A sealer is a protective coating that can be applied to the surface of a concrete planter to help prevent water and other liquids from penetrating the material.
By doing so, it helps to extend the life of the planter and keep it looking like new. There are many different types of sealers available, each with its own unique benefits and drawbacks.
When choosing the best sealer for concrete planters, there are a few critical things to consider. The first is the type of sealer. There are two main types: penetrating sealers and topical sealers.

The second thing to consider is the level of protection the sealer provides. Some sealers are designed to provide a high level of protection against water, stains, and other liquids, while others may only offer minimal protection.
The third factor to consider is the ease of application. Some sealers require multiple coats or special equipment to apply, while others can be applied with a simple brush or roller.

Buying Guide
When choosing a sealer for concrete planters, there are several factors to consider. Here are some key features to look for:
Type of Sealer
There are two main types of sealers for concrete planters: penetrating sealers and film-forming sealers. Penetrating sealers penetrate the surface of the concrete and provide long-lasting protection against water and other liquids.
Film-forming sealers sit on top of the concrete and create a protective layer that is more visible. Both types have their advantages and disadvantages, so it’s important to choose the one that best suits your needs.
VOC Content
Volatile organic compounds (VOCs) are chemicals that can be harmful to the environment and human health.
Some sealers contain high levels of VOCs, so it’s important to choose a product with low VOC content. Look for products that meet the VOC regulations in your area.
Durability
Concrete planters are exposed to harsh weather conditions and regular wear and tear, so it’s important to choose a sealer that is durable and long-lasting.
Look for products that are specifically designed for outdoor use and provide protection against UV rays, water, and stains.
Application Method
Some sealers require special equipment or professional application, while others can be applied with a brush or roller. Consider the application method when choosing a sealer to ensure that it is easy to apply and fits your skill level.
Cost
Sealers can vary greatly in price, so it’s important to consider your budget when choosing a product. Keep in mind that higher-priced sealers may offer better durability and protection, but may not always be necessary for your specific needs.
By considering these factors, you can choose the best sealer for your concrete planters that provides long-lasting protection and enhances their appearance.
