If you’ve recently pressure washed your concrete surface, you may be wondering what’s next in the maintenance process. While pressure washing is an essential step in keeping your concrete clean, it’s not the final step. Applying a concrete sealer is a crucial follow-up task that many homeowners and property managers overlook. So, what happens if you don’t seal concrete after pressure washing?
The Importance of Sealing Concrete
Concrete sealing is a process that protects the concrete from damage caused by environmental elements, heavy foot traffic, and chemical spills. A concrete sealer creates an impermeable barrier that prevents water, dirt, and other substances from penetrating the concrete, causing damage and discoloration.
Without a sealer, concrete is exposed to the elements, making it prone to:
- Water damage: Water can seep into the concrete, causing cracks, erosion, and damage to the underlying structure.
- Staining: Dirt, oil, and other substances can leave unsightly stains on the concrete, reducing its aesthetic appeal.
- Erosion: Exposure to heavy rain, snow, and ice can cause the concrete to erode, leading to uneven surfaces and potholes.
The Effects of Not Sealing Concrete After Pressure Washing
Pressure washing is an effective way to clean concrete, but it can also have unintended consequences if not followed up with sealing. Here are some of the effects of not sealing concrete after pressure washing:
Dirt and Stains Re-Appearing Faster
Pressure washing removes dirt and stains from the surface of the concrete, but it doesn’t provide a long-term solution. Without a sealer, dirt and stains can reappear faster, as the concrete is still porous and susceptible to stains.
Etching and Pitting
The high-pressure spray used in pressure washing can cause etching or pitting on the concrete surface. Etching creates small, rough patches on the surface, while pitting creates small craters. Without a sealer, these imperfections can become more pronounced, making the concrete surface appear dull and rough.
Increased Risk of Freeze-Thaw Damage
In cold climates, water can seep into the concrete and freeze, causing the concrete to expand and contract. This freeze-thaw cycle can lead to cracking, spalling, and other forms of damage. Without a sealer, the concrete is more susceptible to freeze-thaw damage, which can lead to costly repairs.
Reduced Lifespan of the Concrete
The lifespan of concrete can be significantly shortened if it’s not sealed after pressure washing. Exposure to the elements, heavy traffic, and chemical spills can cause the concrete to deteriorate faster, leading to costly repairs or replacement.

What happens if I don’t seal my concrete after pressure washing?
Not sealing your concrete after pressure washing can lead to a host of problems. For one, the concrete will be more susceptible to stains and discoloration, as the pores of the concrete will be open and ready to absorb any substance that comes into contact with it. This can be particularly problematic if you have a driveway or sidewalk that is subject to heavy foot or vehicle traffic. Secondly, the lack of a sealant can cause the concrete to weaken and deteriorate over time, leading to cracks and other forms of damage.
All of these issues can be costly and time-consuming to repair, and can even lead to safety hazards if not addressed promptly. Furthermore, failing to seal your concrete after pressure washing can also lead to a loss of curb appeal, which can negatively impact the value of your property. In short, not sealing your concrete after pressure washing can have serious and far-reaching consequences that can affect both the appearance and integrity of your concrete surfaces.
Will my concrete turn yellow or become discolored if I don’t seal it?
Yes, it is highly likely that your concrete will turn yellow or become discolored if you don’t seal it after pressure washing. This discoloration can occur for a number of reasons, including the presence of dirt and debris, exposure to the elements, and the natural degradation of the concrete over time.
When concrete is not sealed, it can absorb substances like oil, grease, and other contaminants, which can cause discoloration and staining. Furthermore, the lack of a sealant can also cause the concrete to become more porous, allowing it to absorb more substances and leading to a greater likelihood of discoloration. This discoloration can be difficult and costly to remove, making it essential to apply a sealant to your concrete after pressure washing.
