What is paint clabbering?
Clabbering/cream formation is the formation of a dry paint layer on the surface of the paint based on the type of the paint coming into contact inside the container via solvent volatilization or oxidation. Clabbering may occur especially in sealed packages with air leak or paint containers not sealed tightly after use. Crusty layer must be removed delicately and the paint must be mixed thoroughly during application.
What is loss of gloss?
Loss of gloss is the humidity condensing on the paint layer and causing a flat appearance when the paint is applied in weather conditions such as rain, frost and fog. High gloss paints applied on partially hardened primer may cause flat or semi-flat appearance; the desired gloss may not be achieved. Moreover, the paint may become flat after drying in an indoor area not sufficiently ventilated due to the evaporated solvent condensing on the paint film layer.
What is paint curtaining?
Paint curtaining is formation of a thicker layer by the paint on the external surfaces flowing downwards and causing the surface to lose its smoothness. The main reason is the thick application of the paint. Curtaining may occur in reduced paints and may be caused by excess humidity in the air, no ventilation or the variation between the temperature of the painted surface and the ambient temperature. To achieve the best result in painting applications, take a break from painting in humid weather.
What is paint bleeding?
Paint bleeding is the substrate paint becoming visible on the top layer as a result of applying two different colors of paints one after the other. The reason is that the paint applied on the upper layer reacting with and dissolving the pigments of the underlying paint. Paint bleeding usually occurs due to applying the topcoat paint before waiting for the primer to dry completely. The most efficient solution of this problem is to apply a primer over the old underlying paint which will not dissolve the pigments of such paint.
What is paint precipitation and phase separation?
Paint precipitation and phase separation is pigments and filling materials cumulating at the bottom of the paint container due to density and forming hard/soft sediment. Although Firacolor does not various additives to prevent such formation due to precipitation and phase separation like other paint producers, especially high density paints (primers) may precipitate in time. Storing the paint not longer than the specified storage period and storing at the recommended temperature specified in the application instructions will prevent such occurrence.
What is orange peel appearance in paint?
The primary reason for the surface having an orange peel appearance is due to the paint thinned by quick-volatile solvents, high application viscosity and inappropriate distance between the surface to be painted and the application tools such as guns. Paint dispersion may be achieved by adding a slow volatilizing solvent to the diluting thinner.
What is paint cracking?
Typically occurring in mechanical stresses due to temperature differences, cracking occurs when the paint exceeds the elasticity limit. Applying the top coat paint before waiting for the underlying paint to dry may lead to cracking as well.
What is paint chalking?
Paint chalking is the paint transforming into loose powder due to degradation of the surface binding agent or the underlying agent. When the binding agent loses its integrity on the paint surface due to temperature, UV beams or oxygen, pigments become easily peelable.
What is paint blistering?
Liquids and gasses available in/under the paint imposing a pressure greater than the adhesion strength of the paint may lead to blistering; the solution is to slowly increase the temperature.
What is paint peeling?
Peeling off of the paint due to paint losing its adhesion properties. The surface on which the paint will be applied must be free of water and oil in order to prevent such peeling.
What is paint wrinkling?
The orange peel appearance typically seen in oil-based paints is commonly caused by thick application of the paint. A uniform drying is not achieved in thick applications due to the air (oxygen) not penetrating the paint. The surface dries, however, the substrate drying is delayed and wrinkling occurs.
What is raised paint?
When a new layer is applied on top of a previously painted surface, the underlying paint is affected and blisters, wrinkles may occur or may get raised or partially peeled off. For instance, when a cellulosic based topcoat paint is applied over an alkyd resin based primer paint, the solvents in the cellulosic paint affects the film in the alkyd resin paint and causes to be raised. In order to prevent such occurrence, the solvents of the applied paint shall not affect the underlying paint.
What is paint insufficient covering?
Insufficient covering is due to inadequate opacity of the paint.
The reasons are;
- insufficiently mixed paint,
- excess thinning,
- spreading past the requirement,
- applying the topcoat without preparing the highly absorbent surfaces with the required putty / primer application and not applying sufficient number of paint layers to the surface.
Once the required surface preparation is completed, the problem will be solved as the number of paint layers is increased. Attempting to solve the problem by applying the paint as a thicker layer without preparing the surface will cause the paint to flow downwards and curtaining and hard to dry.
What is late drying?
Reasons due to incomplete surface preparation such as applying the paint on damp, dirty and oily surface, insufficient ventilation of the room, and insufficient mixing of the paint causes late drying of the paint. The paint will dry after a certain period, however, it may lose its gloss or dirt and dust may accumulate on top. In such cases, the paint must be sandpapered slightly and a new layer of paint must be applied. If the paint is not yet dry, the surface must be cleaned using the paint thinner and repainted.
Why do the brush marks remain visible?
Brush marks become visible on the paint if the old paint is not completely removed, the paint is not completely dispersed or the brush is pressed excessively while applying the topcoat; moreover, if hard type brush is used and the paint, previously opened and used in small amounts, is applied as dry. The surface must be repainted once the paint is dried in order to eliminate such marks.
What is paint discoloration?
Surface discolorations are seen in time due to the effects of UV beams in paints with low luminous sensitivity produced from poor quality pigments. Typically seen on exterior façades, the most efficient way to prevent this problem is to prefer ISO certified quality products like Firacolor.
How to store the paint
Paint is a material with certain useful life; undesired problems may occur in paints stored under unfavorable conditions for a long period. Such problems also cause undesired factors in the properties. Especially poorly formulated paints and not paying required attention during production become unusable in a short time. Problems such as precipitation, clabbering and separation may be seen. Ideal paint storage must be at 5-35°C temperature, protected against temperature, sparkles, fire and sunlight and well ventilated. The packaging of the paint must not be opened prior to usage, and if opened, must be used preferably. Large packages must be turned upside down every 3-4 months and primers, metallic paints with zinc or aluminum content stored for a long period must be used after mixing thoroughly with a mechanical mixer.
