Wall Reinforcing Primer for Concrete & Masonry Substrates — Deep Penetration, Strong Bonding
The Wall Reinforcing Primer by JOSME is formulated with a refined composition of deionised water, functional additives, and a special polymer emulsion. It binds internal loose particles, forms stable base conditions for succeeding coating construction, and penetrates micro-pores on concrete, aerated concrete, plaster layer, and brick-concrete wall surfaces. The product provides consistent coverage efficiency with a standard dosage of 0.1–0.15 kg/㎡ per coat. It is a fundamental substrate pretreatment material for standard coating construction, and it is suitable for daily residential renovation and large-scale engineering construction projects.
What Is Wall Reinforcing Primer and Why Does It Matter?
Loose, pulverised, and porous substrates are the primary causes of coating system failure. Placing tiles, waterproof layers, and putty directly on untreated unstable walls will lead to delamination, peeling, and hollowing, which will result in project schedule delays and rework costs.
As opposed to its straightforward surface film formation, Wall Reinforcing Primer is distinguished by its profound capillary penetration. The consolidation of dispersed materials from the inside to the outside is facilitated by the infiltration of substrate micro-pores by ultra-fine polymer particles, resulting in the formation of stable base layers that facilitate the reliable bonding of consecutive construction layers.
It addresses common substrate issues that arise on-site, including surface chalking, irregular water absorption, and insufficient interlayer bonding.

Key Product Features
Uniform Coverage with Visible Colour: The tinted formula effectively delineates construction zones, thereby preventing the omission of any areas.
Low-Viscosity Deep Penetration: Capillary action consolidates scattered internal particles by penetrating mortar substrates over 3 mm deep.
Enhanced Substrate Pull-Off Strength: Improves bonding strength and resists delamination from moisture, temperature change, and friction after curing. The primer interface is not the source of damage, as per ISO 4624; rather, it is the substrate.
Flexible Construction Compatibility: This product is compatible with roller and brush, which simplifies the procedure and equipment required on-site.
Formula for Alkali Resistance: Long-term preservation of coating structure in alkaline cement and lime substrates at pH 8.0–9.5. It is steadfast.
Where to Use This Product
Concrete Surface Pre-Treatment Prior to Puttying: Improves the sifting and flaking of aerated concrete walls and concrete.
Prior to painting or puttingtying brick-concrete walls, micro-cracks and powdering are used to reinforce aged plaster.
Loose Sand-Lime Wall Pretreatment: Improves compactness to enable stable bonding with tile adhesive and waterproof layers.
Old Building Renovation: Rebinds free particles in friable gypsum and lime walls to stabilise basal layers.
It reduces efflorescence and inhibits soluble salt migration in humid, saline-alkali environments.
It is especially pertinent in coastal regions and areas with high humidity.
Quality Control
Full-process group quality control is implemented by JOSME:
Inspection of raw materials prior to production to confirm the qualification of the polymer emulsion
Formula stability is guarantyd through real-time parameter monitoring during production.
Adhesion, penetration depth, and alkali resistance testing of the completed product prior to delivery
ISO 4624 is adhered to by all adhesion tests. Consistent colour, particle state, and construction performance are guarantyd for large-scale orders through batch sample retention.
The factory is certified with ISO 9001, ISO 14001, ISO 45001, and ISO 50001, as well as China Environmental Labelling and China Green Wall Reinforcing Primer Certification.
Customization and Supply
JOSME provides standardized supply and customized supporting services for B-end customers. Standard in-stock products are delivered within 2–3 working days. Custom formula and private-label orders are completed within 7–15 working days.
Available customized items include different packaging specifications, private-label labeling, targeted formula adjustment for special substrates, and color matching for construction identification.
Large-scale project orders support advance scheduling. All business inquiries will be replied within 1–2 hours on working days.
Packaging
All products adopt export-grade reinforced packaging, which adapts to ocean freight transportation and avoids leakage, packaging damage and product failure during long-distance transit. Complete export supporting documents can be provided for cross-border orders.
FAQ
Q1: Will the tinted primer affect subsequent putty and decorative finish effects?
A1: No. The color only serves as a visual auxiliary mark for construction coverage. After complete drying, the surface putty and finish topcoat will fully cover the primer color without affecting the final wall decoration effect.
Q2: Why is primer necessary before tiling on sand-lime walls?
A2: Sand-lime substrates are loose in texture. Direct tile laying without pretreatment will cause hollowing and tile peeling in later use. Primer penetration and curing improve substrate cohesion and provide reliable bonding bases for tile adhesive.
Q3: How does the product’s coverage rate control project costs?
A3: The standard dosage of 0.1–0.15 kg/㎡ realizes high coverage per unit material. It controls overall material costs, and the simple construction method also shortens substrate pretreatment cycle and saves on-site labor costs.
Q4: Can this primer reduce topcoat consumption?
A4: Yes. It seals substrate pores and balances surface water absorption, avoiding uneven topcoat penetration caused by porous substrates, so as to reduce waste of subsequent finish materials.
