How to choose paint for renovation of old doors and windows

When we built the house, our windows were all made of wood, and it took a long time to paint the books, which was a bit old. So it needs to be renovated with paint. What methods are there in decoration and how to choose coatings? We don't know much about these. Next, I will introduce the methods of renovating old doors and windows and how to choose coatings.

1. Renovation method of old door and window paint

1. First, remove all metal parts such as hinges, locks, door suction and hooks from the old door.

2. Next, carefully check whether there are nails, gun nails, thumbtacks and transparent glue.

Others are sanded.

4. Then, fill the joint with putty powder.

5. Finally, draw pictures.

2. How to choose coatings?

1. When we buy, first of all, from the performance point of view, a good coating has high solid content and low volatile solvent VOC content. Paint with high solid content has a large brushing area. There are also coatings with low solid content, which may be cheaper, but if you want to brush to the same thickness and fullness, you must buy more; Or buy the same amount of paint, you can only brush it very thin, and the thickness and fullness of the paint film are not enough.

2. Next, in fact, a good coating has high hardness, good wear resistance and stronger adhesion to the substrate, which makes the service life of the coating longer.

3. More importantly, the selected coating is more transparent and can fully reflect the characteristics of the substrate.

Then, our good paint has better yellowing resistance and lasts as long as new.

5. When purchasing, good paint has better construction performance and smoother and more beautiful film.

6. Finally, the solvent of the selected paint volatilizes quickly, and you can't smell anything after painting for a few days. But I would like to remind you that some of our paints are open.
