1K putty
1K putty that is ready to use
1K putty is a ready-to-use putty that consists of one component and therefore does not need to be mixed with a hardener. This makes a one-component putty particularly easy to use and ideal for quick repairs. 1K putty is mainly used for filling small damages such as sanding scratches, pores, small cracks, and light dents. Thanks to its fine structure, this putty is also called fine putty, lacquer putty, or pore filler. The filler dries quickly in the air and can then be sanded very easily. This creates a smooth and even surface that is immediately ready for primer, lacquer, or paint. At CROP, as a specialist, you will find an extensive range of 1K putties for both professional use and do-it-yourself repairs.
When do you use 1K putty?
1K putty is mainly used for small repairs and fine finishing of surfaces. Think of filling small damages that are still visible after sanding or puttying with a coarser putty. Thanks to the fine structure, you can make a surface perfectly smooth before you start lacquering or painting. This putty is widely used in car damage repair, wood repairs, and lacquer preparation. For example, to fill small sanding scratches in car paint or micro holes in a puttied surface. Because 1K putty dries quickly and is easy to process, it is ideal when you want to quickly move on to the next step, such as sanding, priming, or lacquering.
Difference between 1K and 2K putty
The biggest difference between 1K putty and 2K putty lies in the composition and application. 1K putty consists of one component and is immediately ready to use. You do not need to add a hardener. The putty dries by contact with air and is especially suitable for small repairs and fine finishing. 2K putty consists of two components: a base putty and a hardener. These must be mixed first before you can use the product. This chemical reaction creates a putty with much higher filling power, stronger adhesion, and greater durability. Therefore, 2K putty is usually used for larger damages or deeper repairs.
The benefits of 1K putty
A 1K putty has several advantages that make the product popular among both professionals and hobbyists. Especially when you want to repair small damages or make a surface perfectly smooth, this putty is an excellent choice. Because one-component putty is immediately ready to use, you save time and prevent mistakes when mixing hardeners. Additionally, this putty has a fine structure which means you need to sand less and achieve a smoother final result faster. The main advantages of 1K putty are:
- Ready-to-use product: You do not need to add a hardener. This allows you to start puttying immediately.
- Quick-drying putty: 1K putty dries quickly in the air, allowing you to sand often within a short time.
- Perfect for fine finishing: Thanks to the fine structure, you can easily fill small pores, scratches, and micro holes.
- Easy to sand: The putty can be sanded very smoothly after drying.
- Flexible and elastic: After curing, the putty remains slightly flexible, preventing cracks.
Is lacquer putty the same as 1K putty?
Lacquer putty is often seen as a type of 1K putty, but the terms are not always used exactly the same. In practice, lacquer putty is usually a fine putty based on one component that is specifically intended for leveling small lacquer damages. Lacquer putty is used in the final phase of a repair, before the lacquer is applied. It fills small pores, sanding scratches, and micro holes that are still visible after puttying. Because lacquer putty is very fine in structure, a mirror-smooth surface is created on which lacquer adheres perfectly. In short: almost all lacquer putties are 1K putties, but not every 1K putty is specifically used as lacquer putty.
How do you best use 1K putty?
To achieve the best result, it is important that you apply 1K putty in the right way. With the correct method, you ensure a smooth and professional final result. Preferably follow this step-by-step plan:
- Clean and degrease the surface so that dirt and grease are removed.
- Sand the surface lightly for better adhesion of the putty.
- Apply a small amount of putty with a putty knife or spatula.
- Spread the putty thinly and evenly over the damage.
- Let the putty dry according to the indicated drying time.
- Sand the surface smooth with fine sandpaper until it is completely even.
After these steps, the surface is ready for primer, lacquer, or paint.
