Rubberseal Trowel Grade is a White, elastomeric, trowel- or brush-grade waterproofing caulk, filler and sealant. A waterborne, high-solids elastomeric formula with high-performance, weather-resistant pigments. It is
specifically designed for waterproofing, sealing and filling: holes, valleys, cracks, vents, low spots, flashings, seams and other probable or vulnerable leaking areas. Rubberseal Trowel Grade is a multi-purpose caulk and sealant which was designed for roofing surfaces, but can be used on walls, floors and virtually any substrate, horizontal or vertical. Dries to a tough yet flexible rubberlike sealant, with minimal shrinkage. Excellent waterproofing, bonding and sealing characteristics. Very easy to apply and can be painted over with most any compatible exterior paint or coating.
USES:
Rubberseal Trowel Grade can be used on horizontal and vertical surfaces or substrates including roofs, walls, floors, etc. Excellent adhesion on weathered wood, shakes, plywood, clapboard, primed metal, galvanized, aluminum, tin, copper, primed styrofoam, fiberglass, built-up-roofs, bonded roof gravel, rolled roofing, mineral surfaced roofing, concrete tiles, clay tiles, masonry tiles (flat or barrel), primed synthetic or aluminum, adobe, slate, slab, properly prepared EPDM, and various other substrates. Rubberseal Trowel Grade is ideal for residential, commercial and industrial applications.
APPLICATION PROCEDURE:
Do not thin, use product as is. Do not apply when temperatures are below 45 degrees Fahrenheit or when humidity is very high. Do not apply when caulk will be subjected to rain or heavy dew before it has had enough time to dry (approximately 4 to 6 hours). Drying time will vary depending on temperature, humidity and location. Apply using a stiff brush or trowel. Patch any holes, cracks, flashings, valleys, vents, etc. and any low spots or vulnerable leaking areas. Rubberseal Trowel Grade will seal seams, but for severe applications inquire about Rubberseal Geotextile Fabric. Spread uniformly. When filling deep holes, more than 1 square inch, apply multiple coats and build the patch up and allow for minimal shrinkage. Sets to touch in approximately 2 hours and dries in approximately 5 to 24 hours depending on thickness of application. The thicker the Rubberseal Trowel Grade is applied the longer it will take to dry. Rubberseal Trowel Grade can be coated over in 12 hours, but be careful not to disturb the patch since it will dry from top to bottom. Rubberseal Trowel Grade should be top coated with a compatible exterior paint or coating and should not be left uncoated.

Corners done
Four corners. One afternoon. No sagging.

Container was difficult to reseal
Product performed well, but cleaning the rim thoroughly enough to reseal the lid took time. A smaller project left me with extra, so storage mattered. Plan for that before the rim gets messy.

Stayed vertical
Main thing I needed. Main thing it did.

More craft than painting
Rolling is repetitive; troweling requires feel. By the fourth penetration I understood how much pressure to use. The learning curve is real but manageable.

Filled an awkward transition
Our addition has a strange step between two roof levels. I could shape the trowel grade into a gradual transition, something a roller alone could not accomplish.

Too much for my tiny repair
Product is fine. I bought way more than needed.

Harder than YouTube
People in videos make troweling look effortless. My first pass looked like cake frosting applied during an earthquake.

Great around a roof curb
The roll-on handled the open roof, while this filled and shaped the curb transitions. Using each product where it made sense produced a more coherent job.

Detailed a set of planter corners
Used the thick grade in every internal corner before coating the broader surfaces. It created a smooth radius and removed the sharp angles where I was most concerned.
DIY Homeowner –
Did what the thin material couldn’t
I had one isolated depression that needed actual build, not another cosmetic coat. This let me shape the area and correct the transition before finishing the project.
PlanterPerson –
Not for covering acres
Excellent at corners, seams, and isolated low spots. Miserable idea for a broad flat area unless you enjoy troweling all day. I paired it with the roll-on and would do so again.
Fatima R. –
Looks handmade because it is
My finish has some ridges, but the area is hidden and the build is solid. If this were visible, I’d spend more time learning to feather the edges.
The Caulk Whisperer –
Hot weather shortened my patience
The afternoon heat made me rush, and rushed trowel work looks rushed. The morning section was much smoother. Product seems good; schedule and temperament both matter.

Took practice
First corner: 25 minutes. Last corner: 8 minutes. Buy cheap practice board if finish matters.
Caleb D. –
Not pretty
My workmanship, not the product. Hidden corner so I’m living with it.

Trowel matters
Small flexible blade. Trust me.

Good combo
Trowel grade first, roll-on after. Makes sense.

Tiring by hand
Lots of little details. Forearm was cooked by lunch. Final result looks strong.

Got it everywhere
On the roof, my glove, the ladder, somehow my phone case. Mask and stage a cleanup area.
GutterGoblin –
A useful problem-solver
This is not the glamorous part of the project, but it handled the irregular gaps and transitions the roller couldn’t reach. The final coat tied everything together.

Saved a troublesome parapet detail
Built up the inside angle, embedded reinforcement, and finished over it. The material stayed exactly where I worked it. This was the missing piece in my repair system.
MudRoomMike –
Small trowel, big improvement
Swapped a six-inch trowel for a narrow putty knife around pipes. Night-and-day difference. The material is controllable when the tool matches the detail.

Lumpy until mixed
Needed a better stir than I gave it. Smooth after that.
