Varnishes, choosing the right one
Its composition and finish determine the product that should be used on each surface.
Varnishes provide protection. In particular, parts or areas exposed to wear gain resistance thanks to their action.
They improve the result with professional finishes, while also achieving greater durability.
Depending on the surface or material they will be applied to, there are different types of varnishes. Choosing the most suitable one guarantees a perfect finish.
The painting and carpentry work is enhanced by the varnishes.
They camouflage scratches and cracks, protect against fire, or counteract the effects of humidity and water vapor in rooms such as the bathroom or kitchen.
They are mostly applied to the floor and furniture, outdoors.
BASIC CONCEPTS TO CONSIDER BEFORE CHOOSING A VARNISH
WATERPROOF VARNISH
A water-repellent varnish is a varnish that repels water, but is not waterproof . When applied, water rolls off, but over time it loses this property and is not suitable for permanently pooling water.
It can be applied when we don't need to waterproof, but we want to secure the support.
Water-repellent varnishes are usually breathable, allowing the substrate to breathe.
WATERPROOF BANIZ
A waterproof varnish can never be breathable, as it creates a plasticized layer. A good waterproof varnish must resist water pooling (puddles on the floor, cleaning with hoses, etc.).
COLORLESS OR TRANSPARENT VARNISH
Colorless or transparent varnish is one that, when applied, allows the support to show through, but we must also take into account that it will visually change its appearance, in that it will raise the tone of the support.
For example, on stone, brick, etc., it will give a wet effect. If we want to know roughly how it will look after applying it, we just need to wet the wall a little to see the final tone after applying the varnish.
INVISIBLE VARNISH.
Invisible varnish is that which, after application, shows no visual difference from the unvarnished piece.
We can use it when we want to varnish interior stone walls, and we don't want it to raise the tone of the surface.
SOLVENT-BASED VARNISH OR WATER-BASED VARNISH.
The main difference between the two is the smell. Water-based varnishes don't smell when applied, and we don't need to ventilate afterward, unlike solvent-based varnishes (which can have a slight odor for 1 or 2 days).
The areas where they are applied can be used immediately with water-based varnishes.
The difference lies in whether we need a higher quality varnish, whether for waterproofing, for better adhesion to the substrate, for greater hardness and resistance to traffic or external agents, etc.
Solvent-based varnishes are usually of higher quality and more resistant than water-based varnishes.
WHAT QUESTIONS DO I NEED TO ANSWER BEFORE CHOOSING A VARNISH?
- Do I need a waterproof varnish, or do I want to protect and secure the support?
-Do I mind if the varnish enhances the tone of the material being varnished? I want it to enhance the tone of the support!
-I want a breathable varnish, one that allows the surface to breathe?
-Where am I going to apply the varnish? On a floor, a wall, wood? Will it be walked on by people or cars?
-Do I need a water-based varnish or can it be solvent-based?

WE MUST MAKE THREE MAIN GROUPS WITHIN WOOD VARNISHES
OPEN-PORE VARNISHES OR WOOD STAINS
Open-pore varnish for wood is a varnish that does not create a layer, so over time it will disappear, but it will not cause peeling or flaking, and it does not need to be sanded to apply another coat of varnish or stain, either at the time or when we need to varnish the wood again.
When applying this type of wood stain or varnish, we must keep in mind that we will not visually see when the wood needs to be varnished again (because it will not create flakes), but that does not mean that the wood is protected; we must check our windows or doors, etc., annually so that they remain protected.
CLOSED-PORE OR SYNTHETIC VARNISH.-
Synthetic wood varnish is the most widely used for protecting and decorating wood; it can be used in gloss, matte, or satin finishes.
It is a closed-pore varnish, which does not allow the wood to breathe.
It provides films with great hardness and resistance to rubbing and abrasion. It leaves no brush marks.
Very suitable for the protection and decoration of wood, indoors and outdoors.
Completely washable, even with household detergents.
TWO-COMPONENT VARNISH OR POLYURETHANE.-
Two-component polyurethane varnish is the highest quality and offers great physical and mechanical resistance.
We will use this varnish for wooden floors that will have foot traffic, or mechanical or chemical friction.
We will use it when we want to give a higher quality protection to our outdoor wood, against atmospheric aggressions.
This exterior wood varnish has a FIREPROOF or FIRE RESISTANT certification, and we can use it when we have wooden walls, ceilings or floors and want to give them greater protection against fire, as it prevents the spread of fire.

We have three main groups of floor varnishes: for wooden floors, for stone, concrete, etc. floors, and for painted floors.
WOOD FLOOR VARNISH
When the floor we want to varnish is made of wood, we can see the difference between varnishes for wood floors in the previous point, WOOD VARNISH.
Varnish for stone, tile or concrete floors
When the floor we want to varnish is made of stone, stamped concrete, masonry, brick, tiles, etc., we can find out the most appropriate varnish for each surface and situation ; we will use almost the same varnishes as for exterior walls or facades.
It is a varnish that, due to its properties, is used for sealing stamped concrete floors.
It is used for sealing and protecting concrete, both decorative and stamped concrete pavements.
High durability, far exceeding most products on the market.
Very suitable for resin coating of stamped concrete pavements .
Excellent water resistance, water repellency.
VARNISH FOR PAINTED FLOORS
Normally, with a good floor paint, we won't need to varnish the floor after painting it.
But even if this isn't the case, you can use some type of varnish, always taking into account the type of paint that is currently applied to the floor.
You can never use a varnish stronger than the paint applied, because it would remove it.
If this is your case, we advise you to consult us personally, and our technicians will be able to advise you individually, depending on the support situation and its use.
Call us or get in touch. We'd be happy to advise you.
