General information about the material

Fiberglass putty is a two-component composition made of modified unsaturated polyester resin reinforced with special fibers. Since polyester resin is fairly solid in its natural state, several specific additives are added to it to increase its plasticity and elasticity. The putty’s composition includes fiberglass, which is intended to even strengthen the material after it dries.

The composition of the putty

Polyester resin, a viscous substance with a slight resemblance to honey, is the primary active ingredient in putty. She gives the combined mixture its strength and serves as a connecting element. Additionally, the composition contains fiberglass filler and reinforcement particles. After drying, they make the coating harder so that there is less shrinkage and less chance of cracks.

The types of fiberglass threads vary based on the production technology used.

1. Long. They are created in the process of a continuous production cycle, when molten glass turns into thin streams and is wound on the drum. After hardening, the fibers pass through a special installation, where they are covered with emulsion from starch, gelatin and plasticizers.
2. Short. It is obtained as a result of inflating liquid glass with steam or air. Ready -made fibers have a small length and resemble wool.

Usually, short reinforcing fibers are used in the putty-making process. Additionally, the material’s composition must contain styroll, which improves elasticity. A hardener is sold separately; after combining with the base, this liquid material causes a chemical reaction known as polymerization, which hardens the putty.

Properties

Fiberglass putty is perfect for aligning different flaws like chips, cracks, and pits. It can be used on both small and large products, with the latter requiring the use of a sprayer for application. There are specific kinds of car backpacks made of plastic that have fibers that serve as reinforcement; these have the best adhesion possible.

The following are reinforced putty’s primary characteristics:

• resistance to vibration;
• high strength;
• durability;
• short curing time;
• elasticity, the possibility of stretching;
• inappropriateness of mechanical damage;
• the possibility of use on any solid grounds.

Characteristics

The ideal temperature for work is +20 degrees, while +10 to +25 degrees is the recommended range for putty with fiberglass. The precise duration for drying will depend on the layer’s thickness, but it typically takes between 30 and 120 minutes. By raising the air temperature to +60 degrees, you can shorten the drying process. The putty layer should not be larger than 5-8 mm at its largest.

The scope of putty

The material is typically used to repair small to medium-sized flaws, such as microscols and scratches. Certain methods are appropriate even for the placement of large holes and through-holes in the metal and plastic details. Putty is perfect for working with aluminum and all varieties of steel, including alloyed, galvanized, and so on. It works just as well for processing items made of fiberglass, polyester laminate, and outdated primer coatings and paint jobs. The material is utilized in construction when working with:

• concrete and cement;
• wood;
• natural stone;
• artificial stone.

Paint is applied to polyester putty after it has dried to further protect its surface. Applying auto-spaces to thermoplastic and visceto-elastic (unsteady) materials, as well as base coated in etching and acid-elaborate soils, is not advised.

Advantages and disadvantages

There are many unquestionable benefits to the putty made of polyester resin and fiberglass reinforcement:

• the possibility of applying with a rather thick layer;
• lack of shrinkage after drying even with thick -layer application;
• lack of cracking during operation;
• strength, the ability to use to close up complex injuries;
• resistance to fluctuations, surfaces vibration, which only increases popularity among craftsmen;
• quick hardening, initial setting in 20-30 minutes;
• the possibility of grinding on the first day;
• resistance to atmospheric factors;
• moisture resistance, lack of damage at temperature changes, ultraviolet radiation.

One of the drawbacks of autoshpaklevka is that it is toxic due to the presence of styrene, a solvent that is extremely harmful to human health. The product must be worked with very quickly—within five to eight minutes—else it will become viscous and become difficult to level.

It is common for beginners to struggle with applying composition quickly, so they will need to practice beforehand on the draft surface. To achieve the desired shape, experience is also required, particularly when dealing with through holes and chips with intricate configurations.

The cost of putty

Putty packaging weighing between 250 and 500 g can cost as much as 350–750 rubles, depending on the product’s quality and the manufacturer’s brand. These compositions are very popular in the market despite their high cost.

A sturdy and smooth surface for refinishing is provided by car fiberglass putty with polyester resin, an indispensable material for auto body repairs. This putty fills in dents and imperfections in the car’s bodywork by using polyester resin and fiberglass strands to form a strong, flexible bond. It’s simple to use, sands down easily, and offers a strong base for additional painting and finishing. The advantages, how-to, and advice for getting the most out of fiberglass putty for your auto repair projects are all covered in this article.

Tools and materials for work

Make sure all required equipment and supplies are available before breeding the mixture.

• a set of spatulas made of metal, rubber, plastic (it will be more convenient to choose the right case in each case);
• sandpaper with grain size 60-240;
• rags or sponges;
• bar for fixing sandpaper;
• solvent for degreasing the base;
• special spray or powder composition for the manifestation of defects;
• soil suitable for the material of the base;
• tanker.

When selecting a spatula, keep in mind that the instrument with the metal canvas is better suited for handling relatively even surfaces with minor depth flaws.

The majority of the time, round, curved areas and angles are processed using rubber and plastic spatulas. Purchasing high-quality tools is advised because low-quality ones frequently have zabrines and leave micro-sparanes and break easily.

Preparatory stage

Although clean metal is the ideal surface to apply the material to, you can work even on old paint or varnish if necessary. Use a metal spatula or power tools to remove flaking, refluxing coatings. Rust-affected plots are completely removed from the foci by passing them through sandpaper. Slightly enlarged narrow cracks make it easier to use putty to seal them. Following the work surface, the subsequent actions are completed:

• processed with sand for the purpose of matting;
• cleaned of dust with compressed air, wiped with a solvent;
• They give a completely dry.

Preparation of the composition

Make sure the main component is well mixed and familiarize yourself with the manufacturer’s recommended mixing proportions before attaching the base to the hardener. Conventional electronic scales can be used for measurement; however, it is crucial that their error rate be kept to a minimum. The portion size should be such that it is finished in a matter of minutes.

Following the connection of the two parts, the putty is thoroughly mixed until it achieves a homogenous, consistent density and shade. Putty will freeze unevenly if the solution is not properly measured or if there are too few or too many hardeners. Furthermore, the substance can totally exfoliate from the substrate.

Application of putty

Working with fiberglass-based compositions requires priming the surface, puttying it, and finally grinding the coating.

Padding

Primarily high-porous concrete and wood surfaces primed. Metal does not need to be covered in dirt.

Putty

Using a spatula, the completed mixture is applied and quickly leveled in an effort to create as smooth a surface as possible. Parallel to this, the layer’s thickness was just right—not too thin, but not too thin to be allowed. They apply the second layer of the product only if necessary after waiting for the putty to fully solidify. Use the powder for defect manifestation if needed.

Grinding

This step is necessary for the coating to align perfectly and to get rid of any imperfections, no matter how tiny. They use larger-grained sandpaper to first go over the putty layer, and then they treat it with finer-grained paper (like P120). The thumbled product is then primed after the dust has been brushed off it. After that, the part can be painted right away or a layer of finish putty can be applied.
