Repair of damages of an inflatable rubber boat, imposition of patches on punctures, scuffs, tears and other damage to the sides and bottom of an inflatable rubber boat.

An inflatable rubber boat requires constant self-care. Only in this case will it serve for a long time. Extending the life of an inflatable rubber boat is not so difficult. Every year, before launching, a simple surface treatment of the rubber boat with glue should be carried out. The solution consists of one part of rubber adhesive No. 88 and two parts of aviation gasoline. 

Repair of damages of an inflatable rubber boat, imposition of patches on punctures, scuffs, tears and other damage to the sides and bottom of an inflatable rubber boat.

The components of such a solution must be thoroughly mixed and applied with a thin layer on the rubber surface. Thus, microcracks are closed, through which air quietly escapes, butt joints are strengthened, old rubber absorbs the amount of liquid rubber it needs and becomes elastic. Prevention of an inflatable rubber boat is advisable at least once a year..

, made of rubberized fabrics, various damage to the bottom and sides. Sometimes the place of damage is outwardly invisible, but the sides bleed air. In this case, the surfaces of the filled compartments of the boat are covered with soap foam, preferably with a sponge.

The place of air leakage is determined by the bubbling of dusty foam and is marked with a ballpoint pen so as not to look after it after removing the soapy foam. It is advisable to start the search for damage with valves. If a leak is found in one of the valves, it must be removed, cleaned, rinsed with clean water or gaskets replaced..

If water enters the cockpit of a rubber boat, and the sides do not bleed air, it means that the bottom or the junction of the bottom with the side is damaged. In this case, the place of damage is found by thorough inspection of the bottom and its connection with the sides.

Moreover, it is necessary to examine the entire plane of the bottom and the connection, since the boat can be damaged in several places, have scuffs, scuffs, and delamination of sealing tapes or press parts. Only after the entire boat has been inspected, can repair be started.

Cold and hot ways to repair damage to an inflatable rubber boat.

There are two main repair methods: cold and hot. The most common is cold, which does not require special devices and special skills and can easily be performed at ordinary temperature in both home and camping conditions..

If repairs are made at home, then the surface on which the boat is being repaired should be prepared. It should be even and clean. In the process, it is recommended to periodically wipe it with a cloth to remove traces of dried glue.

To repair damage to an inflatable rubber boat, you must have scissors, a roller and a rolling pad, sandpaper to strip the rubber layer of the fabric, a glue brush, glue and solvent. In the absence of a roller and a disc, a suitable cylindrical object can be used..

Preparation for patching punctures, teases, tears and other damage to the sides and bottom of an inflatable rubber boat.

Small punctures, teases, tears and other damage to the sides and bottom of an inflatable rubber boat are repaired by applying round or oval patches to the damaged area. If the gap is oblong, then the patch should resemble a gap in shape, but its angles must be rounded to minimize the possibility of tearing off during operation of the rubber boat. Moreover, the patch should cover the damaged area by 25-30 mm in each direction.

It is recommended to use material that is part of the ZIP, or identical to the one on which the patch is applied. If the patch is large, it is necessary to ensure that the warp and weft (longitudinal and transverse threads of the fabric base) of the boat material and patches match.

Long sections of the gap before gluing are first stitched. To improve adhesion to the glue, the surfaces to be glued are cleaned with large sandpaper, treated with a solvent (usually all gasoline, ethyl acetate or their mixtures), which cleans the surfaces of dust formed during processing, degreases them and promotes the swelling of the rubber lining.

After processing the surface is well dried. Hands should no longer be touched, and if you need to take a patch, then take it over the edge. The glue is applied to both surfaces to be glued with a thin even layer with a clean brush. Rubber glue is stored in a hermetically sealed jar. Before use, it is mixed, and if it is too thick, then diluted with a suitable solvent, otherwise the glue does not adhere well to the material and lays in a thick uneven layer.

You can use glue included in the spare parts for a rubber boat, or rubber glue based on rubber, compatible with rubber of the outer lining of rubberized fabric. Sometimes repairs are carried out with self-vulcanizing rubber glue, which is more durable than plain rubber glue. The method of application of this glue is the same as that of a simple rubber glue.

In good weather, the repair of an inflatable rubber boat should be done in the shade, since in the sun glue applied to the surfaces to be glued quickly forms a film, which worsens its adhesive ability. In adverse weather conditions, in rain or wind, the repair of an inflatable rubber boat should be carried out in a place protected from the weather, for example, in a tent, in order to protect the glued surfaces coated with glue from moisture or debris. If a speck gets on the surface of the glue, remove it with the tip of a knife or sliver.

Sticking a patch on a puncture, scuff, tear and other damage to the sides and bottom of an inflatable rubber boat.

10-15 minutes after the application of the first layer, when the glue dries, the second layer is smeared and allowed to dry so that the knife blade barely sticks. Do not breathe on the surface covered with glue in order to accelerate the evaporation of the solvent, since moisture from respiration settles on the surface and significantly impairs the bonding strength.

The fee is taken over the edges, without touching the surfaces to be glued, and applied to the damaged place exactly at the place of damage, or laying it with one edge and then sending it to the repaired place. Or by placing the middle on the damage and spreading it in both directions. A carelessly delivered patch worsens the quality of repair of an inflatable rubber boat and causes a lot of trouble, and changing its position is very difficult. If you still need to remove the patch, then make it a jerk.

The applied patch is well pressed by hand, smoothed in the direction from the middle to the edges and rolled with a roller. It is necessary to ensure that there is no air bubble under the patch, and if it appears, it is necessary to squeeze it out. Moreover, this must be done carefully so as not to stretch and wrinkle the surface. The patch is sprinkled on the outside with talcum powder to eliminate the possibility of other parts of the inflatable rubber boat sticking to it. It is recommended to repair the boat at a temperature not lower than 15 degrees.

If there is no solvent, then you can wash the damaged area and the inner layer with clean water, and then dry them thoroughly. However, in this case, the bonding strength is lower. In the absence of sandpaper, you can clean the surfaces with a knife, but do this carefully so as not to puncture the rubberized fabric and touch the textile base.

To facilitate the repair of an inflatable rubber boat, it is recommended to take several segments of the treated rubberized fabric of various shapes and sizes with you on a trip so that you can cut out a patch of the desired shape and size on the spot. These pieces of fabric should be packed in a plastic bag..

Repair of peeling of oarlocks, leer washers, valve flanges and other rubber press parts of an inflatable rubber boat.

When peeling oarlocks, leer washers, valve flanges and other rubber press parts, the inflatable rubber boat is also repaired by a cold method. Repair requiring replacement of panels, gluing partitions, closing gaps occurring across two or more compartments, or stratification of joints, is associated with the need to send an inflatable rubber boat to specialized workshops.

Since such repairs can only be carried out using self-vulcanizing adhesives and special equipment. It is not recommended to make it for the owner of an inflatable rubber boat.

Hot repair of an inflatable rubber boat.

Hot repair of an inflatable rubber boat is mainly used in case of leakage at the place of joining of the sides and gluing partitions, when peeling, shifting or creasing on the tape (regulator) of the sides. Such repairs are carried out mainly in special workshops equipped with appropriate equipment, and at manufacturers with the ability to select adhesives and unvulcanized rubber plates from rubberized boat fabrics compatible with rubbers.

For example, the elimination of leaks of the boat “Dive” at the point of docking sides hot way is as follows. The docking unit is delaminated with gasoline and a metal ruler, cleaned of sealant.

Cut the docking tape at a distance of 10-15 mm from the edge of the regulator, cut out the regulator, grind the delaminated surfaces and rinse with their benzine. Then it is twice smeared with glue, allowing each layer to dry. Alternately assemble the docking station with the imposition of an unvulcanized regulator and sealant.

A patch of unvulcanized fabric 50 mm wide is applied to the incision site of the docking tape. An unvulcanized plate with a thickness of 0.4 mm is applied to the seizures of the lining rubber. The assembled unit is carefully rolled up with a metal roller. On the borders of the repaired section of the side of the inflatable rubber boat in order to obtain a smooth surface, sections of cellophane or lavsan film are applied.

Then, a sponge rubber board is placed on the bottom of the repair area, a metal plate and a heating plate are placed on top, then all this is fixed with clamps and vulcanization is performed in the following mode: the temperature of the tile is 135-145 degrees, the time is 30 minutes.

At the end of the vulcanization process, the tile is turned off and allowed to cool to a temperature of 80-90 degrees. After that, the clamps loosen and remove the tile. Tests of the boat after repair are made no earlier than 4 hours later. It is obvious that at home it is quite difficult to collect the necessary materials for such repair of an inflatable rubber boat.

Temporary repair of an inflatable rubber boat using special aerosols based on synthetic rubber.

It seems interesting to carry out temporary repairs of inflatable boats with the help of special aerosols based on synthetic rubber, which can seal the damaged shell from the inside. To do this, it is enough to attach a spray can with a chemical vulcanizer to the boat valve and let a spray of aerosol go there. After a couple of minutes, the aerosol will self-vulcanize and seal the boat for a while.
