What is a Primer?
Premium primers are expertly formulated base coats designed to optimize adhesion, enhance surface uniformity, and ensure long-lasting performance of topcoats. Engineered with high-quality resins and specialty additives, they penetrate deeply, seal effectively, and prepare a wide range of substrates—from porous masonry to previously coated surfaces. Whether it's silicate for breathability, quartz for texture grip, or isolating primers for stain-blocking, these advanced formulations deliver reliable results across both residential and commercial applications. Trusted by professionals, premium primers promote durability, minimize surface imperfections, and elevate the overall finish, making them an essential foundation for any superior paint system.

Primers That Do More Than Prepare
Seal, Strengthen, and Set the Stage for a Flawless Finish
01
Hydrophobic Primer
Hydrophobic primers with surface strengthening properties are ideal for preparing and protecting exterior mineral surfaces. Products like Remmers Primer Hydro HF, Primer Hydro SF, Primer Hydro S HF, and Earthborn Silicate Primer penetrate deeply to consolidate substrates while creating a water-repellent barrier. These advanced formulations enhance adhesion, reduce water absorption, and increase the durability of topcoats. Highly breathable yet moisture-resistant, they help prevent issues like efflorescence, mold, and frost damage—making them a smart choice for long-term surface protection in demanding environments.
03
Wood Primer
Specialist wood primers such as Remmers Aqua AG-26, Sealing Primer, and Earthborn Multi Purpose Primer are designed to condition and protect timber surfaces, ensuring a smooth and durable foundation for topcoats. These primers penetrate and seal porous or uneven grain, minimizing tannin bleed and enhancing adhesion across both hardwoods and softwoods. Whether used on interior joinery or exterior woodwork, they promote even coverage, reduce patchiness, and extend the life of the final finish. Ideal for bare or previously coated timber, these versatile primers offer excellent sanding properties and moisture regulation, making them essential for a professional, long-lasting result.
02
Stain Blockers
High-performance stain-blocking primers like Classidur Xtreme Primer and Earthborn Isolating Primer are specifically designed to tackle challenging surfaces and persistent stains. Formulated to isolate and seal in water marks, nicotine, smoke damage, and other discolorations, these primers provide a clean, stable base for topcoats. Their quick-drying, low-odour formulas make them ideal for both renovation projects and sensitive environments. With excellent adhesion and long-term sealing power, these primers ensure stains don’t bleed through, delivering a flawless, lasting finish on even the most problematic substrates.
04
Textured Render Primer
Textured primers such as Remmers Quartz Primer are specially formulated to create an ideal bonding surface on render and other mineral substrates. Infused with fine quartz aggregates, this primer provides a subtle grit that enhances mechanical adhesion for subsequent coatings, ensuring maximum grip and uniform application. Perfect for use under mineral and synthetic renders or paints, it also helps to regulate absorption, reducing patchiness and improving overall coverage. Whether on new builds or renovation projects, textured primers offer superior surface preparation for a more durable, long-lasting finish on exterior facades.
Where do I need Primer?
Stone. Brick. Render. Concrete. Wood. Metal. Plastic
Primer is essential wherever you need to seal, stabilize, or improve adhesion before painting. It's especially important on bare surfaces like new plaster, wood, or masonry, as well as on problematic areas such as stained walls, glossy finishes, or highly absorbent substrates. Using the right primer ensures a smoother, more even finish and helps topcoats last longer by preventing peeling, flaking, or discoloration over time.
Masonry & Render
Primers for masonry and rendered surfaces are key to achieving a durable, long-lasting exterior finish. High-performance options from brands like Remmers, Classidur and Earthborn improve adhesion, regulate surface absorption, and strengthen the substrate. They create a stable foundation that helps topcoats resist peeling, cracking, and weather-related wear—ensuring your home stays protected and looking its best for years to come.
Block Water & Fire Stains
Stain-blocking primers are essential for covering stubborn marks caused by water damage, smoke, fire, nicotine, and other tough stains. These powerful primers seal in discoloration and prevent it from bleeding through the topcoat, restoring surfaces to a clean, paint-ready state. Ideal for renovation and restoration projects, stain blockers like Classidur Xtreme and Earthborn Isolating Primer offer excellent coverage, fast drying, and long-lasting protection—making them the go-to solution for achieving a flawless finish on even the most damaged walls and ceilings.
Industrial Floor Coatings
Primers for concrete floors are a crucial first step when installing epoxy flooring systems. These specially formulated primers penetrate the concrete surface to seal pores, improve adhesion, and reduce the risk of bubbles or delamination. By creating a strong bond between the substrate and the epoxy topcoat, they enhance durability and ensure a smooth, long-lasting finish. Ideal for both residential garages and high-traffic commercial spaces, concrete primers help deliver a professional-grade floor that resists wear, chemicals, and moisture.
Wood Primers
Wood primers are specially designed to prepare timber surfaces for painting or staining, sealing the grain and promoting smooth, even coverage. They help prevent issues like tannin bleed, patchiness, and uneven absorption—especially on bare or knotty wood. Whether for interior joinery or exterior cladding, high-quality wood primers improve adhesion and durability, ensuring your topcoat looks great and lasts longer.
Universal Primers
Universal primers are versatile bonding agents formulated to stick to a wide variety of surfaces including metal, plastic, tile, glass, and glossy finishes. Ideal for tricky or mixed-material projects, they offer excellent adhesion where standard primers might fail. Fast-drying and easy to apply, these all-surface primers create a strong, reliable base that helps paint grip better and resist peeling—making them perfect for everything from upcycled furniture to industrial fixtures.
