Deckmaster™ Sealer


DeckMaster® Concrete Sealer

State-Of-The-Art, Waterborne PolyUrethane/PolyAcrylic Coating

Clear & Pigmented Sealer for Concrete, Masonry & Aggregate Surfaces

Product Description

The DeckMaster® Concrete Sealer is a one-of-kind, waterborne, self-crosslinking PolyAcrylic-Urethane surface sealer and coating designed for exterior and interior use. This fast drying, fast curing system shows "lacquer-like cure rates" making it ideal for decorative and traditional uses on a wide variety of horizontal and vertical masonry and wood surfaces. It can be used as a true clear, transparent, semi-transparent or full body finish. This totally new technology self-crosslinking polyacrylic resin not only has superior ultraviolet light resistance but also exhibits very fast drying properties not known to exist with any other single component water-borne product. Deckmaster® generally shows complete water repellency in 1 ½ hours at 77 degrees F and 50% humidity making it ideal for coastal exposures and multi-color projects requiring many coats/operations. DeckMaster® can be sanded in 1 hr @ 77° F making it ideal for Decorative Faux and multi-color finishes on kitchen cabinets, floors, and driveways as well as wall applications including bathrooms. Apply up to 3 coats/day for fastest possible job completion times. DeckMaster® is specifically designed for ease of maintenance with recoats being very easy. Has superior resistance to traffic and most common household chemicals. Properly sealed surfaces have excellent food stain resistance. Meets USDA requirements for food service.

In independent testing conducted by a decorative concrete floor tile manufacturer, DeckMaster® has shown superior adhesion, curing properties, water repellency and scuff resistance to all other waterborne sealers tested. For light foot traffic situations, DeckMaster® can be used as its own topcoat. For maximum traffic and chemical resistance, we recommend topcoating with RUSTOP 6000 Metallic, Traffic Max or Graffiti Max (solvent-borne urethane).

Surface Preparation

Remove dust, grease and oily deposits with FSC Driveway Cleaner or strippers. New concrete surfaces should be aged 60 days minimum. Exterior concrete surfaces (particularly new), which are steel trowel finished, must be mechanically abraded (ex. bead blast or sandblast) or acid etched with FSC Etch & Clean (phosphoric acid cleaner/degreaser) diluted 4 to1 with water (acid must be neutralized with baking soda) to insure proper penetration & adhesion.

IMPORTANT: Always thoroughly saturate surrounding masonry, granite or stone surfaces with water prior to acid etching and rinsing steps. If acid beads on entire surface or any spot on surface, special degreasers or strippers must be used first to remove imbedded oil or sealers/finishes prior to proceeding. Use of rotary scrubbing machines with coarse abrasive pads (usually black) is helpful for stripping, degreasing and acid etching operations. Sprinkle baking soda on wet floor at ½-1 lb/100 ft 2 & work-in with garage broom. To remove excess salts and debris, surface must be thoroughly rinsed after each step of etching & neutralizing (power wash is best; garage broom with water 2nd best).

Plan rinse water flow pattern to ensure that driveway, walks, walls, etc are not damaged by rinsing operation. Use pH pencil to ensure pH between 6 to 9 after neutralizing. Do NOT use Muriatic Acid or Hydrochloric Acid as floor will fail.

Optional Rinse or Power Wash Procedure for those concerned about damaging adjacent masonry or stone surfaces: Acid wash surface, neutralize floor & remaining acid on floor with baking soda and then power wash or rinse floor once to minimize acid attack on adjacent surfaces. Be sure to rinse all adjacent surfaces to prevent salt build-up on adjacent surfaces. Using this option will require more baking soda to neutralize surface & lingering acid solution (1½ - 2 lb/100 ft2) with possibly more residue left behind. Must wet all adjacent surfaces PRIOR to rinsing acid etched surface to minimize discoloration or damage of adjacent surfaces.

Surface to dry overnight or longer at 77 degrees; 50% R.H. If high moisture remains, white spots, weakened film strength, coating damage and/or disbonding may result. Turn off all water sources. Use of fans for increased air movement is very helpful; add heat if temperature is below 65˚ F or if humidity is above 65%. If white spots occur in heavy DeckMaster build-up, sand build-up down to substrate, allow moisture to escape for 48 hrs @ 77˚ F and reapply DeckMaster. To be effective and prevent peel, DeckMaster Systems must be allowed to penetrate into the masonry, concrete or asphalt matrix.

When applying DeckMaster to terracotta pavers (Mexican Pavers), slate or flagstone, bricks or fired tile (ex.: Italian tile), use Tile & Brick Preparer™ followed by power wash to achieve proper adhesion. Follow instructions from FSC as to use of Tile & Brick Preparer.

Hard water deposits from landscaping water or regular hosings can leave a white film or spots on DeckMaster surface - use Z-90 Wood Magic™ (try first) or Etch & Clean™ (stronger, try second) plus abrasion/agitation with maroon ScotchBrite™ pads to remove light build-ups. For heavy hard water deposit build-ups, sanding for deposit removal and DeckMaster reapplication may be necessary.

For cracks, seal with Geocel 2300 Tri-Polymer Caulking or 2315 RLF Brushable Caulk. For deep or wide cracks, use of backer rod is recommended prior to application of 2300/2315. Saw cutting or routing of some cracks required. Do not use water-based caulks or standard urethane caulks. 2-3 caulk beads may be required to fill deep and/or wide cracks - allow for shrinkage of each coat and proper 24 hour cure time between Geocel applications.


Important Note for High Moisture Slabs and Walkways: For floors, walkways, garages or driveways withefflorescence or high water content (above 15% moisture content) at any time of the year, apply deep penetrating Silox-Seal to minimize or even stop water migration through the masonry.

DeckMaster is at minimum a 2-coat system; some surfaces require more coats, especially when using PolyGrit. Use golf shoes during application so can walk on recently applied coating without damaging it. Best to spray or roll apply in thin, surface wetting coats. Even if spray used, "work" into the surface with a roller immediately after application. Keep roller wet - do not dry roll as stipple or uneven texture may result. The first coat is intended to penetrate deeply and sheen may appear very uneven in many cases - if surface is very porous, coating may almost disappear. If coating essentially disappears into substrate within 5 to 10 min, apply more DeckMaster immediately as part of 1st coat. Allow 1 st coat to dry 1-2 hours in most cases before recoating.

"Work" the second coat with a roller into the second coat to ensure the best possible inter-coat adhesion. Do Not Leave Puddles On Horizontal Surfaces!!! A uniform sheen (satin or gloss) should result after the second coat if the surface is properly sealed. A third coat may be required (if PolyGrit is used) or desired if the surface is very porous (such as flat block, split face block or sandblasted surfaces). The porosity and temperature of the surface/substrate influence the amount of sheen and resulting surface wear characteristics. Porosity determines the amount of product required for each coat.

On warm days or hot surfaces, do not apply in direct sun as "flash" dry may occur with unsightly roller stipple patterns resulting, coating "bubbles" appearing and possible loss of adhesion and film abrasion resistance. If the film bubbles or strength loss occurs or adhesion loss occurs, stripping of weakened film is required with complete reapplication necessary.

Equipment Application: DeckMaster Sealers may be applied by spray, roller or brush.

1. Roller: Use ¼"-⅜" lint free roller. Work out of a paint tray or pour directly onto work area. Only work each area with a couple strokes-cure is very quick! If excessive roller stipple occurs or excessive roller "pull" occurs, the area is being over worked. Work roller in front of the body, not side to side.

2. Spray Applications: Use standard airless or HVLP equipment with a 50% overlapping stroke. Uniformity of sheen will depend on the uniformity of porosity and application technique. Recommended spray tip size & pressure: 0.015 - 0.019" tip orifice @ 900 - 1200 psi. Backroll recommended for best adhesion properties.


1) ALWAYS APPLY DeckMaster TO TEST AREA BEFORE PROCEEDING WITH FULL APPLICATION PROCEDURE. Multiple coats are required - if DeckMaster is applied in a heavy single coat, peeling, disbonding, softened film properties and premature wear patterns may result. Do not apply to previously sealed surfaces unless test area is undertaken with adhesion testing performed to ensure proper inter-coat bonding. Neither AMTECO nor FSC warranty any application over another coating system.

DeckMaster Clears have an inherent slight yellow color that varies from batch to batch. Do not use DeckMaster as a clear coat or topcoat over a pigmented surface without first testing the coating material from the batch to be used to ensure acceptability.

2) DeckMaster Sealers and Coatings do NOT form a true waterproofing system. Water migration through stone, brick or masonry surfaces can result in disbonding of DeckMaster Coatings and surface efflorescence. For balcony or elevated decking surfaces, true high build waterproofing systems such as All-Deck are recommended.

Spread Rate
New Smooth Concrete Floors 200-300 ft² / gal
Old or More Porous Surfaces 150-200 ft² / gal

Stucco, Very Porous Decking & Vertical Surfaces 100-150 ft² / gal

Concrete Pavers & Unsealed Block 80-100 ft² / gal

Split Face Block; PolyGrit Anti-Slip Applications 60-100 ft² / gal

"Water Resistance Testing" is recommended. After 24 hours of cure, flood DeckMaster coated surface with water to ensure water seal. When using clear DeckMaster, mark dark areas (where water has penetrated). After 24-48 hour dry, apply DeckMaster to marked areas and repeat test to ensure water seal.


1. Though not a problem to date, it is possible that "hot" tire marks could be left in material in applications where vehicular traffic is present.

2. Tinted materials will require more frequent maintenance coats than clears.

3. Allow test samples to age for 1 month for full evaluation before undertaking full project.

4. Where maximum traction is desired, incorporate "POLY-GRIT"™ non-slip additive @ 5-7 oz. by volume of "POLY-GRIT"™ per gal of DeckMaster. Mix in "POLY-GRIT"™ & stir with drill mixer. Apply mix with roller. When applying DeckMaster mixed with "POLYGRIT"™, apply 3 coats of DeckMaster to hold the "POLY-GRIT"™ and achieve evenness of texture. Yearly and bi-yearly maintenance is required on such applications.

5. Deckmaster will not stop water migration or efflorescence from underneath the surface.

6. Negative side water and edge water migration (as from landscaping sprinklers) can cause white spots and/or lifting & peeling of DeckMaster.

7. Consider SILOX SEAL™ for horizontal areas where efflorescence is a problem prior to applying DeckMaster. For sidewall sealing applications, consider Prime&Seal™ and Silox-Seal™ because of their superior vapor transmission rates and "breathability".

Thinning & Cleanup: Thinning not required except during high temperatures or when used on "tight" surfaces. Add up to 16 oz. water per gal DeckMaster when surface temperature exceeds 90°F or when penetration into a "tight" surface is a concern. Use soap & water cleanup.
