Sanding sealer is practically a lacquer that is applied to wooden products or wood to get an even top coating. But to achieve all these benefits by using a sanding sealer, proper usage of it on wood or wooden products is a must.
Thereby, a common question can be raised in your mind that do you have to use a sanding sealer before stain or after. So, let’s quickly find the answers to this query.
Do You Use Sanding Sealer Before Stain Or After?
Sanding sealer is formulated as a base layer that’s supposed to be applied on bare and unstained wood or wooden floor, furniture, and other products before staining them so that it fixes pores and the wood or wooden products can be sanded afterward to get an even, polished finish.
The sanding sealer is basically an apparent liquid-based product that is designed to be used on natural and colorless wood or wooden flooring, furniture, and any type of wooden product before getting the desired stain on them.
It’s because the sanding sealer is developed with such a formula that would help the woodworkers to improve the quality of subsequent layers of stain or clear polish by sealing pores and fixing the rough texture of the wood or wooden products.
And with the fixed-up pores, the wood or wooden products achieve a very smooth, poreless, and even surface. Therefore, the stain/paint can spread out decently and cover the wood/wooden products’ surface instead of being quickly absorbed.
Besides, the sand sealer dries in just one hour while leaving a polished wooden surface behind prior to staining. However, it’s always best to sand down the wood/wooden products slightly with a 320 or 400 grit after the sand sealer has dried up and before staining.
Light sanding will remove the sand sealer from all the less permeable spots while leaving the sealer at more porous spots that help in achieving uniform staining without affecting its effectiveness.
Can You Use A Sanding Sealer Over Stain? Can You Stain Wood After It Has Been Sealed?
The sanding sealer manufacturer companies don’t really recommend using a sanding sealer over the stain.
It’s because a sealer is sanded down after sealing the rough, uneven, porous texture of the wood so that it creates a protective base coat for smooth staining in the next stage.
Thereby, if the wood has already been stained, using a sanding sealer isn’t effective, this can’t be used on it as sanding the sealer afterward will abrade away the stain.
You can stain a piece of wood after it has been sealed only if you sand off the sealer from the piece of wood to a stage where the surface is still smooth but the shine has stripped off fully. It will allow the stain to go through the pores of the wood and will spread out evenly.
Sand by using a coarse sanding block/sanding paper to remove the polished shiny finish from the wood.
Which Goes First Wood Stain Or Sanding Sealer? Can I Use Sanding Sealer As A Finish?
As the name implies, a sanding sealer should go first always before the wood stain because a sanding sealer functions as the base coat on natural wood surfaces that have been once sanded down already to a bare finish.
When a piece of wood is sanded down to an unfinished bare stage, it still has a rough texture with several pores. So if it’s stained before applying a sanding sealer, the wood will have an uneven rough finish, as a result, the sanding sealer needs to go first before the wood stain.
As the sanding sealer will fill out pores and rough texture it can be again sanded down to a stage where the excess sealer be scuffed away leaving a smooth yet porous enough surface to soak up the wood stain.
You can’t use a sanding sealer as the finish over the wood, as the sanding sealer isn’t really a finish that is meant for giving the wood surface a finish coat and even if you use it as a finish it will not hold up well.
Besides, a sanding sealer is supposed to fill up the pores and fix the wood, it will not add any protective layer as the finish coat does. Rather, it will require a sanding step again that will abrade the stain.
When Should I Use A Sanding Sealer?
You should use a sanding sealer after sanding down the wood to a natural and bare finish and prior to staining it with either a water-based or oil-based wood stain.
If you want to get a better appearance after staining the wood beyond its original finish and want to minimize discoloration, you must use a sanding sealer before you want to achieve your desired stain.
But don’t use a sanding sealer after staining as after using a sanding sealer, it needs to be sanded down to remove excess sanding sealer from flat spots. As a result, the stain can get scuffed away during this process.
