Left exposed to environmental forces, even the toughest structural materials will eventually degrade. Moisture seeps into concrete, triggering internal cracking; oxygen attacks bare iron, creating destructive rust; and solar radiation splits and rots structural timber. Protective coatings and industrial sealants act as an advanced chemical shield, intercepting these elements before they can cause permanent structural harm. At THS Now, we supply high-performance, contractor-grade formulations designed to molecularly bond with your surfaces, creating an impenetrable barrier against moisture, chemicals, abrasion, and extreme weathering.
The application process highlights how a liquid protective coating wraps seamlessly around a substrate. Once cured, this liquid layer transforms into a tough, continuous polymer membrane that completely seals out water, oil spills, and high foot traffic.

How to Select the Right Protective Sealant
Using an incompatible sealant or coating often leads to delamination, peeling, or premature material failure. To ensure maximum durability, evaluate these essential application parameters:
1. Surface Compatibility (Metal, Wood, Concrete)
Every substrate possesses unique physical characteristics that dictate chemical compatibility. Concrete is highly porous and naturally alkaline, requiring breathable, elastomeric membranes or deep-penetrating silane-siloxane sealers that can tolerate moisture movement. Metals require dense, non-porous formulations like epoxies or polyurethanes infused with active corrosion inhibitors to block oxidation. Wood requires highly flexible, vapor-permeable finishes that expand and contract naturally as the wood fibers absorb and release atmospheric humidity.
2. Chemical and UV Resistance Levels
If your surfaces are located in industrial workshops, commercial garages, or manufacturing facilities, they will likely encounter aggressive solvents, motor oils, hydraulic fluids, and acidic cleansers. For these harsh indoor setups, heavy-duty epoxy or polyaspartic coatings are ideal. For outdoor applications, however, intense ultraviolet (UV) radiation is the primary threat. Standard epoxies will chalk, yellow, and break down under direct sunlight; therefore, outdoor surfaces must be finished with aliphatic polyurethanes or specialized acrylic sealers engineered to resist UV degradation.
3. Indoor vs. Outdoor Application Needs
Indoor projects demand coatings with low VOC (Volatile Organic Compound) levels and minimal chemical odor to maintain safe air quality during application and curing. Outdoor projects, by contrast, prioritize rapid moisture resistance and broad thermal flexibility, enabling the coating to withstand unexpected rainfall shortly after application and endure seasonal temperature shifts without cracking.

Anti-Corrosive Metal Coatings: Formulated to stop structural rust in its tracks. Our anti-corrosive paints and aerosol sprays coat metallic surfaces with a high-density polymer barrier or a sacrificial zinc layer. They prevent moisture and airborne salts from triggering galvanic corrosion, making them perfect for structural steel framing, automotive underbodies, and industrial pipe networks.
-
Clear Wood & Deck Sealers: Preserve the rich, organic beauty of your timber without hiding the natural grain. These clear sealers penetrate deep into wood pores, forming a hydrophobic layer that sheds water effortlessly. By preventing deep water absorption, they eliminate common wood failures such as warping, splitting, checking, and fungal rot.
-
Concrete & Masonry Sealants: Keep your mineral-based structures clean and dry. Our advanced masonry sealers block liquid water absorption while remaining completely vapor-permeable, allowing internal concrete dampness to escape safely. This stops freeze-thaw cracking, limits ugly white efflorescence stains, and prevents moss or mold from anchoring inside your walls.
-
High-Heat Resistant Coatings: Standard decorative paints blister, smoke, and peel away when exposed to high operating temperatures. Our high-heat coatings are formulated with premium silicone resins and specialized pigments that maintain absolute structural and color stability at sustained temperatures up to 600°C. They are essential for industrial boilers, exhaust pipes, chimneys, and furnace doors.

Frequently Asked Questions
How often should I reapply a protective coating?
The reapplication schedule depends heavily on environmental exposure and physical wear. Exterior wood decks and high-traffic concrete driveways typically require a fresh maintenance coat every 2 to 4 years due to continuous abrasion and weather exposure. High-performance industrial coatings, such as multi-layer epoxy or polyurethane systems applied on structural metal or interior factory floors, can easily last 8 to 12 years before requiring a full re-application.
Are these sealants safe for food-contact surfaces?
Most standard industrial-grade sealants and anti-rust coatings contain volatile solvents and chemical additives that are not safe for direct food contact. For applications like kitchen countertops, food-processing machinery, or potable water tanks, you must explicitly choose specialized coatings that are certified food-grade and fully compliant with FDA or equivalent non-toxic standards after curing.
Do anti-rust coatings require a primer before application?
For optimal, long-term protection, applying a dedicated anti-corrosive primer is highly recommended. The primer chemically bites into the bare metal substrate, creating a secure foundation for the topcoat while introducing active rust-inhibiting compounds. However, if you are looking for a faster workflow, we offer advanced Direct-to-Metal (DTM) coatings that combine primer and topcoat properties into a single, high-adhesion application.
Can these coatings be applied to damp surfaces?
The vast majority of standard solvent-based and acrylic coatings require a completely dry substrate to bond effectively; applying them over dampness traps water underneath, leading to bubbles, blisters, and total adhesion failure. If you must work in damp conditions, you must select specialized moisture-cure polyurethanes or damp-tolerant epoxy coatings engineered to cure properly in the presence of surface moisture.
