Do you have to sand tile before painting?

Should I sand walls before painting?

The answer to this question depends. Sanding is not necessary for every painting project. But if your walls have rough spots – whether or not they’ve been painted before – you will need to sand them down. Use sandpaper to smooth out any uneven surface. Then, wipe away dust and debris with a damp cloth and allow it to dry.

You should also sand walls before painting if your surface was previously covered with a gloss or high-gloss paint. Use a fine-grit sandpaper for water-based paint, and a medium-grit sandpaper (around 100- to 150-grit) for oil-based paint. Again, you’ll want to remove dust and allow the surface to dry thoroughly.

Cracking, blistering, and flaking paint can also be an issue. Painting over damaged paintwork is never a good idea – it’s essential to remove flakes with a scraper or sandpaper before you begin.


Do you have to Prime After texture?

Following the Manufacturer Instructions

With some manufacturers, priming over the texture is not required before you paint. Keep in mind that while it’s not necessary, the textured surface you are painting is already uneven, so priming would only help to ensure an even appearance to the coat of paint.

How do you paint orange peel texture?

How To Paint Orange-peel Textured Wall Treatments
  1. Wipe down orange-peel walls with a damp sponge to ensure no dust or grime is on the walls. Paint will not stick to dust.
  2. Use a medium-nap roller to roll two coats of drywall primer over the orange-peel wall treatment. Allow each layer to dry from 2 to 4 hours.
  3. Add your latex finish paint to the wall’s surface.

What to wash walls with before you paint

Answered By: Morgan Harris Date: created: Nov 30 2020

Dust and clean the walls. For most surfaces, use a towel or a vacuum cleaner. When painting a bathroom or kitchen, wash the walls with a solution of approximately three teaspoons of laundry detergent to one gallon of water. Scrape any cracked or flaking paint with a paint scraper.

Do you need to sand bare before painting?

It may seem unnecessary to sand bare wood before painting, but stock lumber is often coated in a glaze to help protect it. Removing that coating will help the paint adhere. In addition, sanding opens the grain of the wood, which can also help with adhesion.

How to Sand Spindles

Often times, I get asked how to sand chairs with spindles or how to sand spindle table legs.  Unfortunately, you can’t use an electric sander on spindles but I do have a trick to make it go faster.

Fold over a sheet or piece of sandpaper until you have a long piece about the shape and length of a ruler.

Then, wrap it around the spindle and move it back and forth.  Revolve the sandpaper around it once or twice.  Remember you are not trying to take off paint, just rough up the surface.

Step #1: Cleaning Walls Before Painting

As seen in our How to Prep Walls for Painting video, clean walls are key in preparing a room for painting. While there is no best way to clean walls before painting, most walls can be washed using a sponge and warm water. For surfaces that have exposure to oil or grime, like kitchen walls, wash with a solution of water and grease-cutting detergent and follow up with clean water to remove any residual cleaning agent. Finish by wiping the walls with a damp cloth. The most important part of the process is to make sure you let everything dry thoroughly. Applying primer or paint to walls that are still damp can cause a host of issues, including blistering. Interested in learning how to clean walls you’ve already painted? Read this.

Do I need to scrape off old paint exterior

Answered By: Diego Morgan Date: created: Oct 31 2021

No, you only need to scrape off old paint not properly adhering. Not all old paint. If any paint is flaking, curling up, this must all be removed, easiest way is scraping. Using a hand or powered tool, remove all this paint off of surface, before going any further.

What is the best type of sander for sanding walls?

Sandpaper, sanding block, or orbital wood sanders

Sandpaper is ideal for small projects, and you can have a sanding block to hold it down. Meanwhile, a random orbital sander is for ease when smoothing the wall. Sanding plaster walls with it can give the surface a cleaner and flatter finish.

Step #3: Sand Surfaces Before Painting

While sanding is not required for every paint project, rough spots on walls, whether they have been previously painted or not, need to be sanded before they are painted to ensure the paint goes on smoothly. Use sandpaper or a sanding block to dull any uneven surfaces, wipe away dust with a damp cloth and let dry thoroughly. Smoothing walls before painting is necessary for surfaces previously painted with a gloss or high-gloss paint. For previously painted water-based paint, sand with a fine-grit sandpaper. For oil-based paint, a medium-grit sandpaper (100- to 150-grit) should be used. Again, wipe away any debris and allow to dry completely. Cracking or flaking paint on previously painted surfaces can also be an issue. Paint cracking on walls and ceilings happens due to a variety of causes, one of the most common being poor preparation of a surface prior to painting. Painting over cracked paint is a bad idea; it is important to remove any flakes from the surface via sanding or scraping before repainting.


If your walls have dents, cracks, or holes, then it is important to seal up any open crevices before beginning the painting process. Paint is incapable of filling in these spaces due to its thin texture, so painting over them will just leave them exposed. You can easily and quickly fill in holes and cracks with spackle. Spackle is a type of paste that you can smooth over holes and cracks, filling them in and ensuring that they are sealed. 

True Value states, “Spackling paste or spackling compound is made of gypsum powder and binders and is used to patch small holes, cracks and other imperfections like dents in drywall, plaster walls, and sometimes in wood.” This way, when you begin painting, the final look will result in a smooth, clean wall.

Most spackles these days can dry within 10 minutes, so they won’t set you back on schedule if there is a last-minute hole that you need to fill in. Some are designed to change color from pink to white, so you know when it is dry and safe to sand down. It is important to sand the wall after spackling in order to ensure a flat and smooth surface for your paint. 

What happens if you don’t sand before painting?

The reason we’re so often told to sand wooden furniture before painting is because sanding helps to open up the wood, making it more susceptible to sticking to the fresh paint.

Sanding also removes any bumps and impurities from the wood which would make it look uneven and messy.

If you don’t sand before painting you will likely end up with an uneven finish and a paint job that will likely end up peeling after a few months.

You may also be able to see any lighter or darker patches of the book come through the paint which looks ugly and unprofessional.

Questions  Answers

Questions Answers

Question: How do I paint a red wall white?

Answer: You'll need to prime the wall white with a good latex primer. I use Sherwin Williams products the most. Their Premium Wall and Wood Primer or Multi-Purpose Primer both work well for this purpose. But any quality latex primer will do the job.

Question: Do you sand the wall between coats of paint?

Answer: I always sand walls before painting, but usually not between coats, unless the walls aren't smooth from the initial sanding. I keep a sanding sponge in my pocket so I can spot sand rough spots if I need to.

Question: Do painters typically paint over drywall anchors?

Answer: I always remove them if possible, or knock them into the wall and patch the hole. If the anchor is metal and close to the surface of the drywall though, it should be primed first to prevent corrosion.
