When it comes to getting a good and long-lasting acrylic finish, the secret is hidden beneath the surface. Meet AcrylUnder, a high-performance acrylic primer designed to prepare and protect surfaces before applying topcoats. Whether you’re doing a DIY project at home or working on a large-scale commercial project, AcrylUnder ensures that your final coat not only looks good but also lasts longer.
What is AcrylUnder?
AcrylUnder is a water-based acrylic primer that provides a durable, receptive base for a variety of acrylic coatings. It is commonly applied to masonry, cement plaster, gypsum board, fibre cement, and previously painted surfaces. Its short drying time, excellent adhesive properties, and ease of application make it a popular choice among professionals and homeowners.
What distinguishes AcrylUnder is its ability to seal porous surfaces and improve adhesion while maintaining breathability and flexibility. This makes it excellent for surfaces that may expand or contract in response to temperature or humidity fluctuations.
Benefits of Using AcrylUnder
1. Excellent Adhesion
AcrylUnder greatly improves the connection between the surface and the final acrylic coat. This means less possibility of peeling or flaking over time.
2. Seals porous surfaces
Unsealed substrates absorb topcoat unevenly. AcrylUnder prevents this by filling and sealing pores, allowing your topcoat to spread more evenly and extend further.
3. Quick Drying
In most circumstances, AcrylUnder dries to the touch in less than an hour, allowing for same-day overcoating and faster project completion.
4. Easy to apply
AcrylUnder can be applied using a brush, roller, or spray gun, depending on the surface and your level of comfort. Its silky consistency minimises splatter and leak.
5. Improves durability
Using AcrylUnder as a primer extends the life of your topcoat, lowering maintenance expenses and repainting frequency in the long run.
Where and When to Use AcrylUnder
AcrylUnder is appropriate for both indoor and outdoor applications. It works well on surfaces that will be completed with water-based acrylic paints. Common application areas include the following:
- Cement plaster walls
- Gypsum ceilings
- Fibre cement boards
- Previously painted, but sound surfaces
- New concrete surfaces that have cured completely
Before using AcrylUnder, ensure that the surface is clean, dry, and free of dust, grease, and loose particles. If the surface contains mould or algae, it should be treated with a biocide first.
Application Tips
- To achieve a uniform consistency, thoroughly stir before use.
- To achieve the greatest results, use a synthetic bristle brush or a medium-piled roller.
- Do not use in damp areas or if rain is forecast within 4-6 hours.
- Depending on the temperature and humidity, wait at least 1 hour before applying a second or top coat.
How much do you need?
AcrylUnder covers 8-10 square metres per litre per coat, depending on the porosity of the substrate. One layer is usually enough for priming, but more porous surfaces may require two coats for a firmer seal.
Environmental and Safety Considerations
AcrylUnder contains minimal levels of VOCs (volatile organic compounds), making it safer for indoor use and more environmentally friendly. It is also nonflammable, water-based, and simple to clean with soap and water. However, use only in well-ventilated spaces and prevent contact with the skin and eyes.
Frequently Asked Questions About AcrylUnder
Is AcrylUnder OK for external walls?
Yes, AcrylUnder is meant to be long-lasting and weather-resistant, making it appropriate for both indoor and outdoor uses.
Can it be used over oil-based paints?
No, AcrylUnder is designed for use in water-based systems. If painting over oil-based coatings, use an appropriate bonding primer instead.
Should I sand the surface before applying AcrylUnder?
If the surface is glossy or has defects, it is recommended that you sand it lightly. Simply ensure that any new, rough surfaces, such as plaster or cement, are clean and dry.
Can I tint AcrylUnder?
Yes, AcrylUnder can be coloured to match the topcoat. This improves colour coverage while reducing the number of topcoat layers required.
How long until I can paint over it?
AcrylUnder dries to the touch in 30-60 minutes, but waiting 2-4 hours before applying the topcoat yields the greatest effects.
Is it safe for use around dogs or children?
Once dried, it is perfectly harmless. While applying, maintain adequate ventilation and keep pets and children away until the area is dry.
