Acrylic and urethane significantly differ in their durability and reaction to environmental stressors. Acrylic is generally less durable and more susceptible to scratches, UV radiation, and moisture. While it's often used for interior projects, it's less favored for high-traffic or outdoor applications.
PU kitchen cabinets are considered better for high-traffic kitchens due to their superior resistance to scratches and water. They are designed to handle more wear and tear, making them a durable choice for busy environments compared to acrylic cabinets.
Acrylic sealers are made from acrylic resins (both synthetic and water based) and used for caulking and sealing a variety of cracks and gaps. They are suitable for just about any DIY home project. Acrylic caulk protects your home by preventing the intrusion of dust, water, and insects into your home.
It's easy to do.
Polycrylic is not as durable as polyurethane and is meant to be used only on interior surfaces such as cabinets, furniture, and trim. It shouldn't be used in exterior applications or on surfaces that are subject to lots of wear, such as floors, or that are exposed to water.
Acrylic is not as durable as urethane. It can wear down faster than a urethane coating can, meaning it must be buffed or re-coated more often. The total additional maintenance costs can be pricier than just having urethane applied to your flooring.
Epoxy offers higher levels of rigidity and adhesion than polyurethane, making it better suited for harder surfaces.
Acrylic latex sealant is by far the most commonly used sealant for interior applications such as door and window trim, crown mouldings, chair rail, and other wood and composite trim. It fills the gaps, seals out weather, and cleans up very easily with water.
Acrylic sealers used as a pool deck sealer will also offer complete protection against damage caused by water absorption and surface abrasion. Acrylic sealers are slippery when wet however so it is important to add the Armor Non-Slip Additive to the acrylic if you are sealing your pool deck.
Acrylic sealers, on the other hand, are substances that will not penetrate the surface. They will instead form a protective film on the surface of the concrete, helping to protect the concrete by making it water resistant.
Disadvantages of Acrylic Sealant
Prone to Cracking and Shrinking: It is prone to cracking and shrinking over time. Cracking is worse when exposed to sunlight and severe weather conditions. Not Ideal for Wet Areas: Acrylic sealant is not water-resistant, which means it should not be used in wet areas.
No more than two thin coats of sealer should be applied to any surface indoors or out. Thick coats will result in an inconsistent finish with tacky areas that may not set- up correctly. Sealers applied with an applicator should be “pushed on” only.
FACTORS IN ACRYLIC SEALER DEGRADATION
True-acrylic sealers are non-yellowing when exposed to UV light. Temperature fluctuations: Changes in temperature, particularly frequent or drastic ones, can lead the sealer to expand and contract, causing cracks/peels.
In summary, polyurethane offers superior durability and protection, making it the better choice for high-use and outdoor applications. Lacquer provides a beautiful, glossy finish and is easier to repair, making it suitable for indoor furniture with lighter use.
In summary, acrylic paint is not entirely waterproof but does offer some degree of water resistance once it dries. This means that while your artwork won't immediately wash away with a splash of water, it is still vulnerable to prolonged exposure to moisture.
QUIKRETE® Acrylic Concrete Cure & Seal dries to a clear, satin finish in about 1 hour. Drying time will be increased in cool weather.
These sealers are resistant to deterioration and damage as well as surface abrasions, peeling, cracking, chemical exposure, pitting, freeze-thaw cycles, and flaking.
Acrylic sealants typically dry within 24 hours, but like silicone, they can be influenced by environmental factors. For interior jobs, acrylic is ideal because it dries relatively quickly and is paintable once dry. Best practices: Avoid applying in damp or humid areas.
USES FOR ACRYLIC SEALANT
Since it is odourless and easily paintable, acrylic sealant is most commonly used to seal household joints, such as stairs, skirting boards and floorboards.
Water-based acrylic sealers do have some disadvantages though. They are not easy to remove. So you can't expect to just wash off the sealer with a garden hose if you make a mistake. These are chemically strong, durable coatings that water does not penetrate.

Shellac: The natural choice. This traditional finish comes from natural resins secreted by the lac bug. These secretions are collected and processed into flakes that dissolve in ethyl or denatured alcohol. You can also buy shellac premixed, it's slightly cheaper than polyurethane.
Minwax® Fast-Drying Polyurethane
It's one of the most durable coatings for wood protection against scratches, spills and more, and is a clear coat. It can be used on both finished and unfinished wood projects, and is available in a variety of sheens. The fast-drying formula allows for quick recoats in 3-4 hours.
