Are you worried about getting stains on your slate—whether on the floor or countertop? One of slate's many excellent qualities is its self-cleaning nature with a little help from the elements and time—slate "breathes." If the area will be exposed to significant spills, such as from cooking in the kitchen, red wine toasts on the terrace, or greasy creams in the bathroom, we recommend sealing the area. Here’s how to seal slate. Slate will then have a shield against all types of stains. Liquids will bead on the surface, making them easy to wipe away.
You Will Need:
Choose the Type of Sealant We recommend using a clear sealant. There are sealants specifically for slate and other natural stones, such as those from Akemi.
Be aware that some products on the market have a color-enhancing effect that alters the natural appearance of the slate.
For the best results, it is important that the area to be sealed is free of stains and completely clean.
There are various stain removers for different types of stains, such as grease, rust, moss, red wine, etc. Check this guide for how to remove all types of stains.
Once the surface is 100% dry, it’s time to apply the sealant.
Apply the sealant to the surface and allow it to penetrate for 5–20 minutes, depending on the temperature.
Then wipe over with a cloth.
Feel free to repeat the process to ensure the surface is fully saturated.
It’s important to follow the manufacturer’s instructions.
Allow it to dry—check the manufacturer’s instructions for drying time.
The effect starts to take place within a few minutes, and full water-repellent effect is achieved after 2–3 hours. Most manufacturers then recommend a specified curing time before use.
