Best Sealant Between Concrete And Wood

Keep Your Concrete Expansion Joint Watertight And Crack Resistant With Sikaflex Sealant

How To Seal A Gap Between Concrete Slabs

Gather all your old socks and a few worn-out T-shirts.

Youll need them as rags .

Sikaflex self-leveling sealant comes in two size tubes. The large tube is 29 fluid ounces and the small tube is 10 fluid ounces.

If you have a huge concrete expansion joint to fill I highly recommend the 29 fl oz tube. Youll have to buy a large caulking gun but this will save you a ton of time.

Heres a Third BIG TIP:

Think about how many tubes you need then BUY twice as many.

Again, talking from experience here. Its so much easier to buy a ton of sealant then return what you dont use.

With the backer rod in place, you can cut the Sikaflex tube so that it will make a 1/4 inch bead. You might be tempted to cut the tube bigger but dont.

Once the sealant starts flowing it can be hard to stop and a bigger bead means youll have to work faster. Not to mention, but I will anyway, the huge potential mess you might have. Visualize sealant on your pants, hands, shoes, hair..

Pierce the seal inside the tube with an old wire hanger, the kind you get from the dry cleaners.

Place the tube in your caulking gun and pretend youre Dirty Harry. Just kidding. This step is unnecessary and only meant to make you feel cool .

Squeeze the Sikaflex sealant into the concrete expansion joint and allow it to flow & self-level itself. Add more Sikaflex where its needed.


Your concrete expansion joint is now watertight and way more unlikely to crack.

  • Thanks Martin, I have been watching closely and made them redo a lot of things. Do you think I should add polyurethane caulk to the sill plate – slab boundary at this time?

  • |#8

    With the exterior walls up and sheathed I wish you the best of luck OP !

    Just remember when you talk to your contractor that your concern is that even though PT lumber won’t rot it will still take on moisture and you’re concerned about the end grain of the studs sitting on the pressure-treated sill plate taking on this moisture.

  • Caulk is going to trap water inside in this case, either redo it or don’t caulk. I hope the builder got good insurance.

  • Expert Member|#10

    Caulking the seam will help air seal it, and won’t appreciably affect the drying capacity of the sill plate.

    The pressure treated sill plate should be able to tolerate some moisture wicking, and unless you are in the lowest swamp on the gulf coast it won’t become saturated. The sill plate and the studs mounted to it will be able dry into the open cell foam toward the interior as long as there isn’t any interior side vapor barriers . It’s less than ideal, but it’s not an automatic disaster.

  • I think the caulking will at least keep ants from coming in. I am retro sealing my house now, due to ants.

    You want to make your house as airtight as possible.

    If your house gets flooded, and you have standing water in your house, I advise you to open the door.

  • How To Bond Metal To Concrete

    Adiseal will successfully bond all metals to concrete in interior & exterior applications. As described above, it is vital to have clean surfaces where the adhesive will be applied to.

    Some metals may have an oil applied to it to stop the metal from rusting. This oil needs to be removed before the adhesive can be applied to between metal to concrete. Adisolve is ideal at removing oil, grease, tar & many other stubborn deposits.

    To achieve a strong bond, lightly scratch the surface of the metal where the adhesive will be applied to. This will increase the surface area allowing for a stronger bond. Some methods include using sand paper or a file to scratch the surface. Clean the surface thoroughly after scratching the surface to remove any loose metal.

    Once the surfaces are clean, simply apply the adhesive between metal to concrete and firmly push together. Temporary supports may be required if the items slide down. Adiseal Hi-Grab adhesive has even higher initial grab and may eliminate the need for temporary supports.

    For safety reasons on extra heavy metal items, mechanical fixings also need to be used between metal to concrete in conjunction with Adiseal when used to bond heavy items to vertical & overhead applications.

    How Long Will Polyurethane Sealant Last

    When properly applied, polyurethane sealant can last for 5 to 10 years. The specific lifespan of a sealant may vary depending on the type of surface it is applied to, the amount of traffic it receives, and the climate conditions it is exposed to.

    Generally, sealants exposed to harsh weather conditions or heavy traffic will need to be replaced more frequently than those not. Regularly inspect surfaces sealed with polyurethane and repair or replace any damaged or failing sealant.

    Now you know everything from applying sealant between concrete and wood to its lifespan, which concludes our article. We hope you can not choose the best sealant between concrete and wood and make a robust waterproof barrier.

    When Should Concrete Be Resealed

    Most concrete should be resealed every 1 to 3 years. However, this will depend on the type of sealer used, the amount of abuse it is exposed to and so forth.

    Signs that you may need to reseal:

    • Water no longer beads on the surface, but instead soaks into the concrete
    • The sealer appears scratched, worn, dull or dirty

    How long concrete sealers last:

    • Penetrating sealers containing silicate, silane, or siloxane last longest, sometimes a lifetime
    • Soft acrylic coatings wear the fastest, needing reapplication every 1 to 3 years
    • Epoxies, polyurethanes and polyaspartics are much harder than acrylics lasting 5-10 years

    Concrete Sealers For Indoor And Outdoor Surfaces

    Can You Use Sealant Between Foundation And Sill Plate

    Applying sealant between the foundation and the sill plate can protect it from the elements. The sill plate is the horizontal board that sits on top of the foundation.

    Using the sealer will help keep them separate. In this way, you can prevent water damage to your foundation and discourage pests from entering your home.

    To apply sealant properly, you will need to use a caulk gun or airless sprayer and apply a generous amount of sealant around the perimeter of the sill plate. After applying sealant, you can use a putty knife to smooth it out and create a seamless bond between the foundation and sill plate.

    Problems With Using Glue On Concrete


    Glues are generally suitable at sticking small items to smooth surfaces but not for more heavy duty applications like gluing items to concrete. For more heavy duty applications, a construction adhesive like Adiseal will be required. Glues have lower gap fill, initial grab, bond strength, flexibility & other problems compared to Adiseal adhesive & sealant when trying to stick items to concrete. As concrete is porous it will require sealing first so that it does not soak up any liquid glue. This is not a problem for Adiseal adhesive & sealant.

    Application Process For Concrete And Natural Wood Sealers

    The application process for concrete sealers and sealants for natural wood is very similar. Both products should be applied in a thin coat and allowed to dry completely before applying a second coat. Be sure to follow the manufacturers instructions carefully when applying either product.

    It is important to note that concrete sealers are not designed to protect wood from moisture damage. If you are looking for a product that will protect your wood from water damage, be sure to select a sealant specifically designed for wood.

    A Brief Introduction To Mastic Sealants

    Behr Premium Semi

    A sealant is a form of material, which is used to seal gaps and holes to make something airtight or watertight.

    When you use sealant, you effectively form a seal, which prevents the movement of fluids and liquids.

    Sealant is sometimes compared to caulking.

    The main difference between building caulking and sealing is the flexibility of the seal. If you include mastic sealing in this equation sealants can not only seal but can also be used as an effective adhesive.

    Sealants tend to be made from much more flexible materials.

    This makes them useful for areas and joints where a degree of contraction or expansion may occur.
