- Sustainable Resource Use: Water-based low-VOC polyurethanes often require less energy to produce and apply, and their cleanup process typically involves water rather than harsh chemicals, reducing environmental contamination.
- Waste Minimization: Many low VOC products come in recyclable packaging, and their longer lifespan can lead to less frequent reapplications, thereby reducing material consumption over time.
How Durable Is Low VOC Polyurethane Compared to Traditional Finishes for Decks and Floors?
A common concern is whether low-VOC finishes can match the durability of traditional high-VOC products. Advancements in formulation have led to low VOC polyurethanes that offer excellent durability, including:
- Scratch and Abrasion Resistance: Many low VOC finishes provide a hard, protective layer that withstands daily wear and tear, making them suitable for high-traffic areas.
- Moisture Resistance: These finishes often repel water effectively, preventing damage from spills or humidity, which is crucial for both decks and interior floors.
- UV Protection: Some low VOC UV protective finishes contain UV blockers that prevent the sun’s rays from degrading surfaces or causing discoloration, thereby extending the life of outdoor decks.
It’s important to note that while low VOC finishes have improved significantly, their performance can vary between products. Selecting a high-quality polyurethane product and following the manufacturer’s application guidelines will help ensure optimal durability.
Can Low VOC Polyurethane Be Used on Both Wood and Concrete Surfaces?
Low VOC floor finish polyurethane formulas are versatile and can be applied to wood and concrete surfaces. Their adaptability makes them suitable for a variety of applications:
- Wood Surfaces: UV protective finishes enhance the natural grain on decks and hardwood floors and provide a barrier against scratches, moisture, and UV damage.
- Concrete Surfaces: When applied to concrete floors, these finishes offer a durable, easy-to-clean surface that resists staining and wear, making them ideal for basements, garages, and commercial spaces especially in conjunction with other coatings.
Before application, it’s essential to ensure the surface is properly prepared, and the specific product is suitable for the intended material. Consulting with a professional can provide guidance tailored to your project’s needs.
What Are the Application Steps for Low VOC Polyurethane on Decks and Floors?
Applying low VOC polyurethane to commercial decks and floors requires careful preparation to ensure a durable, long-lasting finish.
Here is a detailed step-by-step guide for applying low VOC polyurethane on commercial property surfaces with options for different surfaces:
Step 1: Prepare the Surface
A clean, smooth surface is essential for strong adhesion.
- Wood Surfaces: Sweep and sand with 120–150 grit sandpaper to remove old finishes and rough spots. Fill cracks with wood filler.
- Concrete Floors: Clean thoroughly with a pH-neutral cleaner and remove oil stains. If the surface is too smooth, etch it lightly to improve adhesion.
- Remove Dust: Vacuum and wipe with a tack cloth to eliminate fine particles before coating.
Step 2: Select the Right Low VOC Polyurethane
Choose from the suitable finishes from the following:
- Water-based polyurethane for faster drying and low odor.
- Oil-modified polyurethane for deeper penetration and extra durability.
- UV-protective finishes for outdoor decks or sun-exposed areas.
Step 3: Apply the First Coat
For even coverage, use a roller, brush, or T-bar applicator. Apply the finish using thin, even layers. Avoid puddles or thick spots that could cause peeling. Make sure to apply the finish following the grain or texture of the surface. Allow for proper ventilation to speed up drying.
Instructions for Medium- to Heavy Traffic Areas:
Apply a low-VOC polyurethane glaze using a roller, brush, or spray method to achieve a 0.4 millimeter film thickness. Allow this initial coat to cure overnight. Repeat the process for a second and a third coating. Note that the sanding and curing process should be repeated as many days as directed on the product label or manufacturer instructions.
Instructions for Light Traffic Areas Areas:
When applying eco-friendly finishes on low-traffic areas, apply polyurethane coating uniformly, aiming for a film thickness of approximately 0.63 centimeters. Take care to apply the coating evenly to prevent the formation of air pockets or pinholes. Once the initial coating has been set, apply a low-VOC glaze using a roller, brush, or spray method to achieve a 0.4-millimeter film thickness. After that, follow the sand and broadcasting instructions below.
Step 4: Dry & Sand Between Coats
The drying time varies depending on the type of finish you’re using. Consider the following recommended curing times:
- Water-Based Polyurethane: 2 to 4 hours to cure before recoating.
- Oil-Modified Polyurethane: 8 to 12 hours before recoating.
After curing, apply some light sanding. Use 320–400 grit sandpaper between coats to remove imperfections. Wipe the dust away before applying the next layer.
Step 5: Apply Additional Coats
For maximum durability, commercial floors require at least two to three coats. Follow the same process described above for the succeeding coats.
Step 6: Curing and Post-Application Care
The curing time varies for the final coat. Certain factors will come into play before the surface will be ready for use, which include the following:
- Light Foot Traffic Surfaces: Allow 24 hours of curing time after the final coat.
- For Furniture Placement: Wait 48 to 72 hours before setting heavy objects on newly coated surfaces.
- Full Cure: It will take seven to 10 days before the finish will be fully cured and ready for heavy commercial use.
Note: Cover the surface with temporary protection like rosin paper to prevent early wear.
Is Low VOC Polyurethane Safe for Pets and Children After Application?
