Concrete Sealer Buying Guide
To keep the concrete features around your home in good condition for years to come, it’s important to seal them with the proper type of concrete sealer. If you’re unsure about which one to use, take a look at the information below.
Concrete Sealer Type
There are three main types of concrete sealers:
Acrylic Sealer
Acrylic provides solid protection at a reasonably inexpensive price point. For increased durability, you can blend acrylic-based concrete sealers with epoxy, silicone, or polyurethane.
Try to look for virgin or pure acrylic rather than styrene acrylic. The latter is known to develop a yellow color under direct sunlight.
Epoxy Sealer
环氧密封剂也称为聚氨酯密封剂,其成本比丙烯酸密封剂高。bob体育app苹果下载但是,优质的环氧密封剂不能提供持续一到三年的柔软效果,而是可以保护您的混凝土五到十年。尽管耐用,但它们限制了表面的渗透性,因为它们厚度很高。
Penetrating Sealer
特种树脂(例如硅酮,硅氧烷和硅烷)混合以形成一个密封剂,可穿透混凝土表面的深处。该化学屏障充当驱虫剂,可防止诸如油,霉菌和其他污染物等材料破坏混凝土。我们建议穿透污渍常见的密封剂,例如在混凝土车道或车库地板上。
Sealer Amount
Consider how much area you must cover and how many coats of sealer the job will require. The area a concrete sealer covers is typically measured in square feet. You can usually purchase concrete sealers in containers ranging from 1 quart to 5 gallons in size.
Packaging
Many sealers come in a bottle with a cap. On the other hand, heavy-duty, commercial-grade concrete sealers may come in a large bucket or barrel. Generally, smaller containers are easier to open and pour. You want to avoid accidentally spilling too much sealer in an area where it’s not needed.
Concrete Sealer Drying Time
Depending on the weather conditions, the average drying time for concrete sealers is about 2 hours. However, overcast weather or high humidity could extend the drying time to 3–4 hours.
室内应用
水基密封剂是室内混凝土表面的方法。这是因为它们不含那么多易燃的有效化学物质。但是,如果有适当的通风,您仍然可以在室内使用基于溶剂的丙烯酸密封剂。
Sealer Life Expectancy
The longevity of your concrete sealer is largely determined by how well it’s applied and maintained. Thick, premium sealers, such as epoxies and urethanes, generally outlast acrylic sealers by at least a few years.
How To Maintain Your Concrete Surfaces
使用高质量的混凝土密封剂很重要,但是当您照顾车道,露台,人行道,车库地板和其他混凝土表面时,这只是要采取的必要步骤之一。以下是清洁和维护房屋周围混凝土的其他一些技巧:HomeHome
- 使用高压清洗机:Pressure washing gives you the satisfaction of seeing built-up grime wash away instantly. If you don’t have apressure washer, you can rent one from a home improvement store or borrow one from a neighbor.
- Clean spills:Immediately address any food, oil, or other spills on your concrete surfaces. A good concrete sealer can only do so much, and the longer the spill sits on your concrete, the more likely it is to stain or seep in.
- 检查裂缝:Regularly inspect your concrete for any cracking or deterioration.
- Sweep debris:尽管扫地似乎没什么大不了的,但保持混凝土看起来尽可能好。当您进行院子工作时,请确保清除多余的碎屑。
FAQ About Concrete Sealers
Why should I seal my concrete?
Without sealant, new concrete is vulnerable to damage from water, salt, oil, sunlight, and more. While you don’t need to seal your concrete surfaces, they last longer when you do.
Is concrete sealer toxic?
Yes and no. Many modern concrete sealers are considered non-toxic, with no volatile organic compounds or a minimal amount.
However, all concrete sealers should be handled carefully because they contain other chemicals that could irritate your eyes, nose, skin, and throat.
How often should I reseal my concrete?
透彻的柔软,基于丙烯酸的混凝土密封剂的应用应持续1 - 3年。基于环氧树脂的混凝土密封剂通常持续更长的时间,通常在5 - 10年之间。您的混凝土区域受到多少磨损会影响必须重新密封的频率。
How do I know if I need to reseal my concrete?
Besides the passage of time itself, there are two telltale signs that it’s time to reseal your concrete:
- 密封剂的表面看起来刮擦,暗淡,肮脏或磨损,或者您会发现擦伤或剥落。
- Water no longer beads on the surface of the concrete.
