Buy Paint Sealer, Paint Primer & Undercoats Online

Choose your paint sealer or paint primer by the surface and its condition. A sealer controls absorption on porous materials, a primer helps paint adhere, and an undercoat provides a uniform base beneath the finish. Some products combine these functions.

Find preparation coatings for:
• Interior walls and ceilings
• Exterior masonry and repainting
• Metal gates, doors and railings
• Wooden furniture, cabinets and timber doors

Check approved surfaces, coverage per litre and topcoat compatibility before ordering. For combined primer sealer products, follow the specified coating sequence.

Sealer Paint for Walls & Ceilings

Sealer paint for walls helps control absorption on porous plaster, cement render and concrete. Apply a compatible wall sealer paint before the finishing coats to help reduce patchy coverage caused by uneven absorption.

Wall sealers are commonly used for:
• New plastered or cement-rendered walls
• Interior walls and ceilings
• Previously painted walls requiring sealing
• Exterior masonry approved for the selected product

Choose an alkali-resistant sealer where the masonry paint system requires it. For ceiling repainting, check whether the surface needs sealing or spot priming. Repair leaks, allow surfaces to dry and let new plaster or render cure before coating.

Primer Paint for Walls, Wood & Metal

Primer paint helps the next coat bond to the substrate. The right primer coating depends on whether you are painting masonry, timber, steel or a smooth surface that needs specialist adhesion.

Paint primers are useful for:
• Bare wood and exposed metal
• Patched walls and repaired areas
• Smooth surfaces needing an adhesion primer
• Surfaces requiring a consistent base before topcoating

For primer paint for walls, follow the recommended paint system. Porous masonry may need a wall sealer, while stained or difficult-to-coat areas may require a specialist wall primer.

Solvent-Based Sealer Paint for Masonry Walls

Solvent-based sealer paint is used where the masonry condition and recommended topcoat call for it. Depending on the formulation, it may offer alkali resistance or help bind residual chalkiness after surface preparation.

Suitable applications may include:
• New masonry requiring an alkali-resistant sealer
• Prepared walls with residual chalkiness
• Repainting over compatible existing coatings
• Approved interior or exterior masonry

Check the product specifications for surface treatment, thinning and recoating instructions. Powdery or chalky walls may need a dedicated treatment before painting.

Water-Based Sealer Paint for Interior Walls

Water-based sealer paint prepares porous walls and ceilings for compatible finishing coats. Many formulations offer low odour and water cleanup for convenient interior painting.

Water-based sealers can be suitable for:
• Interior walls and ceilings
• HDB flat and condominium repainting
• Residential and commercial interiors
• Projects specifying low-odour or low-VOC coatings

Confirm the individual product’s VOC information, drying times and approved surfaces. For outdoor walls, choose a formulation explicitly approved for exterior use.

Metal Primer Paint for Gates, Railings & Steel

Choose primer paint for metal that matches the metal type and exposure. An anti-corrosive metal primer paint helps protect properly prepared steel and iron against rust and provides a base for compatible finishing paint.

Use a suitable metal primer for:
• Steel gates and railings
• Metal doors and frames
• Machinery and equipment
• Outdoor steel structures

Remove loose rust, grease and flaking paint first. Galvanised steel, aluminium and other non-ferrous metals may need a specialist adhesion or etching primer. Use undercoat paint for metal only as part of the recommended coating system.

Wood Primer Paint for Timber & Furniture

Wood primer paint helps control absorption on bare timber and prepares it for an even painted finish. Choose a stain-blocking formulation where knots or tannin staining could show through the topcoat.

Use a suitable primer paint for wood on:
• Wooden furniture and shelving
• Timber doors and frames
• Cabinets and cupboards
• Timber panels and carpentry work

Sand and clean timber before priming. Match the wood primer to the finishing paint and interior or exterior exposure. For a clear or stained finish, check whether the system requires a wood sealer instead.

Undercoat Paint & Primer Sealer Undercoats

Undercoat paint creates an intermediate layer that helps improve coverage and colour uniformity. A combined primer sealer undercoat performs multiple preparation functions on approved surfaces.

These coatings may be suitable for:
• Prepared wood or metal, as specified
• Bare surfaces approved for a combined coating
• Repainting that needs a more uniform base
• Colour changes where an undercoat is recommended

An undercoat does not automatically replace a metal primer, stain blocker or other specialist primer. Follow the manufacturer’s recommended sequence.

How to Choose Paint Sealer, Primer & Undercoats

Before buying a sealer, primer or undercoat, check:
• Surface material: masonry, wood, steel or another metal
• Surface condition: bare, painted, chalky, stained or rusty
• Interior or exterior exposure
• Compatibility with the finishing paint

Compare sealer paint prices and primer prices alongside coverage, required coats and tin size. Estimate quantity from the area to be painted and the stated coverage per litre, allowing for surface porosity and application losses.

Paint Preparation for Singapore Homes & Projects

Choose wall sealers and primers in Singapore with the surface condition and application environment in mind. Humidity, ventilation and damp substrates can affect drying and adhesion.

Common projects include:
• HDB and condominium wall repainting
• Landed home interior and exterior painting
• Furniture and cabinet refurbishment
• Shop, office and industrial maintenance

Resolve moisture problems first. Allow the specified drying and recoating intervals before applying the next coat.

Benefits of Paint Sealers, Primers & Undercoats

A suitable preparation coating can help provide:
• Better adhesion between the substrate and finishing paint
• More consistent absorption on porous surfaces
• More even topcoat coverage and colour
• Better durability from the complete paint system

These benefits depend on correct surface preparation, compatible coatings and suitable application conditions.

How to Apply Paint Sealer & Primer

Before applying a paint sealer or primer:
• Remove dust, grease, loose paint and contaminants
• Repair defects and allow surfaces to dry or cure
• Stir and thin only as instructed
• Follow the specified coverage, coat thickness and recoating time

Apply with the recommended brush, roller or spray equipment. Maintain suitable ventilation during application and drying.

Frequently Asked Questions About Sealers, Primers & Undercoats

What is the difference between sealer paint and primer paint?
Sealer paint mainly controls absorption on porous surfaces. Primer paint promotes adhesion between the substrate and the next coat. An undercoat provides a uniform base for finishing. Some products combine these functions.

Do I need wall sealer paint before repainting?
New or porous masonry commonly needs a compatible wall sealer. Previously painted walls may need sealing or spot priming depending on their condition. Follow the selected paint system’s preparation instructions.

Is water-based or solvent-based sealer better?
Choose the formulation specified for your surface and topcoat. Water-based sealers often offer low odour and water cleanup. Solvent-based sealers may be specified for particular masonry conditions. Check the individual product’s properties.

Is sealer paint waterproof?
Standard wall sealer is a preparation coating and should not be assumed to waterproof a wall. Repair leaks or water ingress and use a specified waterproofing system where required.

Is paint sealer the same as paint sealant?
The terms can refer to different products. For wall painting, a sealer usually prepares porous masonry before topcoating. A sealant typically fills joints or gaps, while some protective finishes are also called paint sealants. Check the intended use before buying.

Which primer paint should I use for metal?
Use a compatible anti-corrosive primer for bare steel or iron. Aluminium and galvanised metal may require a specialist adhesion or etching primer. Confirm compatibility with both the metal and finishing coat.

Should I use wood primer before painting timber?
Bare timber generally needs a suitable wood primer unless the paint system specifies otherwise. Sound, previously painted wood may only need cleaning, sanding and spot priming. Use a stain-blocking primer where required.

How much does sealer paint or primer paint cost?
Prices vary by brand, formulation and pack size. Compare current sealer paint and primer paint prices in the product listings, including Nippon Paint options. Check coverage and required coats to estimate the cost for your project.

How long should I wait before painting over sealer or primer?
Follow the product’s specified recoating time. Drying varies with coating thickness, temperature, humidity and ventilation. A surface that feels dry may still need more time before topcoating.
