Leyland Trade Acrylic Primer Undercoat - White 2.5L

Product Information

As well as classifying these paints by chemical composition, they can also be divided into universal, plasterboard and cover-all types. Universal undercoat About the only time I could see where you'd want to prime over paint is if you wanted to paint over an oil based paint with an emulsion. In that case it would be a good idea to primer over the oil based paint with an oil based primer, and then apply the emulsion over the dry primer. Although most "universal" primers are intended for certain types of materials (such as tiles or plastics), more unusual materials such as PVC, laminate, cast iron or iron may need a specialized underlay to ensure good adhesion of subsequent coats of paint. Primers for wall tile / decorative plaster

Intended for use with emulsion paints, water-based undercoats are vital in many cases for a smooth finish. Most of the options within the UK will also function as a primer, effectively offering protection for the underlying material and an adhesive surface for painting in a single coat. Acrylic Primer Undercoat If the paint is chalking or is chipped, use an oil-based enamel undercoat primer after properly prepping the surface. As you've now seen, there are many varieties of undercoat (or primer), with prices varying from single well into double figures for the same quantity of product! These are the key criteria that differentiate the many varieties of primer. Opacifying powerThis is another type of water-based undercoat that will also include a primer. Depending on the brand it can be suitable for use on wood, masonry, and plaster. Undercoats for Wood Priming bare timber is essential for the success of the whole paint system. The primer soaks into the timber creating a good bond and quenches the absorbency. This provides a sound base for the next coating. Acrylic Primer Undercoat can be used both as a primer and full undercoat. Any of the Leyland finishes can be applied over the product, even solvent based gloss.

Alternatively, if your drywall is relatively smooth and the topcoat is going to be a flat paint, you can skip the primer and use two coats of high-quality self-priming water-based flat paint (see “Self-Priming Paints,” below). The heavy-bodied paint resins in self-priming paints seal the surface and fill imperfections (which are less visible in flat paint anyway).A measure of the paint's ability to smooth out surface irregularities. Of course, the effect will be limited - it's essential to prepare your walls (i.e. plaster etc.) before applying undercoat (only to be used on clean, dry, solid surfaces). Coverage No...definatly not..really..you should never use emulsion as an undercoat over previously painted gloss or satin finish. This type of paint is multi-purpose and renders the substrate uniform, concealing imperfections, and improves adhesion of the finishing paint. It also makes application and removal of other wall products easier, can be applied in any room (dry or wet) and can be covered over with any type of top coat (glycero or acrylic). It is best suited to interior surfaces in good condition. It provides strong adhesion on plaster, plasterboard, wood and cement, and gives economical coverage in large volumes. Plasterboard primer

An undercoat, as its name suggests, is the first layer of paint applied to a clean, dry substrate, before the finishing coat. Although it might be tempting to cut out this step - lazy as we are! - it really does make a big difference! Represents the surface area that can be covered per litre of product. This is important as it lets you calculate how much paint you'll need to buy. Just like with finishing paints, the greater the coverage, the less paint you need - so the more money you can save. Tips for choosing So… should I spend money on more expensive primer sealer or splash white matt emulsion all over instead? Removing the old paint first is too much work and therefore not an option…! Attempting to paint a room in your home? Have you been left bewildered by the different types of paint? You're not the only one. Before buying pots and pots of your dream colour, it'll save you a lot more money (and time) if you choose the right one, depending on what you need to paint. Oil-based undercoat paints are for use with oil-based finishing paints. While these paints were traditionally the choice of professionals, advances in water-based options mean that today many will use both, or have moved to water-based entirely. It’s worth keeping in mind that oil-based undercoat paints will release volatile organic compounds (VOCs) while drying, which can be dangerous. Ensuring adequate ventilation is crucial, with many opting to use water-based paints internally. Water-Based Undercoat

Introduction

Not all water based paints are the same..basically the typical make up of emulsion is powder (the pigment) and a binder/medium which hold the pigment together..otherwise it would just rub off as soon as you touched it..
