How To Remove Excessive Paint From Your Canvas If You Have Made A Mistake

July 9, 2018

Not all paintings that we do are satisfactory. We make mistakes! Sometimes it might be a part of the painting which might look muddy or an area where there is excessive texture and we did not plan in that way. It could make you want to leave the whole thing or start over fresh because we feel it won’t work out otherwise. Just relax and read this article as we give you some tips to help you cover up the mistakes that you commit on canvas while painting.

The first and foremost thing is to not panic when you spot a mistake on the canvas, no matter how big it is. We all get attached to the work we do and sometimes it could also be emotionally exhausting so to objectively clear the mess it is important that you also think clearly. It does not matter if the paint is acrylic, oil or pastel – you can always find a way to fix it. The most effective way is to white out the area where you have spotted a mistake and begin it fresh. However, in doing so very often the painting loses the texture and quality. This could be a major issue mostly if your entire painting is thin and the area which you have repainted starts looking more vibrant compared to the rest of the painting, which will be noticeable to viewers.

Titanium White

The best way to cover up a mistake on a painting is to apply two coats of titanium white over it. This colour is opaque and can cover almost all colours including darker shades such as black. However, it is advisable to apply two coats only and not more. This will provide you with a fresh base to start over when it has dried away. Don’t confuse titanium white with zinc white, as the latter is more transparent than the former. Also, make sure that you paint it completely white and leave no stains of the colours beneath it to ensure a clean base.

Wet Paint

This technique is more applicable for oil paintings than acrylics since acrylic paints dry up quickly as compared to oil paints. Oil paints do not dry up fast and take sufficient time.

  • Try to sweep off as much paint as you can with a painting knife without hampering the fabric.
  • Take a soft cloth and gently wipe off as much paint as you can. However, make sure that the cloth used is not dragged across other areas of the painting. It could cost you big!
  • You can add some solvent to the cloth and then wipe off if there is excess paint or stain still left on it.
  • In doing this ensure that you have not damped the cloth a bit too much. It only needs to be slightly dry with a bit of water. You would not want water dripping on your canvas and ruining the rest of the area.
  • Make sure once this is cleaned you allow the area to dry completely. This could take 2-3 days in the case of oil paints.
  • Once the area has died down completely, apply two fresh coats of titanium white and let it dry completely.
  • You can now repaint the area.


Tonking is a beginner’s technique that is mostly used to erase a mistake while doing oil painting( For oil painting, you can refer to ). If you want to redo an area where you have committed a mistake or add texture to a certain place talking bits of help. Here’s what you need to do:

  • Take a piece of paper of the same size as the area you want to cover and remove the paint from.
  • Now gently put it over the painted area (which should be wet also) and put pressure with your hand without damaging the canvas.
  • Now take the paper away from it gently.
  • You can repeat the process as long as there is no more paint left in the area.
  • If you still notice stains of the paint on it, take a small cloth and put some oil painting solvent on it and wipe it on the area, without touching the other parts of the painting.

For Dry Paint

You can apply the following technique in case of acrylic paints:

  • Sand down the area where you want to repaint with a sandpaper.
  • If you come across wet paint in the process, just remove it with a palette knife.
  • Take a damp cloth in order to remove away stains or excess paint.
  • Now let the area dry for a day and then apply two

In the kitchen, we will always face the problem that solid food needs to be separated from the liquid. (imagine noodle and soup).

Usually, using general funnel will make food remain in the mesh and also it is not convenient to pour out the liquid carefully.

At Chao Chen Design, I aimed at developing a product to make filtering more comfortable with only one hand.


Silica gel is safe, green and easy to clean.

Physically, it is flexible and can stand the temperature from -60 to 300 ℃.


1  Bend the food filter to fit in the food container.

(Owing to the elasticity of silica gel, this filter is applicable to different kinds of containers and can be firmly embedded on the edge.)


2 Pour out the liquid, then the solid food will be stopped by the meshes.

3 Food filter can be produced with various specifications of the hole size to
fulfill the requirement further.

4 After bending, this part is used to guide the flow.

5 The flexible silica gel can grab the container wall tightly to keep the filter in
position while pouring.

 When I traveled to North China (Ningxia, Inner Mongolian, and Dongbei), I was totally amazed by the northern landscapes and the freezing weather. Animated by the defoliation and frigid environment, I wanted to design a lamp to record the experience and bring the warmth to people in the north. So I utilized pipal leaves and developed a leaf lamp which transformed the fallen leaves into a warm lamp.

Countless leaves were colored into gold by the afterglow. In such a freezing day, I can still feel the warmth from that. I chose fallen leaves as raw materials and light as the media to show the beauty of nature in northern China.

RAW MATERIAL | Pipal Leaves

Pipal leaves have the plump tissue, regular shape, and clear veins.

The scenery in the north is completely different with those in the south. First time there,

I was immersed in the boundless sky, flying leaves and the magnificent sunset.


6 The light transmittance test of the lampshade.

5 The leaves were pasted based on the mold, a balloon;

4 The basic triangle was integrated with each other to form the area of lampshade;

3 Three leaves were connected together with white latex to make the basic triangle;

2 A thin layer of white latex was applied evenly on the veins and dried in the shade to enhance their toughness and strength;

1 The pipal leaves were boiled in 10% sodium hydroxide solution for 15 minutes and washed with water to remove the mesophylls tissue, leaving the veins;


The laminated leaves generate a gradual change from bright to dark. The warm lighting gently emitted from the lamp is as beautiful as the afterglow.

If you have any doubt regarding the process feel free to contact me.

5 Things to Consider when Buying a Shower Head

November 2, 2017

Buying a Showerhead can become a little confusing as you start browsing at the various different available designs and types of showerheads.

This is why we have created this article to help you out in the process of choosing the perfect showerhead for yourself.

Here are a few top things that you should consider when buying a showerhead for your bathroom:

1. Adequate Water Pressure

The first and foremost thing to test is the water pressure in the showerheads. Make sure that you don’t buy a showerhead which offers low pressure because otherwise, it would take you longer to bathe and rinse yourself.

If you go for a higher water pressure, then you would need to select a showerhead which comes with a higher gallon per minute or has a removable flow restrictor.

2. Showerhead surface area

Another important thing to consider is the size of the showerhead. If you buy a large showerhead then it could affect the water pressure of your shower.

Shower Head Surface Area

This is why it is advisable that you select a showerhead which is 8-inches or smaller in size as it would ensure that you have an adequate amount of water pressure to use. Also, large showerheads result in increased water wastage which is not an ideal scenario when using a shower.

3. Flexibility and Comfort

Another important thing to consider is your comfort. If you are a short person then a top mount showerhead might be difficult to manage as you cannot adjust it easily but if you are a tall person then you might not be comfortable with the low top mount showerhead too.

Handheld showerheads are usually ideal for most users as they are flexible and the long rubber hose allows you to cover a large area to clean. If you love relaxing while taking a bath, then a bath sprayer or a massage showerhead will be more suitable as it would provide your body with the adequate water pressure and pattern.

4. Budget

An important factor to consider when buying a showerhead is your budget. You will find different types of showerheads available in different price ranges so you can decide your budget and then search for a good showerhead in your budget.

If you want the lowest budget showerhead, then a fixed showerhead is the best product for you but if you want a little more luxury and comfort, then a handheld, rain or spray showerheads would be more suitable.

5. Easy to clean

Another thing to consider when selecting a showerhead is the ease of cleaning. Your showerheads and shower walls get dirty quite easily due to the soap scrub and mildew and if you don’t have a lot of time on hand to clean it daily, then you would end up with a smelly and dirty bathroom.

In such cases, a handheld showerhead is quite useful as you can rinse your showerhead and walls easily with it. That will be both quick and effortless. Still, have doubts, just ping me and ask all your queries.
