Proper preparation prevents most problems. The surface to be treated must always be sound, dry, and free of dust and grease. Properly preparing the substrate ensures good adhesion of the product. If in doubt, always perform an adhesion test first and assess it after curing.

Wood: Remove any loose paint layers. Clean old, intact paint layers with LAB cleaner and rinse with clean water. Sand the surface thoroughly and remove all dust.

Clean bare wood, sand it, remove all dust, and finally prime it with LAB wood primer interior. Lightly sand between the primer and topcoat layers.

Other substrates such as plastic: First clean with a good degreaser (such as LAB cleaner), lightly sand if possible, and prime with LAB multiprimer. Lightly sand between the primer and topcoat layers.

LAB interior (interior lacquer) is a durable, solvent-free, water-based lacquer. This interior lacquer is available in 3 different sheen levels: matte, satin, and semi-gloss: 

1. Matte has a matte finish and a sheen level between 5-10% (depending on the color). 

2. Satin has a satin finish and a sheen level between 30-40% (depending on the color). 

3. Semi-gloss has a semi-gloss finish and a sheen level between 50-70% (depending on the color). 

Matte paint is popular these days, but it is slightly more porous and harder to clean than satin or semi-gloss. In general, the higher the sheen, the more durable the paint and the easier it is to clean. 

Choose the finish that best suits your preferences and how heavily it will be used:  

• Matte: a modern, sleek look, but harder to clean. 
• Satin: durable, easy to clean, and subtly glossy. 
• Semi-gloss: very durable and easy to clean, with an elegant sheen. 

Measure the length and width of the surface you’re going to treat. Multiply them together, then divide by the coverage per liter. Now you know how many liters you need for one coat.

For example: for a surface measuring 1 m x 2 m (2 m² : 11 m² = 0.2 liters), you’ll need 0.2 liters of LAB interior (interior paint) for one coat (based on coverage of 11 m² per liter).
