How to Apply 170 tb Primer on Different Substrates

To achieve the best results with 170 tb primer, you need to follow some steps to prepare the surface for priming, choose the right application method, and apply the primer on different substrates. Here are some tips and guidelines for each step:

How to Prepare the Surface for Priming

1.  The surface should be clean, dry, and free of dust, dirt, grease, oil, wax, or any other contaminants that can affect the adhesion or appearance of the primer.

2.  The surface should be sanded with 180-220 grit sandpaper to remove any previous finish or roughness. Sanding also creates a mechanical bond between the surface and the primer.

3.  The surface should be wiped with a tack cloth or a damp cloth to remove any sanding dust. Do not use mineral spirits or other solvents to wipe the surface, as they can react with the primer.

How to Choose the Right Application Method

– You can apply 170 tb primer with a brush, a roller, or a spray gun, depending on the size and shape of your project. Each method has its advantages and disadvantages, so you need to choose the one that suits your needs and preferences.

– A brush is suitable for small or intricate areas, such as edges, corners, or mouldings. A brush can also create a smooth and even finish, as you can control the amount and direction of the primer. However, a brush can also leave brush marks or streaks, especially if you use a low-quality brush or apply too much primer.

– A roller is suitable for large or flat areas, such as panels, doors, or cabinets. A roller can also create a fast and uniform finish, as you can cover a large surface area in a short time. However, a roller can also leave roller marks or bubbles, especially if you use a low-quality roller or apply too much primer.

– A spray gun is suitable for any size or shape of the project, as you can adjust the spray pattern and pressure to suit your needs. A spray gun can also create a flawless and professional finish, as you can avoid any marks or bubbles. However, a spray gun can also create overspray or waste, especially if you use too much primer or spray too close to the surface.
