseed oil on the flagstone. However, you can apply both kinds of linseed oil. But raw linseed oil takes a hell of a time to be cured.
Therefore, boiled linseed oil is recommended by many professionals. It works tremendously in sealing pores and tiles. You can use linseed oil instead of using any sealant on your stones. But you may have to face some trouble while using this oil, as it can attract mildew. Besides, it requires a precise application to avoid the problems of excess oil on the surface.
c) Applying Heat:
Heat can be one of the fair ways to darken your flagstone floors. Using a blowtorch to accomplish the goal is a wise idea. However, this idea of heating flagstone goes right as long as you do this for the exterior beauty of your house. Otherwise, if you want to do this on your interior floor, a whole mess can happen.
Heating will darken flagstone but there is a chance that the sealer may get affected adversely. It will get melted if not taken care of enough. Besides, this heating application might cause unwanted accidents. Therefore, assistance from a professional is required for this application. In another way, you can apply the procedure right after you get off the sealer from flagstone.
d) Water-Based Stone Stain:
This might seem an artificial way to darken your flagstone but it’s totally worth it. Staining your flagstones black to bring back their same old glory only makes your exterior and interior look good. There’s nothing harm in it if you want to stain your flagstones black using water-based stone stain. But this is not a permanent solution as it will be faded over time again.
Though flagstone is a very reliable material to be the perfect and striking support for the floor like patios, driveways, and walkways, the aesthetic color of it can be faded in the exposure to the sun. However, staining flagstone requires some hardcore scrubbing with muriatic acid and it is quite laboring. It also requires some good attention to darken flagstone.
