Cold Galvanizing Coatings Buyer’s Guide
There are so hundreds of home improvement and paint brands out there that have begun manufacturing cold galvanizing coatings. For this reason, one might find it especially confusing to zero in on one brand and purchase a product accordingly. To help you out with this process, after testing our 12 paints we have compiled a comprehensive buyer’s guide listing all the factors that you need to consider before purchasing this product.
So, without wasting any more time let’s jump right into it!
Type Of Paint
The two different types of galvanizing paint are mainly based on the way they have been packaged. One kind is packaged in a spray can while the other is packaged in a tin can.
Usually, the spray can variant is the more popular choice because of how easy it is to use and the even and smooth film it forms on all metal surfaces. However, the drawback to this type of paint is that it’s available in very limited volumes and usually tends to be expensive.
Alternatively, galvanizing paint packaged in paint cans is ideal if you are looking to use a lot of paint. Since they are available in larger volumes they are also comparatively cheaper as well. This paint, however, usually needs to be applied via paint brushes that don’t always provide a smooth finish on metal surfaces.
Current Condition of Project
The type of project one is planning to coat is a very crucial factor in determining the kind of galvanizing paint you should purchase. If your metal object is something that belongs to the exterior of the house, you will want to purchase a more high-performing and long-lasting paint.
Similarly, if you’re planning to galvanize a bare metal surface from scratch then you will need a very effective galvanizing paint with higher coverage. Alternatively, if you’re just planning to touch up an already galvanized surface then it’s wise to buy a galvanizing paint that is meant specifically for that function.
Different brands of galvanizing paints can withstand varying degrees of high temperature which is especially crucial to consider if you’re planning to paint pipes. Hence, it’s very important to check the highest temperature a particular cold galvanizing paint can withstand. This ensures that your metal surface remains secure and protected even under high-temperature circumstances.
People usually have different paint application methods that they are comfortable with. However, not all cold galvanization paints can be applied via all these methods. Most commonly, galvanizing compounds are packaged in spray bottles giving users no other option for the application method. Nevertheless, certain paints that come packaged in tin cans might be ideal for anyone planning to apply this paint via roller, brush, or even a pre-owned spray gun.
With that, we come to the end of our comprehensive guide. If you’re enthusiastic about home improvement or simply invested in prolonging the life of home equipment, then cold galvanizing paint is an irreplaceable addition to your arsenal.
Before we leave you to decide, we wanted to mention some of our favorite galvanizing paints from our testing session: Crown 7007G, for starters, is the perfect buy for anyone pursuing larger projects while looking for an effective hot-dipped galvanization performance.
Through our trial and error, we discovered that the CRC Zinc-It 18412, on the other hand, is the perfect paint for touch-ups that are high-powered and extremely quick drying! Alternatively, if you’re looking for a spray-can galvanizing paint that dries quickly but has a more glossy satin finish, then Rust-Oleum V2185838 is the one our research would indicate.
Now that we’re done with this, guess it’s time to leave you to it! We sincerely hope this article helped in making your decision just a little bit easier. Until next time!
