Good to know
- Mix ratio depends on which Coval product you are adding it to. Call 817-676-6793 for the correct ratio rather than guessing on a live floor.
- Judge sheen from a cured sample under the building's own lighting. Wet coating tells you nothing about final sheen.
- Matting agent settles. Keep it thoroughly mixed and keep the batch consistent, or you will see sheen banding between passes.
- Sheen differences between batches show up worst on large open floors with long sight lines and overhead light.
About the Coval® Matting Agent
Coval Matting Agent is the sheen control component for the Coval sealer and top coat line. It is sold in 1 gallon and 5 gallon units and is added to the coating rather than applied on its own. Its job is straightforward: take a finish that would otherwise cure out glossy and bring it down toward satin or matte.
Sheen is a real decision, not a taste question. Gloss makes color look deeper and makes a polished or stained floor look wet and expensive, and it is easier to sell in a showroom or a retail space. Gloss also shows every scratch, every scuff line and every bit of dust, and it can be genuinely slick-looking under bright lighting, which makes some owners nervous. A lower sheen hides traffic marks, hides dust between cleanings and photographs better under skylights and storefront glass. On big open commercial floors and on residential interiors where the owner does not want a mirror, matte or satin is very often the right call.
Because the matting agent goes into the coating, the ratio you use is what determines the final sheen, and that ratio belongs to the specific Coval product you are mixing it into. We are not going to publish a number here that might not match your product and batch. Call Twin Coating Supplies at 817-676-6793 with the Coval product you are using and we will get you the correct ratio and mixing instructions from the manufacturer before you open a pail on a live job.
Mix a sample and cure it before you commit the floor. Sheen judged from a wet pail is not sheen judged from a cured surface, and lighting in the actual space changes the read again. One 2 foot by 2 foot cured sample under the building's own lights settles the argument faster than any conversation about matte versus satin.
What it is used for
- Taking Coval Ultimate Top Coat from gloss down to a satin or matte finish
- Commercial floors where gloss would show every scuff and traffic mark
- Residential interiors where the owner does not want a high-shine floor
- Matching the sheen of a new coating to an existing adjacent floor
Before you order
Work out how much you need
The most common ordering mistake in this category is buying by the gallon instead of by the floor. Coverage changes with porosity, profile and whether the coat is a base, a broadcast or a topcoat. Put the slab dimensions in and get a range rather than a single number.
How much material do I need?
Enter the slab. We will give you a range, because porosity and surface profile change real coverage.
- Floor area
- 400 sq ft
- Base coat
- 3.1 to 3.4 gal
- Topcoat (1 pass)
- 3.1 to 3.4 gal
- Flake
- about 8 x 25 lb boxes
Base coat, flake broadcast to rejection, then a clear topcoat. Order roughly 10% over on a first job.
Questions about this product
What does Coval Matting Agent actually do?
Coval Matting Agent is an additive that reduces the gloss level of Coval sealer and top coat finishes, taking them from a high-shine cure down toward satin or matte. It is mixed into the coating before application rather than sprayed or rolled on by itself.
How much matting agent do I add?
The ratio for Coval Matting Agent depends on which Coval coating you are mixing it into and on the sheen you are targeting, so use the manufacturer's instructions for that specific product. Call Twin Coating Supplies at 817-676-6793 with your product on hand and we will confirm it.
Should I choose gloss or matte for a concrete floor?
Gloss deepens color and reads as premium, which suits showrooms and retail, but it shows scratches, scuffs and dust. A matte or satin finish from Coval Matting Agent hides traffic marks and dust far better, which is why it wins on large commercial floors and most residential interiors.
Can I apply matting agent over a floor that is already glossy?
No. Coval Matting Agent is a component that goes into the coating before it is applied, not a treatment you brush onto a cured gloss surface. Bringing down the sheen on an already finished floor means applying another coat of matted material or mechanically abrading it.
Will matting agent change the durability of the coating?
Coval Matting Agent is designed as a sheen control component for the Coval system, so it is used within the manufacturer's stated ratio. Stay inside that ratio. Overloading any coating with matting agent to force a flatter look is what gets contractors into trouble with finish quality.
