This is what you need to know about the best stain blocking ceiling paint

Ceilings often get water and mud stains due to leakage from the rooftop or any other reason.

To avoid these stains, stain-blocking paint should be used, which not only hides the stains from showing but also enhances the life of the ceiling paint.

Thus, a coat of primer can also be a plus in this process as the primer seals the stain from appearing on the outer ceiling and helps the paint stay longer.

Moreover, multiple stain blockers are available in the market, making it difficult to rank any product as the best stain-blocking ceiling paint.

However, there are multiple ways to block stains, and each painting may include a different formula to help secure the ceiling stains.

The article below will illustrate the various methods available in the market for blocking ceiling stains through paint or other options.

Water-based, oil-based, shellac-based, and paint coat, all these methods can help stop colors in their unique way. Keep reading to know more about your options to resolve the issue.

Paints that block stains on ceilings

The market is full of multiple products, all claiming to be the best stain blockers, while choosing one actual best is a difficult task.

The article below will illustrate the features of the best stain-blocking ceiling paint for your ease and let you make a wise choice by knowing all the features to look for while making a decision.

Thick paint, which includes water and oil shellac and dries faster, is mostly preferred for covering heavy and light stains.

In contrast, other options, such as water-based stain blockers, oil-based stain blockers, and shellac-based stain blockers, are also under discussion to make you aware of the different choices available in the market.

Features To Look In Best Stain Blocking Ceiling Paint

  • Thickness in the texture means the paint is suitable for covering old and heavy stains from the ceiling due to its thick coating.
  • It should contain acrylic, primer, water, oil, and shellac ingredients. All these ingredients together can make the best stain-blocking ceiling paint.
  • White paint holds the most power to cover all the stains with its colorless base and neutral texture.
  • Paint that dries faster is the best option, especially in steamy areas such as the walls and ceiling of bathrooms.
  • The best paint is the one that is good to use on both the interior and exterior rather than two different options, from which one is suitable for the interior and another is for the exterior.
  • Paint that only needs one coat to hide or block all the stains is the best choice.
  • Paints that can be applied directly to the damaged surface stains are the best, rather than those that need to work on stained surfaces before applying the coat of paint.
  • Paints with the feature of micro-pores

Different Types of Stain Blockers 

1. Water-Based Generic Stain

Water-based generic stains are effective only in removing minimal stains, such as stains caused by cigarette smoke.

This is the cheapest and most convenient formula available to remove minor stains.

However, the water-based formula is unsuitable for stubborn and heavy stains as it only removes light stains and those not so aged.

Persistent and old stains need more heavily formulated and thick textured paints to remove or hide the colors on the ceilings and walls.

2. Oil-Based Stain Block

Some stains are very stubborn and difficult to remove. Oil-based stain blockers work very effectively with such marks.

Stains like watermarks, stubborn graffiti, heavy grease, and nicotine need paint to remove such effects from the ceiling or walls.

An oil-based stain blocker works best here, as it contains the ingredients that are very helpful in removing these marks that are causing the beauty of your area to diminish with their stubborn appearance.

So, those are the major differences if you want to know about water-based stain vs. base stain

3. Block Finish Coat And Stain Block In One

With the advancement of technology, more and more new techniques have been introduced in the market, and one in this field is the introduction of paint and stain remover as one product.

Here, the final coat of paint works as the stain remover and blocks almost every type of stain except for the marks resulting from water.

Additionally, this type of paint provides a perfect finish to your work by removing every stain.

To see the final results, it is essential to leave the area painted for at least 4 hours after the last coat is done to see more good results after the wall, ceiling, or any other place where paint is applied, dried fully and completely.

4. Shellac-Based Stain Block

Shellac is an effective formula for removing stains that other options available in the market fail to remove.

Thus, to use shellac, some points should be considered before making use of shellac.

These are mainly to use low-price equipment for applying shellac or paint as tools may get wasted after using shellac due to the texture of shellac, which remains on the instrument forever.

So it’s preferable to use cheap and low-quality tools which should be used once and then wasted.

Moreover, shellac is less a paint and more a primer, which works best as the coating on the blocking stains is considered one of the best stain-blocking ceiling paints.

At the same time, fewer people will make you aware of its essential feature: to work as a primer rather than color.


In light of the above article, a conclusion can be drawn that the best stain-blocking ceiling paint should contain thick texture features and must-have ingredients such as shellac, acrylic, oil, and water for better and quicker results.

In addition, an effective stain blocker should possess the feature of micropores and work effectively on uneven, old, surfaced stains.

In contrast, white paint is always preferable when blocking and hiding stains, while paint that can work with just one coat is always a go-to product for users.
