Purpose and top 4 types of waterproof paints, advantages and disadvantages of use
Thoughts on which wall covering to choose are visited by everyone who plans to renovate the premises. The number of finishing materials is growing every year, and the choice of manufacturers is expanding. Satisfied with the variety of shades and textures. The ideal option is to use a waterproof alkyd paint, and a water-based texture is suitable for interior decoration.
Purpose of waterproof coloring compositions
Moisture-resistant paint is intended for painting plastered concrete or brick surfaces, walls or wooden elements. It is used for both interior and exterior work. Dries quickly. Sometimes it takes longer when interacting with metal.
Review of popular varieties
The classification of waterproof paints is focused on the composition of the dye, the degree of resistance to moisture. Experts recommend choosing a suitable option based on these criteria. This is the only way to understand what will suit the needs of the user. For example, for rooms with high humidity (bathroom, basement), it is recommended to opt for an alkyd component.
Alkyd enamels
Paint of this format is an ideal choice for rooms where high humidity is constantly observed, and it becomes necessary to create an additional layer of waterproofing.We are talking about a bathroom, basements.
Alkyd enamel contains special chemical components that increase hydrophobic functions. After complete drying, a special film forms on the surface. It gives the painted surface a brilliant shine, prevents the ingress of water particles.
Benefits :
- fast drying;
- operating temperature range (from -60 to +60 degrees);
- variety of shades;
- resistance to ultraviolet radiation;
- rich color.
Disadvantages of alkyd enamels:
- low durability of the coating;
- level of toxicity;
- low thickness of the coating layer.
water-based
Water-based paint is most often used for interior decoration of living rooms and the ceiling. It is distinguished by weak waterproofing functions, although it is considered water-repellent, therefore it cannot be used in rooms with high humidity.
The slight moisture resistance of the pigment is due to the texture. Once dry, a porous structure is formed.
Over time, moisture enters the pores, which, accumulating, leads to the destruction of the colored layer.
Advantages of use:
- does not have an unpleasant odor;
- due to the porous structure, the surface has access to oxygen;
- when dry, forms a flat matte surface;
- protects against fungus and mold.
Disadvantages of a water base:
- low performance settings;
- not suitable for painting metal elements;
- does not lie on surfaces painted with linseed enamels and varnishes;
- cannot be used in sub-zero temperatures.
Acrylic
Among all types of waterproof paints, the acrylic composition is characterized by an average level of moisture protection.This allows it to be used in rooms with intermittent high levels of humidity. At the same time, being subjected to prolonged exposure to water, the painted surface loses its aesthetic appeal, harmful mold and fungal formations begin to multiply on it.
The advantages of acrylic enamel:
- high drying speed (up to 2 hours);
- profitability due to even distribution over the surface;
- ease of use;
- high level of fire safety due to special flame retardant additives;
- resistance to external influences (ultraviolet light, sudden temperature drops, etc.);
- large color palette;
- the ability to effectively mask the slightest surface imperfections.
Disadvantages:
- difficulties in choosing a color (in finished paintings from different batches, the shade may have some differences);
- low level of protection against fungal activity and mold;
- a high level of toxicity of the individual components of the coloring composition.
Silicone Pigment Dyes
Modern silicone-based paint appeared relatively recently, but has already won the trust of many consumers. It combines the best properties of acrylic, alkyd and aqueous formulations.
Silicone paint is characterized by high water-repellent properties and good air permeability. The coating has an elastic structure, therefore it is able to recover over time with minor mechanical damage.
Paint is characterized by its ability to effectively resist negative external factors.She is not afraid of a sharp change in temperature, prolonged exposure to ultraviolet rays. Breakthrough can be safely washed using chemical reagents without fear of loss of performance and visual appeal.
Benefits :
- wide color palette, large selection of shades;
- UV resistance;
- high level of protection against fungal activity;
- immunity to temperature extremes;
- no unpleasant smell, low toxicity.
Defaults:
- high price range;
- inability to use on metal surfaces;
- Silicone colorant can only be applied to a carefully prepared and cleaned surface.
Advantages and disadvantages
Moisture-protective dyes have advantages and disadvantages. Before buying, consumers should familiarize themselves with the peculiarities of using paints. Benefits of waterproof formulations include:
- The painted surface is characterized by excellent decorative and protective functions. Due to the peculiarities of their texture, such paints dry quickly, forming a durable coating with a long service life.
- The presented type of paint is ideal for rooms with a constantly high level of humidity.
- The protective function of paint prolongs the performance of plaster, wooden planks and plasterboard.
Besides the positive aspects, waterproof paints have a number of disadvantages:
- Before the staining procedure, it is necessary to thoroughly clean the surface of irregularities, accumulations of dirt and dust. Otherwise, the coating will peel off and deteriorate quickly.
- The decorative layer has no protection against mechanical damage (except silicone compounds). At the slightest impact, defects appear on the surface.
- Most waterproof paints do not have a sufficient level of vapor permeability and water resistance. Due to this, excess moisture accumulates in the room, which can worsen microclimatic indicators, negatively affect the decorative functions of the coating.
Despite its drawbacks, waterproof paint is the best choice for interior decoration.It surpasses conventional dyes, provides reliable protection of premises from excess moisture.
