Do granite umbrella bases need to be sealed?

Hey there! As a supplier of granite umbrella bases, I often get asked this question: “Do granite umbrella bases need to be sealed?” Well, let's dig into this topic and find out.

First off, let's talk a bit about granite itself. Granite is a natural stone, formed deep within the Earth's crust over millions of years. It's known for being tough and durable, which is why it's a popular choice for all sorts of things, including umbrella bases. But just because it's tough doesn't mean it's invincible.

One of the main reasons people consider sealing granite umbrella bases is to protect them from stains. Granite is a porous material, which means it has tiny holes or pores on its surface. These pores can absorb liquids like water, oil, and even dirt. If you spill a glass of soda or some cooking oil on an unsealed granite umbrella base, there's a good chance it'll leave a stain. And once a stain sets in, it can be a real pain to get rid of.

Sealing the granite can help create a barrier on the surface, preventing liquids from seeping into the pores. This makes it much easier to clean up spills and keeps your umbrella base looking nice and new for longer. For example, if you have a Round Granite Umbrella Base, a good sealant can protect it from all those accidental spills that happen when you're enjoying a drink by the pool.

Another benefit of sealing is protection against weathering. If your umbrella base is outside all year round, it's going to be exposed to the elements. Rain, snow, and extreme temperatures can take a toll on the granite over time. Sealing can help reduce the effects of weathering by making the granite more resistant to water damage and freeze - thaw cycles. When water gets into the pores of the granite and then freezes, it expands, which can cause cracks and chips. A sealed granite base is less likely to suffer from this kind of damage.

Now, let's look at the other side of the coin. Some people might think that sealing isn't necessary. After all, granite is already a very hard and durable material. And in some cases, they're right. If your umbrella base is going to be used in a covered area, like a screened porch, where it won't be exposed to a lot of spills or harsh weather, sealing might not be a top priority.

Also, sealing granite can be a bit of a hassle. You have to clean the base thoroughly before applying the sealant, and then you need to wait for it to dry properly. And depending on the type of sealant, you might need to re - apply it every few years to maintain its effectiveness.

But here's the thing. Even if your umbrella base is in a protected area, it's still a good idea to seal it. You never know when an accidental spill might happen, and a little bit of prevention can go a long way.

When it comes to choosing a sealant for your granite umbrella base, there are a few things to keep in mind. There are two main types of sealants: penetrating sealants and topical sealants. Penetrating sealants soak into the pores of the granite and form a protective layer from the inside. They don't change the appearance of the granite much, and they're usually more durable. Topical sealants, on the other hand, form a layer on top of the granite. They can give the granite a shiny finish, but they might not be as long - lasting as penetrating sealants.

If you're not sure which type of sealant to use, you can always ask a professional. They can recommend the best sealant for your specific needs and the type of granite you have.
