DEFIX Salt Resistant DS-01 Paint – Effective Solution for Efflorescence and Alkali Attack on Walls and Concrete
Many constructions show patchy white streaks, peeling paint, blistering, or discoloration on walls and concrete floors shortly after completion. This phenomenon is efflorescence and alkali attack – one of the common causes of reduced lifespan for paint systems, especially in high-humidity areas or coastal constructions.
Many people choose to repaint surfaces without addressing the root cause. As a result, peeling recurs within a few months, leading to costly repairs and significantly impacting the aesthetic appeal of the structure.
To remedy this situation, using a specialized primer with salt and alkali resistance, and moisture barrier properties, is an essential solution before applying finishing coats. DEFIX Salt Resistant DS-01 was developed to meet this exact requirement, helping to create a durable base for the entire paint system.
What is DEFIX Salt Resistant DS-01?
DEFIX Salt Resistant DS-01 is a specialized two-component primer designed to treat surfaces affected by efflorescence and alkali attack before applying topcoats. The product can limit moisture from within the substrate, prevent salt crystallization, and enhance adhesion between the substrate and the finishing coat.
Not only suitable for new constructions, DS-01 is also an effective solution for renovating degraded structures due to the impact of humidity, salt, and alkali in concrete or cement mortar.
Why use salt-resistant paint before applying topcoat?
Concrete and cement mortar always contain natural alkali. When moisture moves from the inside out, dissolved salts travel with the water to the surface and crystallize, forming a white powder layer. This process reduces the adhesion of the paint layer, making the paint film prone to peeling, cracking, or blistering.
If only the surface is treated without controlling the internal moisture and salt sources, this phenomenon will continue to occur.
DEFIX Salt Resistant DS-01 acts as an intermediate protective layer, helping to:
- Prevent efflorescence and alkali attack.
- Limit moisture from concrete substrates.
- Reinforce the surface before topcoating.
- Increase the long-term durability of the entire paint system.
- Reduce future maintenance and repair costs.
Outstanding advantages of DEFIX Salt Resistant DS-01
The difference of DEFIX DS-01 lies in its ability to simultaneously address multiple causes of paint damage, rather than just acting as a conventional primer.
The product offers many advantages such as:
- Superior salt and alkali resistance.
- Prevents moisture渗透 from concrete substrates.
- High adhesion to various types of surfaces.
- Reinforces and stabilizes the substrate before topcoating.
- Extends the lifespan of the paint system.
- Compatible with various paint systems such as Epoxy, Polyurethane (PU), Acrylic, and other coatings.
- Suitable for both civil and industrial constructions.
Thanks to these characteristics, DS-01 helps minimize early peeling, especially in constructions with harsh environmental conditions.
Practical applications of DEFIX Salt Resistant DS-01
DEFIX Salt Resistant DS-01 is applied on various substrates such as concrete, plaster, bricks, and medium-load bearing floor surfaces.
The product is especially suitable for the following cases:
- Treatment of efflorescence on concrete walls.
- Remediation of alkali attack on concrete ceilings.
- Priming for new or old cement mortar surfaces.
- Reinforcing efflorescence-affected concrete blocks and fired bricks.
- Increasing moisture resistance for substrates before topcoating.
- Protecting concrete floors in factories and medium-load bearing areas.
- Renovating old constructions degraded by humidity.
- Coastal constructions where there is high salt content in the air.
- Factories, basements, areas frequently exposed to moisture and humid environments.
Key technical specifications
DEFIX Salt Resistant DS-01 is manufactured as a clear liquid paint, packaged in 1L and 4L kits.
Some notable specifications include:
- Mixing ratio A:B = 3:1 by volume.
- Pot life after mixing is 5 hours.
- Theoretical coverage of approximately 8–12 m²/liter/coat.
- Resistant to 5% NaCl solution for 24 hours without peeling or blistering.
- Resistant to 5% NaOH solution.
- Resistant to 5% H₂SO₄ solution.
- Density of approximately 0.92 kg/L.
- Shelf life of up to 24 months when stored correctly.
These specifications show that DS-01 not only resists salt but also has mild chemical resistance, meeting the requirements for substrate protection in various environments.
Application instructions for DEFIX Salt Resistant DS-01
For optimal effectiveness, the surface must be cleaned of dust, grease, mold, and other impurities. The substrate moisture content should not exceed 20% before application.
The application process includes:
- Stir each component separately.
- Mix component B into A at a 3:1 ratio.
- Stir continuously for about 5 minutes until homogeneous.
- Let the mixture rest for about 10 minutes before use.
- Apply with a roller, brush, spray gun, or rubber squeegee.
- Apply evenly to the surface according to technical specifications.
At approximately 23°C:
- Surface dry after 4–7 hours.
- Next coat can be applied after 8–12 hours.
- Fully cured after about 7 days.
Adhering to the correct procedure will help the primer maximize its salt resistance and enhance the durability of the paint system.
Why choose DEFIX Salt Resistant DS-01?
In fact, many paint peeling incidents do not stem from the quality of the topcoat but from improper substrate preparation. DEFIX Salt Resistant DS-01 helps address the root cause from the outset by stabilizing the substrate, controlling moisture, and limiting efflorescence.
This is a suitable choice for:
- Project owners who want to extend the lifespan of their construction.
- Contractors needing a professional substrate treatment solution.
- Factories, warehouses, basements.
- Coastal constructions.
- Renovation projects with persistent efflorescence and alkali attack.
The product is also compatible with various topcoat systems, optimizing the application process and increasing long-term effectiveness.
Conclusion
Efflorescence and alkali attack are subtle but significant causes affecting the lifespan of finished paint layers. Proper substrate treatment using DEFIX Salt Resistant DS-01 will help limit moisture, prevent salt and alkali, enhance adhesion, and extend the lifespan of the entire paint system.
If you are looking for a professional substrate treatment solution for new constructions or renovations, DEFIX Salt Resistant DS-01 is a reliable choice to protect surfaces durably over time.
