HP Precat WW Clear Dull 5 Gallon is a medium solids, true water white vinyl sealer from ML Campbell that lays down a clear base coat, which supports natural wood color where a neutral undercoat is needed. The sealer exhibits excellent dry time, so coated work can move to the next step of the finishing schedule without long delays. Its nonyellowing performance keeps the sealed surface from shifting toward an amber tone, which matters when matching light finishes or painted systems. Strong adhesion properties help the sealer bond to the substrate and to subsequent coats, building a finish system that resists peeling in service. Designed as a seal coater whenever contamination is suspected, it creates a barrier layer that helps isolate problem substrates before topcoating. Good moisture and chemical resistance in the sealer adds protection in demanding interior environments where routine contact with liquids or cleaners is expected.
This ML Campbell vinyl sealer is intended as a seal coater whenever contamination is suspected, so it serves as a first layer between the substrate and later coats in challenging situations. It is also intended for projects where a sealer with good moisture and chemical resistance is desired, giving the finish system a more robust foundation. When top coating with a post catalyzed product, 1 ounce of C149 1 Care Catalyst per gallon of MC123319 can be added to further improve performance, tying the sealer into higher-performance topcoat systems. ML Campbell notes that FD Vinyl Sealer is specifically designed for use with the WW Hi-Performance Pre-Cat Lacquer (MC12224 series), showing how their sealers and lacquers are coordinated for system use. The same FD Vinyl Sealer can also be used as a sealer for any MLC pre-catalyzed lacquer, post catalyzed lacquer, conversion varnish, nitrocellulose lacquer, and CAB lacquers, which gives shops flexibility to build finish schedules around multiple ML Campbell technologies.
This water white vinyl sealer is intended as a seal coater whenever contamination is suspected, so it fits jobs where substrates may carry residues or previous coatings that need isolation before finishing. It is also intended for situations where a sealer with good moisture and chemical resistance is desired, positioning it for cabinetry, fixtures, or woodwork that experience frequent contact with moisture and household chemicals. As a medium solids vinyl sealer, it sits in the finish stack as the base layer, letting finishers build clear or pigmented topcoats over a consistent barrier. Because it is nonyellowing and true water white, it works particularly well under systems where maintaining a light or precise color is critical, such as light-toned woods or pigmented finishes tied to sample standards.
The excellent dry time of this ML Campbell HP Precat sealer shortens the wait between application, sanding, and topcoating, which helps maintain a steady line in small and large shops. Strong adhesion properties support reliable bonding to both the substrate and subsequent coatings, which reduces the likelihood of finish failure in service. Its sanding properties help the sealed surface level easily, so minor grain raise or irregularities can be smoothed before building film thickness. The nonyellowing, true water white character keeps color shifts to a minimum, which aids finishers working to tight color-matching requirements. When the system uses a post catalyzed product, the option to add 1 ounce of C149 1 Care Catalyst per gallon of MC123319 can further improve performance, aligning the sealer with higher-performance topcoat demands. The related FD Vinyl Sealer is specifically designed for WW Hi-Performance Pre-Cat Lacquer (MC12224 series) and can also be used with MLC pre-catalyzed lacquer, post catalyzed lacquer, conversion varnish, nitrocellulose lacquer, and CAB lacquers, giving shops a coordinated approach to multi-product finishing systems.
HP Precat WW Clear Dull 5 Gallon is a medium solids, true water white vinyl sealer from ML Campbell, so it functions as the sealing layer in a multi-step wood finishing schedule.
The excellent dry time of this vinyl sealer allows quicker movement to sanding and topcoating, which supports faster production cycles and reduces bottlenecks at the finishing stage.
The nonyellowing, true water white character keeps the sealed surface visually neutral, which helps maintain accurate color on light woods and pigmented finishes over time.
This ML Campbell vinyl sealer is intended as a seal coater whenever contamination is suspected or when good moisture and chemical resistance is desired in the finish build.
When top coating with a post catalyzed product, 1 ounce of C149 1 Care Catalyst per gallon of MC123319 can be added to this system to further improve performance.
FD Vinyl Sealer is specifically designed for use with WW Hi-Performance Pre-Cat Lacquer MC12224 series and can also act as a sealer for several other ML Campbell lacquer systems.
HP Precat WW Clear Dull 5 Gallon provides a medium solids, true water white, nonyellowing vinyl sealer base that supports color-critical and moisture- or chemical-exposed projects. For coordinated finishing schedules across ML Campbell technologies, this sealer and the related FD Vinyl Sealer align with pre-catalyzed, post catalyzed, conversion varnish, nitrocellulose, and CAB lacquer systems. Selecting this ML Campbell HP Precat sealer adds a dedicated sealing layer that addresses contamination concerns and builds toward durable, repeatable wood finishing results.
