The full version
Detailed application instructions.
Non-Skid first, then the sealer it goes into, and the complete garage, pool deck and deck systems.
01 Strip, sand and dry
Prep E · 60-grit · no cleaner
- Pressure wash to remove dirt, algae and loose fibres.
- Sand off every trace of old stain, sealer or paint with 60-grit. The coating bonds to bare timber, not to what was on it.
- Vacuum or blow off all dust.
- Let the wood dry fully — days, not hours, after washing. Wood holds water long after the surface looks dry.
02 Reinforce joints and end grain
You’ll need: Fabric Reinforcement · Liquid Membrane
End grain is the thirstiest part of any board and the first place rot starts. Treat it before you coat the field.
- Coat the joint, board end or transition generously.
- Lay Fabric Reinforcement into the wet coating and press it flat.
- Wait 10–15 minutes, then coat over it to encapsulate.
03 Three coats of membrane
Each coat: 15–20 mil. Keep every coat in that range — thicker traps moisture and stays tacky, thinner leaves the membrane short of waterproof.
- Stir the product well — pigments settle and unstirred product gives uneven color.
- First coat goes into the timber and will look thin. That’s the wood drinking it, and it’s normal.
- Recoat when it holds no fingerprint. Run each coat perpendicular to the last.
- Three coats on bare wood. Inspect for thin spots — it dries lighter, which makes them easy to see.
04 Cure, then seal
Wait about 2 days after the last coat of membrane, then seal: three coats of Titan Shield Gloss or two of Sealer MATTE, about 6–8 mil per coat, with Non-Skid Additive mixed in. The membrane still needs its full 7-day cure before heavy use.
| Each coat | 15–20 mil · thin and even |
| Bare wood coverage | ~100 sq ft per gallon at 3 coats |
| Previously coated | ~150 sq ft per gallon at 3 coats |
| Sealer coverage | Titan ~150 · Matte ~120 sq ft/gal |
| Sealer over membrane | ~2 days after the last membrane coat |
| Sealer thickness | ~6–8 mil per coat |
| Initial cure | 7 days minimum · longer if humid |
| Temperature | 50–90°F · out of direct sun |
| Prep | Prep E — sand with 60-grit, no cleaner |
01 Degrease, then Prep D
You’ll need: a degreaser · Nu-Lift Cleaner · Stone Soap
- Degrease oil and transmission stains first. No coating bonds to oil, and Prep D isn’t a degreaser.
- Wet the slab, apply Nu-Lift Cleaner and work it in with a stiff brush to lift efflorescence and mineral deposits.
- Rinse thoroughly.
- Follow with Stone Soap to clear the residue and rebalance the surface pH, then rinse again.
- Let the slab dry completely. Concrete holds water long after the surface looks dry.
02 Reinforce cracks and joints
You’ll need: Fabric Reinforcement · Liquid Membrane
- Fill anything wider than ¼" with a suitable filler first.
- Coat the crack or joint generously, lay Fabric Reinforcement into the wet film, press it flat.
- Wait 10–15 minutes, then coat over it to encapsulate.
03 Two coats of membrane
Each coat: 15–20 mil. Keep every coat in that range — thicker traps moisture and stays tacky, thinner leaves the membrane short of waterproof.
- Stir well — pigments settle and unstirred product gives uneven color.
- ½" nap roller on an extension pole; cut in the edges with a brush.
- Recoat when it holds no fingerprint. Second coat perpendicular to the first, same day.
- Inspect for pinholes and thin spots before you stop.
04 Cure, then seal
Wait about 2 days after the last coat of membrane, then seal: three coats of Titan Shield Gloss or two of Sealer MATTE, about 6–8 mil per coat, with Non-Skid Additive mixed in. The membrane still needs its full 7-day cure before heavy use.
| Each coat | 15–20 mil · thin and even |
| Membrane coverage | ~200 sq ft per gallon at 2 coats |
| Titan Shield Gloss | ~150 sq ft per gallon at 3 coats |
| SEMCO Sealer MATTE | ~120 sq ft per gallon at 2 coats |
| Sealer over membrane | ~2 days after the last membrane coat |
| Sealer thickness | ~6–8 mil per coat |
| Initial cure | 7 days minimum · longer if humid |
| Temperature | 50–90°F · out of direct sun |
| Prep | Prep D — degrease oil stains first |
01 Clean the surface
You’ll need: Nu-Lift Cleaner · Stone Soap · Power Cleaner if oily
- New concrete, fully cured (about a month): Prep A — Stone Soap.
- Mineral deposits or efflorescence: Prep D — Nu-Lift, then Stone Soap.
- Oil or grease: Prep B first — Power Cleaner, then Stone Soap.
- Existing or unknown coating: Prep C — Power Cleaner, Nu-Lift, Power Cleaner, then a test patch.
- Let it dry completely — below 3% residual moisture.
02 Mask off
Mask everything that isn’t being sealed. Pull the tape before the sealer fully cures, or it tears the edge.
03 Three coats
You’ll need: woven roller or airless sprayer (17 tip)
- Stir well before use to mix the pigment.
- Roll on a thin, even first coat. It goes on milky and dries clear.
- Let each coat dry — about 30–45 minutes, up to 2 hours when humid.
- Apply a minimum of three coats, about 6–8 mil each. Porous surfaces may need more.
04 Let it cure
Full cure is typically around 48 hours at 72°F — longer when cool or humid. Keep traffic off until then.
| Coverage | ~150 sq ft per gallon at 3 coats |
| Coats | 3 minimum · ~6–8 mil each |
| Dry between coats | 30–45 min · up to 2 hours if humid |
| Full cure | ~48 hours at 72°F |

Questions
The questions worth asking.
What is the Titan Shield Non-Skid Additive?
It is an anti-slip additive that mixes into SEMCO sealer to add traction on smooth surfaces like floors, ramps, and pool decks.
How do I use the Non-Skid Additive?
Stir it into the sealer before application; one version is sized for a 1-gallon batch and another for a 5-gallon batch of sealer.
Where should I use a non-skid finish?
Use it anywhere slip resistance matters, such as pool decks, walkways, ramps, and garage or patio floors.
Can I add it after the sealer is down?
No. It goes into the bucket before you roll. It can't be sprinkled over or added afterwards.
Which sealers does it work with?
Titan Shield Gloss and SEMCO Sealer MATTE. It isn't for Liquid Membrane on its own.
Does it change the color?
No. The grit is clear, so the sealer color stays the same.
Should I spray or roll?
With clear sealer, spraying gives the most even spread of grit. For rolling, a colored sealer is recommended.
How many do I need?
One per sealer container, the same size: For 1 Gallon or For 5 Gallon.
