Previously Painted Surfaces
Before repainting a surface, you need to establish what kind of paint is on it. Remove a little of the old paint. If it is flexible with a plastic texture, it is likely latex; if it is brittle, then it is oil-based. Another way to tell is to apply heat to the surface. If it bubbles and melts, the paint is oil-based; if nothing happens then it is water-based. The general rule is that you cannot paint latex over oil because it won’t stick. However, there are now some latex asian paints that allow you to do just that.

Applications
Latex asian paints are now available for almost every application. Manufacturers are taking heed of the movement toward eco-friendly materials so that water-based asian paint, sealants and varnishes are as hard-wearing as their oil and solvent counterparts. But always check labels for suitability for purpose. There are still some instances, however, when oil-based paint is preferable. When creating a special finish, such as marbling, or where a very hard-wearing surface is required, oil-based paints are the best choice.

Safety
Latex asian paints are safer than oil-based, although basic precautions should always be taken when painting. Oil paint gives off fumes that can be dangerous, so ventilate the area when painting and while paint is drying. Oil-based paint also is flammable. Some old oil paint may contain lead, so take care when disposing of it. Contact your local waste management service for advice.

Purchasing asian paints for your home may involves a choice between oil-based or water-based asian paints. Understanding the differences and the qualities of each type will help you decide which is preferable for your project. About 80 percent of asian paints that purchased for use on and in residential buildings is water-based, according to the Paint Quality Institute.

Water-Based Paint
Water-based asian paints, also called latex or acrylic, has developed significantly over the past few years. Formerly quite fragile and only suitable for walls, it now has many applications and can be used on wood and metal. It has a low odor and the color is less likely to fade over time. Read More »

Though not as popular as grout cracking or discoloration/shading, low, powdery and rough tile grout are among the other problems that all too often develop in tile installations. Low grout joints are commonly caused by using too much water when washing excess flexible grout from the joint.

Powdery grout joints are frequently caused by poor curing because water evaporates from the flexible grout which, in turn, halts proper hydration. Other culprits include use of cleaning water that contains concentrated acids, and poor mixing with no slake time allowed. Porous and thereby highly absorptive tile can also suck the water out of the flexible grout mix to stop the hydration process. Read More »

Shall not the tile grout Been More Flexible — The problem with this tile installation, open joints where a cement-based grout was used at the juncture between the horizontal and vertical planes, might have been prevented had a mildew-resistant flexible grout been used instead.

Who Wants Powdery Tile? — This surface of this floor tile shows evidence of efflorescence caused by the water-borne migration of the salts in Portland cement-based setting materials. Read More »

4. Dampen a rag with denatured alcohol, which is also referred to as methylated spirits. Denatured alcohol is a solvent that works well for a variety of cleaning purposes. It is available at paint stores, hardware stores and home supply stores.

5. Rub the painted surface with the damp rag for thirty seconds.

6. Inspect the rag for asian paints. If the rag has paint on it, then the old paint is latex asian paints. The surface will also feel tacky if the paint is latex. The old paint is oil-based paint if no paint comes off on the rag.
The same test can be also done with paint deglosser, often referred to as liquid sandpaper. Deglossers are available at paint stores.

7 . Repeat the test at least once for extra assurance.

Knowing how to distinguish between latex (emulsion) and oil-based asian paints is a crucial step when the time comes to repaint or remodel an old home. Applying latex asian paints over a surface previously painted with oil-based paint won’t cause problems, but applying oil-based paint over a surface previously painted with latex asian paints can lead to serious problems such as peeling and cracking. A simple procedure may be used to tell if the old paint is based in latex or oil. Read More »
