When you own your own house, you will definitely want your house to be different from others, so you need to put more effort into decoration. Wooden putty is like wooden furniture. Clothes can not only cleverly cover up defects such as insects, knots, and color differences on the wood surface, but also highlight the beautiful texture of the wood. Today we will take a look at the use methods and construction points of wood putty!

How to use wood putty

1. Material preparation

The materials needed for wood putty construction mainly include wood putty and wood putty. There are three commonly used wood putties: nitro putty, polyurethane putty and water-based wood putty.

Wood putty can fill in joints, scars, nail holes and other defects on the wood surface, saving materials and labor when applying wood putty. At the same time, it can improve the smoothness of the putty surface and increase the appearance of the wood. Beautiful surface.

Comparison of the main varieties of wood putty

Nitro putty (NC) has better decorative effect; fast drying speed; easier to repair; lower solid content; durability, gloss retention, and color retention The performance is not good; the environmental protection is poor.

The polyurethane putty (PE) putty film is plump and thick, with good gloss and transparency; it is hard and wear-resistant, and has strong adhesion and is difficult to repair if the putty film is damaged; it dries slowly; and the film easily turns yellow.

Water-based wood putty (W) has good environmental protection; it does not yellow, has excellent water resistance, and does not burn; the hardness of the rust-proof and high-temperature resistant water-based putty is not high; the construction environment requirements are relatively high.

2. Tool preparation

Some tools are required when constructing wood putty. Commonly used tools include sandpaper, filters, brushes, emery cloth, spray guns, roller brushes, etc.

Sandpaper is used to polish the wood board surface, the filter is used to filter impurities in the wood putty, and several tools such as brushes and spray guns can be used to choose different painting tools according to different painting methods. .

3. Working environment

Wood putty construction is a very precise and meticulous job and requires suitable environmental conditions. Temperature, humidity, light, ventilation, hygiene, etc. all meet certain requirements to achieve a good putty surface effect.

Temperature: It is best to carry out at normal temperature (15-30℃). If the temperature is too low, the putty film formation will slow down; if the temperature is too high (over 35℃), the painting performance will be adversely affected. .

Key points for the construction of wood putty

1. Construction specifications for clear oil painting

Sanding the base layer is an important process for applying clear putty. The surface of the wood should first be Remove dust, oil and other impurities.

Applying oil powder is also an important step in applying putty. During construction, dip cotton silk in oil powder and apply it on the surface of the wood. Rub it back and forth with your hands to rub the oil powder into the surface of the wood. In the eyes.

When applying clear oil, hold the oil brush in a relaxed and natural manner, and apply gentle pressure with your fingers, so that the brush does not loosen or fall off when moving.

When brushing, you should follow the requirements of dipping more frequently, less oil each time, working frequently, and brushing smoothly. Follow the requirements of first up and then down, first difficult and then easy, first left and then right, and first inside. Construction should be done in the order of back and outside and the operation method of horizontal brushing and vertical brushing.

2. Construction specifications for oil-contaminated wood surfaces:

When treating the base layer, in addition to cleaning up the debris on the base layer, local putty embedding should be carried out. When sandpapering, the surface should be sanded smoothly. Polished to match the wood grain. Before painting the surface layer, use putty sheets (shellac putty) to seal the knots with large color differences and lignin.

Dry oil or clean water should be applied to the base layer. When applying the dry oil layer, all parts should be brushed evenly without any omissions.

After the base oil is completely dry, apply the first coat of putty. After drying, sand it with manual sandpaper, and then top up with high-strength putty. The putty shall not fall over even if it is picked up. When applying the surface layer of putty, sand it with fine sandpaper first. If you apply putty on one base and two sides during decoration, you must sand it three times with sandpaper. The first sanding is after the putty is applied and before you start applying the first putty. Be sure to use sandpaper to sand the wall surface that has been putty applied and has dried. .

Making your own small furniture at home is fun and warm. Looking at the furniture you have made, you must feel a sense of accomplishment. Don’t forget to paint the wooden furniture after it is finished. The above is the small The method of using wood putty and construction points that I will introduce to you today ends here.
