What are the acceptance standards for parking lot floor paint

The epoxy floor paint construction of the indoor parking lot has unwritten construction guidelines, which are evolved and optimized during the long-term use process. The experienced construction team will have a clear division of labor and cooperation, and dedicated personnel will be responsible for their respective construction projects. Both clear division of labor and collaboration, thereby improving construction efficiency and construction quality.

In the acceptance of parking lot floor paint, it is necessary to consider whether the construction quality meets the standards, but also whether the construction is reasonable. A parking lot floor with qualified construction but unreasonable planning will affect the daily management work, and may cause some dangerous accidents in serious cases. Therefore, the parking lot floor construction needs to master its professional essentials, and the acceptance must be carried out strictly !

1. The essentials of parking lot floor construction

1. The parking lot floor should adopt professional construction technology

The weight of the vehicle and the friction of the tire are a great burden for the floor paint. If you want to work under high load for a long time, you must adopt a professional parking lot floor construction plan, that is, "moisture-proof epoxy primer + mortar The professional construction of "primary coating + putty intermediate coating + self-leveling", depending on the traffic intensity of the occasion, appropriately increasing the thickness of the mortar intermediate coating can increase the load strength. The construction thickness of the paint layer should reach 1-3mm. For large shopping malls and high-rise commercial buildings, the recommended thickness should be above 5mm.

2. Reasonable arrangement of traffic lanes

According to the forecast of traffic flow, when planning the lane, the two-way lane width must be greater than 6m and the one-way lane not less than 3m; the sidewalk should be parallel to the traffic lane and the width should be between 1.5-2m; parking spaces, sidewalks, and lanes should be colored yellow Or separated by white line paint, the line width is 8-12cm. In addition, the three should use epoxy topcoats of different colors to improve their recognition.

3. Parking space specifications

Usually the parking spaces that can be passed by a small car are 2.5-3m, and the length of the car is between 5-6m. Therefore, according to the specific situation of the site, the parking space should be planned, and the size of the parking space should be adjusted according to the actual situation. Under the premise of "as consistent as possible" "Adjust measures to local conditions" and should not be too rigid and cause a waste of space. For example, there are more than three positions planned between the two columns, but four are not enough. If the construction is rigid in accordance with the three-position specifications, the excess space will be vacant and affect the perception; at this time, the width of the parking space should be appropriately increased, which is beautiful It also makes parking operations easier.

Set a backstop rod at 1-1.2m from the rear line of the parking space to prevent vehicle collisions.

4. Obviously reasonable reminder signs

Obvious and reasonable warning signs should be planned on the ground, including driving directions, navigation directions, turning reminders, U-turn reminders, exit directions, and eye-catching reminders of vehicle intersections, etc. The reminders should be painted with yellow or white line paint , Consider using luminous paint to enhance the eye-catching effect.

Unreasonable signs may mislead the direction of the vehicle, resulting in congestion or even collisions. It often happens that there is no U-turn sign in the decapitation space. After the vehicle has entered, the following vehicle will follow up, which is blocked together and cannot be driven out.

Traffic signs should be able to reasonably guide vehicles to enter and exit the parking lot efficiently, so as to improve the orderly management of the parking lot.

5. Planning of cylinder and wall

The 1-1.2m high part of the lower end of the column should be roller coated with eye-catching colors. The usual method is to paint with reflective yellow and gray paint or white paint to form diagonal zebra stripes. The part above the zebra crossing shall be filled with the same color as the wall according to the plan and mark the area.

The treatment on the wall is similar to that of the cylindrical surface. The wall skirt at the lower part of 0.2-0.7m is painted in a reminder color system different from that of the ground and wall to serve the purpose of reminding and distinguishing. The part above the wall skirt is constructed in the same color as the column surface in the area to enhance the integrity and the function of rapid positioning.

2. Acceptance standards of parking lot floor

1. Inspection of flatness

First, use the light reflection method to observe whether the light source reflected on the floor has a large spot distortion, and then use a 2m ruler to measure. The flatness of the parking lot floor with a thickness of 3mm should be less than 2mm/2m.

2. Surface color inspection

Observe the consistency of the surface color, subject to no obvious color difference. The surface color is uniform, no whitish floating flowers, good gloss, no unevenness, uniform light and shade, no light leakage and bottom penetration.

3. Surface quality inspection

After 3 days of curing in an environment above 25℃, the curing quality will reach more than 80%, no scraping pattern and joint pattern, surface bubbles less than 1 within 10square meter, and a small amount of surface defects caused by dust in the air is allowed.

4. Paint strength inspection

Use a 1KG steel ball to fall freely at a height of 1m to detect whether the paint is cracked or damaged, subject to no obvious change. For wear test, samples should be sent to a professional organization, and the 2H hardness shall be freely stroked back and forth 10,000 times without penetration.

5. Slip resistance inspection

A professional friction tester is used to determine the surface friction coefficient. Usually, manual comparison is sufficient. The friction coefficient of epoxy floor is more than 20% higher than that of cement floor, and higher friction resistance can be clearly felt. Therefore, a simple comparison can determine its anti-skid performance.

The above parking lot floor paint projects should be planned in advance during construction. Each point has an important impact on the parking lot after it is put into use, so comprehensive and reasonable planning must be carried out before construction.

Strict acceptance after the completion of the construction is the guarantee for the maximum value of the floor in the future use. Therefore, each acceptance standard should be strictly implemented. In order to achieve high-efficiency and high-quality floor quality, it is recommended to choose a professional team with construction qualifications for construction, so that the project can be guaranteed to the greatest extent!
