|Frequently Asked Questions|
|Q||How to use powder spackling (The use of substandard glue in the basal layer is the main cause of excessive VOC and odor in the interior wall.)|
|A||Before applying latex paint, the wall surface is required to be not only flat but also smooth and delicate. Therefore, the interior wall needs to be smoothed. In daily construction, powder spackling, old powder, finished spackling are commonly used. The powder spackling can be applied with water, while the old powder needs to be glued. The glue contains a lot of formaldehyde and pungent taste, so after the completion of the overall wall construction, there is odor problem in the room. Many customers mistakenly believe that it is from latex paint. Therefore, Lianian recommends to use powder spackling and finished spackling for construction.|
|Q||Reasons for alkaline surfaces: ( The wall is not flat with shadow or uneven gloss)|
1. The coatings become alkaline due to the high alkalinity of the cement base layer or the poor quality of the spackling.
2. There is water seepage inside the wall, or the matrix is too loose and the humidity is high. After raining, the water vapor evaporates outward.
3. The primer is poorly sealed and is not resistant to water or alkali.
|Q||Blister problem( After the coating is dried, spherical blisters are locally formed with liquid or air inside, or even rupture.)|
Cause: The surface treatment is not complete
(1) Residual oil, water, dust, etc.
(2) Painting on the wet surface, too much water inside the paint tool or adding too much water will increase the viscosity of the paint which leads to thicker coating.
How to prevent: completely clean the surface, keep it dry, dust-free, oil-free, and water-free. Make sure the tool is squeezed out to a suitable state or repeatedly applied to the wall after being rolled through the tray. Freshly painted wall should be protected from high temperatures and direct sunlight.
How to deal with: polish the base to the depression of the blisters and recoat.
|Q||Crack and peel problem(After the coating dries, it loses its adhesion,causing the crack and the wall starts to peel off.)|
Reason: The adhesion of the spackling is not enough; there's still dust left on the layer. The surface to be coated is too smooth, there's still water, oil, wax, oxide scale, etc. The coating is too thick, and the middle layer is oily, waxy, or repaired with spackling.
How to prevent: completely clean the surface before painting, make sure the spackling must be firm, and there won't be any powder when handcuffed. The coating should not be too thick.
How to deal with: Remove the loose and peeling parts, sand the edges with sandpaper, and increase the firmness of the spackling layer anda the paint primer and finish.
|Q||There's trace of painting( After rolling, there are traces left)|
1. Improperly hair length of the roller
2. usage of low quality paint
3.usage of low quality roller
4.incorrect operation skills
regarding the roller hair, choose proper length. It can't be too long. And use high quality roller to make sure the thickness and uniformity of the coating. Also use high quality paint to ensure the leveling and stable performance. If there's water in the roller, try to clean that. Do not let paint to accumulate at the end of the roller. Brush the paint down from the edge of the ceiling. When brushing, start with “M” or “W” shape. At the beginning, roll up in the upward direction to reduce splashing. Do not leave the wall after painting, and make “M” or “W” shape to obtain uniformity and flat paint film.
|Q||Why should we apply primer?|
|A||The role of the primer is to seal the base and enhance adhesion. For example, the alkali-resistant primer can be alkali resistant. The use of primer usually improves the overall effect of the topcoat and also reduces the amount of paint used for the topcoat.|
|Q||About leakage during delivery？|
All of our products support unpacking and check before sign it. If the product is leaky or deformed, please take photos and reject it in time. Contact the customer service online to re-issue it. We will contact the courier company directly to deal with the broken one.
|Q||The tinted products cannot be returned, and products can not be returned after the security code being scraped!|
|A||Due to differences of colors, the painting is divided into two types: light color topcoat and dark color topcoat. Paints of different colors neeed different colorant. Once you have decided the color, you can find the customer service for corresponding paint.But the colored paint belongs to customerize product, so it can't be return. So the area to be painted must be well meassured. Only the products that are not colored, unopened, and the anti-counterfeiting code is not scratched can be returned. Single barrel can be returned by single, but set must be returned by set with intact packing, no damage, leakage and dust.|
|Q||How much water can be added to the latex paint?|
|A||Under normal circumstances, no need to add water to dilute, if you need to add water on special circumstances, we recommend: add no more than 10% water per barrel (mineral water is preferred) and less than 5% if it's tinted product, dark color product is not recommended to add water (dark-based color), the coverage power will decrease after adding water.|
|Q||How long can we live after painting?|
|A||Different products have different eco-friendly levels and VOC content. Zero VOC latex paint can be lived the moment you brush. Our ultra-low VOC products only need to be ventilated for 3-5 days.|
