You may find yourself uncertain when deciding between polycrylic and polyurethane for your project.
Each option has its own set of qualities, and picking the right one means considering things like surface type, application, and the look you’re after.
Understanding Polycrylic
Polycrylic is a water-based sealer that protects surfaces like wood, metal, or concrete. You can find it as a liquid or spray, making it flexible for different types of projects.
It dries quickly, gives off less smell, and you only need soap and water to clean up.
Deciding How Many Layers of Polycrylic to Apply
You’ll usually need two or three coats, based on the level of use and exposure the surface will face.
More coats build stronger defense, especially for items that see heavy handling or are kept outdoors. Always let each layer dry completely before adding another.
Polycrylic Pricing Guide
The price you pay will depend on the product size and the brand you choose. Typically, you’ll spend between $10 and $30 per quart.
Special mixes or buying in bulk can affect the cost. Local store prices sometimes differ from online rates, and sales may further impact what you pay.
Benefits and Drawbacks of Polycrylic
Pros
- Minimal odor during use.
- Lower VOCs compared to alternatives.
- Cleanup with just water and soap.
- Keeps the wood’s natural color clear—no yellow tint as it ages.
- Best suited for cooler-toned stains or paints.
- Fast drying lets you finish projects quickly.
Cons
- Does not produce a warm, amber hue.
- Offers less resistance to scratches, water, and harsh chemicals than polyurethane.
What Is Polyurethane?
Polyurethane is a synthetic, protective coating often used on wood surfaces. You can find it in two main types: oil-based and water-based.
It forms a resilient layer that helps shield wood from moisture, chemicals, and daily wear.
How Many Layers of Polyurethane Should You Apply?
Applying two to three coats typically provides a solid level of protection. Oil-based polyurethane products often cover better with fewer coats, while water-based versions may need extra layers for similar durability.
Be sure to let each coat dry completely before moving to the next.
What Is the Price of Polyurethane?
Polyurethane prices vary based on type, brand, and container size. For example, a quart of polyurethane can cost around $16–$18 at many hardware stores.
Usually, water-based options are pricier upfront but may lead to higher long-term costs because they need more frequent reapplication.
| Type | Typical Price/Quart | Long-Term Cost |
|---|---|---|
| Oil-Based | Lower | Lower |
| Water-Based | Higher | Higher |
Advantages and Disadvantages of Polyurethane
Benefits:
- Offers great resistance to moisture, chemicals, and abrasion
- Simple to apply for most home projects
- Enhances warm-toned stains
Drawbacks:
- Oil-based versions may turn yellowish over time
- Not the best choice for cool-toned stains
- Can contain higher amounts of VOCs, especially oil-based
- Oil-based types are harder to clean and less eco-friendly
- Flammable, so handle with care
Polycrylic or Polyurethane: Picking the Right Finish
Which Finish Is Safer for Items That Touch Food?
Both polycrylic and polyurethane are not officially classified as food safe. However, after these finishes have fully cured, they are generally seen as non-toxic and safe enough for most projects.
If you want a finish for kitchenware or cutting boards, you’ll need to look for a product that is specifically labeled food safe.
Comparing Water Resistance: Which Keeps Moisture Out Best?
Both finishes offer some resistance to moisture, making them suitable for surfaces like furniture and cabinets that might get the occasional splash.
Neither option is completely waterproof. Water-based polycrylic and water-based polyurethane can break down quicker over time, especially in high-moisture areas.
Oil-based polyurethane typically holds up better against long-term exposure to water.
| Product | Water Resistance | Waterproof? |
|---|---|---|
| Polycrylic | Moderate | No |
| Water-based Polyurethane | Moderate | No |
| Oil-based Polyurethane | Strongest | No |
Comparing Costs: Which Option Is More Budget-Friendly?
There isn’t a major price difference between polycrylic and polyurethane. You’ll usually find them in the same price range, so cost shouldn’t be the deciding factor in most cases.
Instead, think about the type of surface you’re working with and how much durability you need.
Durability Showdown: Which Protective Finish Lasts the Longest?
Longevity can vary depending on the conditions your project faces. Oil-based polyurethane is known for lasting the longest, especially where moisture, heat, or frequent handling are concerns.
Polycrylic and water-based polyurethane are easier to apply and clean up, but may not hold up as well under tough conditions.
Is It Possible to Paint Over a Polycrylic or Polyurethane Finish?
You can apply paint over polycrylic or polyurethane, but careful surface prep is required.
Clean thoroughly and lightly sand the surface first to help the new layer stick. Keep in mind that these are topcoats, so results can vary, and some paints may not bond well.
Applying Polyurethane on Top of Polycrylic, or Polycrylic Over Polyurethane
It’s generally not recommended to layer polyurethane over polycrylic or put polycrylic on top of polyurethane.
Doing so may cause issues like poor adhesion, chemical reactions, or reduced durability over time. To avoid problems, stick with one type of finish for a single project.
Using Spray Methods for Polycrylic and Polyurethane
Both polycrylic and polyurethane can be sprayed, but caution is advised. While professionals might thin these products to spray them, for most DIY projects, the pre-made aerosol options are safer and easier to use.
This reduces the risk of uneven coats or clogging.
| Application Method | Recommended For DIY | Notes |
|---|---|---|
| Brushing | Yes | Most user-friendly |
| Pre-made Aerosol Spray | Yes | Good for smaller projects |
| Professional Sprayer | No (unless experienced) | Requires thinning and skill |
Safety Tips When Working With Polycrylic and Polyurethane
To protect yourself, work in a space with good airflow and use a respirator, especially with polyurethane.
Wear gloves and old clothing to prevent skin contact. Store all products away from children, and avoid using them near open flames or heat sources.
Safety Checklist:
- Work in ventilated areas
- Use protective gear
- Keep away from kids and heat
- Store in a cool, dry place
