High-performance Floor Reinforcing Primer

High-Performance Floor Reinforcing Primer for Concrete Floors — Deep Penetration, Strong Adhesion, Fast Application

High-Performance Floor Reinforcing Primer by JOSME is a polymer emulsion-based interface treatment material for floor substrate consolidation. It penetrates capillary pores of concrete, aerated concrete and plaster layers, locks loose cement particles and seals micro-pores to form stable and firm floor base layers. With a coverage rate of 0.1–0.15 kg/㎡ per coat, it supports large-area construction. The tinted formula helps construction teams distinguish treated areas effectively, avoiding missing spots during on-site operation.

What Is Floor Reinforcing Primer and Why Does Your Floor Need It?

Concrete floors that appear intact still contain abundant micro-pores and weak base layers. Long-term pedestrian load, tile laying construction and mechanical pressure will lead to substrate delamination, surface dusting and topcoat peeling.

High-Performance Floor Reinforcing Primer acts as a professional substrate consolidant. It treats loose and powdery floor surfaces to form stable base conditions for subsequent tiling, waterproofing and self-leveling construction. The product solves common floor base problems including loose particle falling, poor interlayer adhesion and substrate outgassing that causes pinhole defects on finished surfaces.

Technical Specifications

Key High-performance Floor Reinforcing Primer Features

Deep Penetration into the Substrate: Low viscosity polymer emulsion penetrates deep into the capillary pores and does not produce a film on the surface. Binds loose interior particles. Improves compactness and stability of floor

Full-coverage tinted formula: The colour layer makes it easy to manage coverage – perfect for large-area commercial floor construction and consistent spraying.

Optimised Interface Bonding: Seals surface micro-pores and consolidates loose base layers to provide certified bonding surfaces for tile glue, waterproof membranes and floor coatings.

Easy Construction Process Direct brush application requires no complicated mixing or special equipment, reducing processes and cutting on-site labour cost.

Dust and Sand Locking: Fixes loose cement particles on powdery floors, seals sources of dust from the surface; creates a clean and stable surface for future floor decorating.

Where to Use This Primer

This primer is intended for many floor preparation applications:

Concrete floor tiling, waterproofing and decorative coating pretreatment

Porous, weakly aerated concrete and plaster layer floors consolidation

Dust sealing and particle fixing of loose sandlime floor

Reinforcement of the interface for base layers prior to waterproofing.

Base reinforcement for floor priming before adding tiles

Carbonation, surface erosion and dusting – Industrial and commercial flooring base refurbishment

How to Apply

Substrate Preparation: Remove surface loose debris, oil stains and accumulated water to ensure clean and dry base before construction.

Construction Operation: Apply evenly on the floor surface with brushes or rollers.

Multi-Coat Treatment: For floors with severe sanding and dusting, apply two thin coats. Ensure full penetration of each coat before secondary construction.

Curing Treatment: Wait for complete curing of the primer before carrying out tile laying, waterproofing and subsequent floor construction.

Follow-Up Construction: After full curing, tile adhesive and other floor materials can be constructed normally.

Storage Tips: Seal the High-performance Floor Reinforcing Primer tightly and store in a cool and dry environment at 5°C–35°C when not in use.

Frequently Asked Questions

Q1: Can floor primer and wall primer be used interchangeably?

A1: Interchangeable use is not recommended. This floor-specific primer is designed for floor load and sand-sealing demands, while wall primer adapts to vertical substrate construction. The two products have different performance orientations.

Q2: Is one coat enough for slightly sanding cement floors?

A2: One coat can improve light floor sanding and dusting. For obvious sanding conditions, two thin coats are recommended for better particle locking and sealing effects.

Q3: Will the colored primer affect subsequent floor and tile construction?

A3: No. The color only serves to mark construction areas and avoid missing spots. It will not affect the bonding and use effect of subsequent tile adhesive and floor materials after curing.

Q4: Is primer necessary for visually solid concrete floors?

A4: Visually intact concrete still has micro-pores and weak base layers. Long-term load will cause outgassing and bonding failure. Primer pretreatment can eliminate hidden dangers of base layers in advance.
