Another very popular method of painting here in Singapore is by rolling with a paint roller. This method of painting is usually employed for large flat
surfaces like our walls and ceilings and in marine applications on vessel hulls and decks. Rolling is fast and the finished result is better than brushing. But a point to note is that rolling does not always thoroughly wet the substrate. You may not achieve the dry film thickness you want by a single application. Types Of Roller Roller covers come in several different types of material. It can be made of lambswool, mohair, polyester, nylon, cotton etc. The more popular ones are the polyester and the mohair types. Recent years have seen an increased usage of flock rollers - short-naped mohair on a sponge core. These have the important advantage of not carrying too much paint which often causes dripping onto floors and splashing while rolling. Sizes Available 
Roller sizes that are common here are 2 inch, 4 inch, 6 inch and 7 inch. The picture on the right shows a 4-inch polyester roller. This type of roller is also known as radiator roller, while some call it “mini-roller”. These are very popular in industrial usage. 4-inch sized roller allow access into smaller or confined surfaces. For home painting, a 6-inch or a 7-inch roller would do well on walls and ceilings. The 4-inch types can be used for doors and gates. Which to Use? For all water-based paint jobs on walls and ceilings, I recommend the flock roller. I receive many good feedbacks from users. The polyester and mohair types can be used with solvent-based paints. The mohair rollers are especially useful for painting doors and gates. You can use mohair rollers for varnishing wooden furnitures and wooded decks.
