PC-Prime® DLS

Advanced Alkali-Resistant Deep Penetration Primerfor Stronger, Longer-Lasting Coatings

PACKAGING

PC-Prime® DLS is supplied in 20 kg air-tight buckets,
ensuring safe storage, protection from contamination,
and preservation of product quality during handling and
transportation.

PC-Prime® DLS is a high-performance, water-based acrylic copolymer primer designed to deeply penetrate and seal porous substrates while providing superior resistance against alkali attack. Engineered for both interior and exterior applications, it strengthens weak surfaces, enhances adhesion of subsequent coatings, and ensures long-term durability of finishing systems. Its excellent bonding capability and substrate consolidation properties make it an ideal base coat for modern construction and renovation projects, delivering a uniform and stable foundation for decorative and protective coatings.

FEATURES

Deep penetration into porous and weak substrates
Excellent adhesion for subsequent coatings
Strong resistance to alkali attack
Improves durability of paint systems
Reduces surface porosity and dusting
Water-based and low VOC formulation
Easy application by brush, roller, or spray

USES

Exterior and interior wall priming
Concrete and cement plaster surfaces
Block work and rendered substrates
Gypsum board preparation
Renovation of old and chalky surfaces
As a base coat before waterproofing or paint systems

SURFACE PREPARATION

All surfaces must be structurally sound, clean, dry, and free from dust, oil, grease, laitance, curing compounds, or any contaminants that may affect adhesion. Loose or weak materials should be removed, and surface defects such as cracks, pinholes, or undulations must be repaired prior to application. A light sanding is recommended to improve surface profile and ensure proper bonding. After preparation, all dust and loose particles
must be thoroughly cleaned before applying PC-Prime® DLS.

CONDITIONS DURING APPLICATION

Application of PC-Prime® DLS should be carried out when the substrate temperature is above 10°C and at least 3°C higher than the surrounding dew point to prevent condensation on the surface. The substrate must remain dry during application. Proper ventilation is essential, particularly in confined or enclosed areas, to ensure adequate drying and film formation. Avoid application under extreme humidity, direct rain exposure, or strong wind conditions, as these may adversely affect performance and final finish.

DRYING TIMES

Drying time of PC-Prime® DLS is influenced by ambient temperature, relative humidity, air circulation, film thickness, and number of coats applied. Under standard conditions (approximately 23°C and 50% relative humidity), the coating becomes touch dry in about 3 hours and achieves sufficient
hardness within 5–10 hours. Recoating can typically be done after a minimum interval of 3–6 hours. At lower temperatures, drying will be slower, while higher temperatures will accelerate the drying process. It is essential that the surface is completely dry and free from contaminants before applying subsequent coats.

RECOMMENDED PAINT SYSTEM

PC-Prime® DLS is recommended as a single coat primer applied over properly prepared substrates to provide a strong and stable base. It should be followed by two coats of suitable topcoat such as exterior or interior decorative paints, elastomeric coatings, or waterproofing systems depending on the project requirements. The primer enhances adhesion and ensures better performance and
durability of the complete coating system.
