Bituminous roofing sealant
The basis of this sealant is a modified bitumen. It has an aluminum shade due to the presence of aluminum pigment.
Properties of bitumen sealant
It is produced in the form of paste and has a number of positive qualities:
- grasps quickly;
- adhesion almost with all materials;
- forms a solid, elastic surface;
- protects from corrosion metal structures;
- not destroyed under the influence of sunlight and high humidity;
- used immediately. Preparation and drying of the surface is not required.
Negative moments
It has bitumen sealant and some restrictions in application:
- does not tolerate very high temperatures;
- absorbed into porous materials, so a pre-primer needs;
- long dries if you put a thick layer. The consumption of bitumen sealant depends on the thickness of the layer;
- poor sticks to the grinding surface. It is necessary to apply soil before sealing;
- does not hold on its surface varnishes and paints;
- toxic, therefore used bitumen sealant for outdoor work.
Usage
When repairing roofs, bituminous sealant is irreplaceable when:
- Seal joints between sheets of roofing material.
- Perform waterproofing after installation on the roof of pipes, endands, various slats, in places of docking roofs and walls.
- Eliminate leaks.
- Sealing the roof in those places where the fasteners of snow-setting fixtures, stairs, railings, etc. passes through it.
Although a bitumen sealant for a metal roof is intended, use it for other purposes:
- close up of cracks in the stone before covering it with rolled waterproofing;
- they stick to them waterproofing sheets;
- covered products from concrete before laying them into the ground;
- eliminate flowing in sewage pipes, where the fluid moves in gravity.
A brief overview of popular bitumen sealants
Buy bituminous sealants is easy, but it is better to choose a better quality, having good characteristics and released by a reliable manufacturer.
Professionals often use black bituminous sealant Penosil Bitum Sealant, which is produced in Estonia. It finds use when you need to perform the following work:
- fill the seams and cracks on sedentary sites;
- eliminate the flow on a flat roof;
- seams in a metal roof;
- make more dense joints between plates or stripes from bitumen.
Specifications:
- perfectly connected with metal, ceramics, concrete, bitumen;
- melts at 100 s;
- the cartridge with a sealant is equipped with a pistol.
The sealant bituminous "moment" is produced in Germany and is no less popular. Repair them:
- roofing;
- drain pipes;
- ventilation systems.
It has high moisture, wear and heat resistance.
Good reviews deserved and Belgian single-component sealant roofing Soudal. Perfectly copes:
- with spars and cracks on the roof;
- with a sticking cold way of rubberoid;
- with repair of grooves and drainage pipes;
- with the filling of seams of sedentary.
Bituminous polymer sealant
Bituminous polymer sealant use when:
- Sealing deformation seams on the asphalt concrete and concrete coating of the automotive route or the take-off strip.
- Close up the cracks of coatings from concrete or asphalt.
Composition
The composition of this sealant of hot use includes:
- oil bitumen;
- modified rubber synthetic;
- technological additives.
Properties
The use of the sealant of bitumen-polymer in the most responsible places is due to its properties, namely:
- A large range of temperatures in which it is possible to use it. Stored at temperatures from -20 to +30 C. Operating temperature from 160 to 190 C. softened at a temperature of 95 to 105 C.
- High elasticity. Under the influence of ultraviolet rays, its properties vary only by 15% for 1000 hours.
- No shrinkage.
In various climatic zones, it is recommended to use one of 3 modifications:
- BP-G25;
- BP-G35;
- BP-G50.
The sealant of bituminous polymer "prestige" is worthy of the sealant, which produces the Russian company Polymer Progress. This material:
- one-component - black mass;
- wear-resistant. Withstands both significant fluctuations in temperature and aggressive medium;
- well grip with metal, stone, concrete.
The composition includes:
- polymers;
- petroleum road bitumens;
- plasticizers;
- adhesion additives.
Apply it when repairing roads and airfields.
The universal bitumen-polymeric sealant of hot use of TechnoNIKOL No. 42 from the domestic producer "TechnoNIKOL" is widely known.
- all characteristics appear after 1 hour after applying;
- applied at different temperatures, which is a big advantage.
In the above examples, it was about bitumen-polymer sealants of hot applying, but there is another kind of cold applying. This refers to the sealant-mastic BIOM and. Releases material "Antihydron". Applied at:
- sealing of seams both horizontal and vertical;
- sealing small cracks;
- independent waterproofing coating device;
- stacking Ruberoid.
It is a sticky paste, a very viscous, reinforced fiber polymer.
Bitumen rubber sealant
The main difference between bitumen-rubber sealants from simply bituminous is that:
- Its foundation is bitum and rubber.
- Its vibration-fixing properties are preserved even at very low temperatures - maximum -60 C.
- It is more economical.
- It does not require constant heating. Therefore, electricity saves and disappears the need for special equipment.
- On the rubber-bitumen sealant the price is significantly less than, for example, on bitumen-polymer.
Best bitumen rubber sealants
A good option is the Bitumen-rubber sealant "TYTAN" from Tytan. It has a number of advantages:
- good grip with dry and wet materials;
- resistance to different atmospheric influences;
- the ability to hold on vertical surfaces due to high viscosity;
- plasticity constant;
- the absence of asbestos.
They repair roofs:
- metal;
- bituminous;
- tiled;
- wooden.
Seal:
- cracks;
- seams;
- leaks.
Compacted:
- drains;
- downtown windows.
High quality is the sealant bitumen-rubber Bitum 300, which has proven itself when repairing and sealing the roof, because:
- retains its characteristic in the range -35 + 110 s;
- applied at a temperature not lower than +5 and not higher than +30 s;
- dries in 20 minutes;
- it is consumed 25 ml / on m. with seam parameters 0.5x0.5 cm;
- it is stored for 1 year.
Now summarize how nevertheless choose a bitumen sealant. Tips simple:
- first, give an estimate of the surface to be sealing;
- secondly, read the instruction that is on the package;
- thirdly, decide on the amount;
- fourth, demand from the seller a certificate for the selected material;
- fifth, while working with sealant, follow the instructions.
