Randomly check the formaldehyde pollution of 50 households with newly decorated rooms

The contract with the home improvement company in the decoration contract is only the first step. The long road to decoration has only just begun. In the middle of the renovation period, there are also many places worthy of your attention. Experts will remind you of such important links as payment time, decoration additions, and construction techniques.

[Teach you a trick]

Medium-term payment time is pre-agreed

Early in the interim period, we must pay attention to its motives. Just a few days after the start of the work, the workers always said that they had to enter the material. There was no money, and the medium-term project had already arrived, urging the owners to pay the interim payments. Normally decorated workers will not do so, but the hapless "home improvement guerrillas" often use this trick.

Experts: When signing a contract, it is best to limit the foreman through money. This has been repeatedly proven to be the most effective. Moreover, what links and standards should be provided for what money should be provided so as to avoid mutual ambiguity. The proportion of payment is best based on the proportion of 3,331, so that even if there are problems, it can be stopped in time.

Buying gadgets also requires receipt

"Home guerrillas" will always find you at the scene and send you to buy it, which is a little cheaper. In fact, many parts are counted in the project section. The decoration foreman suffers from no opportunity to slaughter the owner. Once there is an opportunity, especially when the owner purchases the contracted materials, he will always give you a list. The wire is not enough. It takes 2 wooden lines, etc. Because the sub-secondary, so the owners also feel that the money is not too much, returning accounts is not enough meaning, especially male owners, generally do not account.

Expert: "Home guerrillas" will not be stupid enough to allow owners to take advantage of him, but they will definitely take advantage of the opportunity to take advantage of the loopholes, so despite the loss of such small parts, the money is not much, but the purchase is to buy , The account is still to be considered clear, encounter the foreman who loves to dip cheap, it is best to leave an invoice or receipt after each purchase, to avoid being difficult to open, hard to argue.

"Hidden project" pays attention

The so-called "hidden project" is a construction project that has been concealed after renovation and cannot be seen on the surface. According to the renovation process, these "hidden projects" will be covered by the next process, so it is difficult to check whether the materials meet the specifications and whether the construction is standardized.

In recent years, due to the poor consideration of structural safety and fire prevention in the design and construction of home decoration projects, the following quality problems are likely to occur: As a result of the collapse of the ceiling in whole or in part, the ceiling becomes a “top drop”; Insufficient fixing of the package resulted in slumping; the leakage of the pipe caused damage to the ceiling; the buried route was buried under dangerous conditions; the substrate was not cleaned before painting, causing the paint to peel off and fall off.

Tiles should be soaked for half a day before use

The average home improvement will involve the decoration of the tiles. So what should we pay attention to when laying tiles?

Laying of wall tiles: Clean all types of dirt on the wall, and moisten one day in advance; Tiles must be soaked in clean water for at least two hours before the tiles are affixed. It is prohibited to stick with non-whole bricks when it comes to pipes, lighting switches, and bathroom equipment support.

The laying of ground tiles points: the tiles should be immersed in water for half a day before use, and bricks should not bubble; the kitchen and toilet should have a water gradient, no water, water does not flow back. Damage to the original waterproof layer during construction shall be treated with waterproofing. 12 hours of stagnant water test without leakage.

The quality inspection and acceptance points of the laying of the floor tiles must be firm, free of skew, warping, and empty drums; the overall surface is flat and the flatness error meets the allowable deviation requirements; the joints should be filled densely, straightly, evenly and width-wise, with no obvious dislocation.

8 points for carpentry

Similarly, in the home improvement process, woodwork will inevitably be involved. What should be noticed when accepting carpentry?

1. Look at the gap: It is the wooden seal line, corner line, waistline veneer to meet the seam not exceeding 0.2mm, the line and the line mouth slot joint does not exceed 0.3mm, the veneer and the plate meet does not exceed 0.2mm, the sliding door The error of the entire surface does not exceed 0.3mm.

2. Look at the structure: whether the structure is straight. Regardless of horizontal or vertical orientation, the correct carpentry practices should be straightforward.

3. Look at the corner: Is the corner accurate? The normal corners are all 90 degrees, except for special design factors.

4. Look at the parquet: whether the spell is tight and accurate. The correct wooden pattern is to be seamless or to maintain a uniform distance.

5. See arc: whether arc and roundness are smooth and sleek. In addition to a single, a number of the same shape to ensure consistency in the shape.

6. Look at the door: Is the cabinet door switch normal? When the door is open, it should be light and no noise.

7. Look at the leveling: The surface of the woodworking project should be flat, without drumming or breaking.

8. Look at symmetry: Symmetric woodwork items are symmetrical.

4 methods to control the quality of paint

Of course, the choice of paint is also very important. At present, there are many kinds of paints on the market. When choosing, you should pay attention to the following aspects:

To buy the heaviest package: lift up the paint bucket and shake it. If there is a crackling sound, it means that the packaging is seriously inadequate, there are two shortages, and the degree of adhesion is too low. The formal factory is real and can hardly hear the sound.

Estimate the amount of use: Buy one time to buy, so as not to have a slight color difference.

Choose the same brand: primer and topcoat are best to use the same brand or matching paint to prevent chemical reaction between primer and topcoat.

Standardize the construction sequence: remove dust and dirt on the surface of wooden products and lines (wood base layer); repair burrs on the surface of wooden base layer, lift defects, etc., use sand leather to polish, make corners neat; use oily putty (or transparent putty) for batch After scraping, polishing, and replenishing the putty, use the varnish to make up the brown eyes and nail holes and do the partial color correction work. Apply the paint over the first pass, reapply the putty, and remove the surface dust after polishing. After the paint is applied twice, the dust on the surface is removed after polishing, and the water is used to grind with the sand skin to repair the part of the hanging oil. The paint is applied the third time until the desired effect is achieved.
