Wooden exterior stairs and masonry landscaping features must withstand constant exposure to the elements. To get that kind of durability, you’ll need precise installation and strong bonds between materials to prevent shifting or separation over time. In this guide, Fine Homebuilding pro, Sean Collinsgru, demonstrates how to use Loctite PL Premium MAX to ensure a secure, long-lasting connection between materials.
Proper preparation lays the groundwork for a successful stair installation. Start by evaluating the site, ensuring the layout supports adequate load distribution. Carefully position your stair stringers, checking for level and consistent spacing. Attention to detail at this stage will prevent future issues with uneven steps or structural weaknesses.
Gather necessary materials, including:
- Pressure-treated lumber
- Decking boards
- Exterior finish nails
- Wood screws
- Adhesive like Loctite PL Premium Max
Loctite PL Premium MAX will create durable bonds between all your wood components and hardware, preventing separation and ensuring long-term performance. Before applying adhesive, confirm that all surfaces are clean and dry.
Measuring the risers accurately is crucial for a uniform appearance and safe stair use. Double-check your measurements and mark cuts precisely to avoid costly mistakes. With everything in place, you’re ready to start building an exterior staircase that will withstand the elements and heavy foot traffic.
A secure exterior stair system starts with precision and strong adhesion. Using the right adhesive provides a durable bond between wood components and reduces the need for excessive mechanical fasteners. Follow these steps for a professional-grade installation:
Step 1: Position and secure stair stringers
- Confirm that the stair stringers are level and evenly spaced.
- Secure the stringers to the deck or landing using structural screws for stability.
- Measure and mark riser locations to ensure consistent step height.
Step 2: Cut and attach risers
- Cut riser boards to match the measured dimensions.
- Apply a heavy bead of Loctite PL Premium MAX along the stringers where the riser will attach.
- Firmly press the riser into place, ensuring it sits flush with the stringers.
- Check for consistent overhangs on all applicable sides. Sean Collinsgru recommends standard 1-inch overhangs for applications like residential stairs.
- Use exterior finish nails to hold the riser while the adhesive cures.
Step 3: Prepare and install treads
- Cut tread boards to length, ensuring a 2-inch overhang for safety and aesthetics.
- Drill a ½-inch hole in the Loctite PL Premium MAX tube to control adhesive flow.
- Apply a wide bead of adhesive along the top edge of each stringer. Your goal in applying the adhesive is both to join the materials and prevent moisture intrusion and rot where the wood screws penetrate the boards.
- Set the tread in place and press down firmly for a secure bond.
Pro Tip: Avoid overusing fasteners—adhesive alone provides a stronger, more uniform connection while preventing wood movement due to temperature and moisture changes.
With the stair treads secured, the structure is now built to withstand heavy use and outdoor conditions.
You can enhance the aesthetics of exterior stairs with adjoining masonry landscape features. To get the job done right, proper site preparation and strong material adhesion are essential. Loctite PL Premium MAX also provides a reliable bond between masonry materials like paving stones and garden blocks. Follow these steps to construct a stable and long-lasting masonry feature:
Step 1: Site preparation
- Begin by digging out several inches below the planned installation area.
- Add a layer of compacted gravel to provide drainage and structural support.
- Tamp the gravel down to the substrate level.
Proper base preparation is critical—without a stable foundation, masonry features may shift or settle unevenly.
Step 2: Laying the first row of pavers
- Position the starter row of paving stones, ensuring they are level.
- If the ground is uneven, use additional gravel to bridge obstacles and create a stable base.
- Check alignment frequently, as any inconsistencies in the first row will affect the entire structure.
Step 3: Bonding with adhesive
- Apply Loctite PL Premium MAX in heavy beads spaced 4 inches apart along each stone. You can cut the applicator tube to your desired bead width.
- Press each block firmly into place, using its weight to set the adhesive.
- Ensure consistent spacing between rows to maintain structural integrity.
Unlike traditional mortar, Loctite PL Premium MAX allows for expansion and contraction, preventing cracks due to temperature fluctuations.
Step 4: Stacking additional rows
- Repeat the adhesive application process for each new layer of masonry.
- Align stones carefully to maintain an even and professional appearance.
- Continue stacking until the structure reaches your desired height and allow proper curing between layers.
Outdoor construction requires adhesives that can withstand extreme conditions. Loctite PL Premium MAX is designed for high-performance bonding in exterior applications, with strong weather resistance and long-term structural integrity.
Superior strength and durability
PL Premium MAX forms a permanent bond between:
- Wood
- Masonry
- Concrete
Unlike mechanical fasteners alone, adhesives distribute stress evenly and reduce material damage and separation over time.
Weather and moisture resistance
PL Premium MAX resists rain, snow, and temperature fluctuations, preventing movement and deterioration in outdoor environments. Unlike traditional construction adhesives, PL Premium MAX remains flexible and allows for the natural expansion and contraction of joined materials.
Versatile applications
From decking and stair treads to retaining walls and garden features, PL Premium MAX bonds a wide range of materials, eliminating the need for additional fasteners. Then its gap-filling properties ensure secure adhesion even on uneven surfaces.
For contractors looking for professional-grade results in all outdoor conditions, PL Premium MAX is Loctite’s most durable adhesive with 100% solid curing.
To maximize the durability of exterior stairs and masonry features, follow these best practices when using Loctite PL Premium MAX:
- Surface preparation: Ensure materials are clean, dry, and dust-free before applying adhesive.
- Consistent application: Use a continuous bead for even bonding and structural integrity.
- Clamping and weighting: Secure materials in place to allow proper curing.
- Cure time: Although the adhesive starts to set within an hour, allow at least 24 hours for full strength before applying load.
- Regular inspection: Check for movement or wear and reapply adhesive as needed.
Applying these techniques ensures long-term stability and professional results in outdoor construction.
