If you're a small business owner or MSME in India, or even a medium- to large-sized company looking to buy industrial and construction products online, you may have heard about welding electrodes but may not know much about them. In this guide, we will provide you with a comprehensive understanding of welding electrodes, their types, and how to choose the right one for your business.
Welding is a process that involves joining two or more materials through the application of heat, pressure, or both. One of the essential components of welding is the welding electrode, which serves as the source of the electrical current needed to create the weld. Welding electrodes come in different types, each with its own unique properties and applications. In this comprehensive guide, we will explore two main types of welding electrodes: consumable and non-consumable, and their subcategories.
What are Consumable Welding Electrodes?
Consumable welding electrodes are electrodes that melt during the welding process, and their material is deposited in the weld pool to join the workpieces. They are divided into two main categories: bare electrodes and coated electrodes.
Bare Electrodes
Bare electrodes are welding electrodes without any type of coating. They are mostly used in applications where there is no need for coated electrodes. Bare electrodes have low hydrogen levels, making them ideal for welding materials that are susceptible to hydrogen cracking. However, they are not suitable for welding in environments that have high moisture levels.
Coated Electrodes
Coated electrodes are welding electrodes that have a coating applied to them. The coating serves several purposes, including protecting the weld pool from atmospheric contamination, improving the arc stability, and reducing spatter. Coated electrodes are classified according to the coating factor, which is the ratio of the diameter of the electrode to the diameter of the core wire.

New-age waterproofing chemical formulations: All you need to know
Waterproofing chemical formulations are a solid foundation for the construction industry worldwide. Waterproofing is achieved by making the structure resistant to water and this is enabled by suitable chemical formulations for waterproofing. These chemicals are used to waterproof several parts of the buildings that are developed for both residential and commercial purposes. Before delving deeper into waterproofing chemicals, one should know that membranes and coatings are usually used for this purpose while building structures which also add to structural integrity.
Waterproofing chemicals have a major function in building construction, enabling a layer of protection, thereby ensuring a more controlled environment. This also enables restricting the penetration of water at the same time. Numerous such waterproofing chemicals include hypalon, polyvinyl chloride, EPDM, bituminous materials, and more. Damp proofing is also integrated into the waterproofing procedure at times. It is executed with grouting, liquid coatings, primers, plasters, and concrete additives. Earlier waterproofing methods like HDPE or PVC have their limitations. New-age techniques and formulations have greatly evolved towards enabling better layers of protection around structural peripheries. Here is a look at some of the top waterproofing chemical formulations available today.
Nanotechnology for waterproofing purposes
Nanotechnology has been undergoing a process of steady evolution, whereby there has been extensive research done on its integration into daily life and myriad applications. Ceramic coating is now being used for waterproofing chemical formulations. Nano coating comes with hydrophobic properties and oleo-phobic attributes as well. Hence, the surface can restrict the entry of water, dry particles, dirt, and oil. Several super-hydrophobic coatings are deployed throughout dry surfaces. The best part is that nano-coating does not lead to any colour changes on the surface after application. It remains invisible for the most part.
Crystalline waterproofing technologies
Another technology used for waterproofing chemical formulations is crystalline waterproofing. Crystalline waterproofing chemicals combat the movements of water through concrete. This is done by enabling the creation of a specific barrier for waterproofing purposes. The chemical formulation enables the reduction of the permeability of water along with the porosity of regular concrete. This enhances its overall lifespan and durability greatly. It also lowers overall maintenance costs in turn. Whenever any liquid comes into contact with any surface, then there is the formation of a contact angle between the edge of the liquid drop and the surface. This is required to be higher to make any surface super-hydrophobic or hydrophobic.
This technology has a chemical reaction with water whenever it is applied to concrete and non-hydrated particles of cement. This also form needle-shaped crystals which are insoluble, filling up micro-cracks and pores of capillaries while blocking all water and contaminant pathways at the same time. Any moisture levels seen throughout the concrete’s lifespan will naturally stimulate crystallization, leading to permanent protection through suitable waterproofing.
Waterproofing membranes
Another one of the highly advanced waterproofing chemical formulations is membranes, which come in either liquid or sheet forms. Liquid membranes are either rolled, sprayed or trowelled onto concrete surfaces, leading to the formation of a rubbery and waterproof coating. Sheet membranes have a distinct form. They remain stuck towards the concrete surface for ensuring a waterproof barrier. Hence, they restrict the penetration of water into the building’s structural elements or even other finished areas. Micro-cracks are also sealed for lowering permeability levels. This also works to safeguard the concrete against any intrusion of water, even when the hydrostatic pressure is on the higher side.
Self-healing spray-on coating which repels water
Self-healing and water-repellent coating (spray-on) is another unique technique for waterproofing surfaces. This is an innovation that is yet to grow roots around the world and the mainstream construction industry, using a material known as the fluorinated polyurethane elastomer and another F-POSS molecule that repels water. The coating can heal itself innumerable times upon damage. It can also self-heal from a chemical standpoint. This makes it one of the most unique offerings that the world has witnessed till now.

It is applied in a manner that is similar to priming and printing. It is also easy to execute at the same time. A good exterior primer is required for painting the concrete in question, while the polymer paint application happens for the top surface. Two coats have to be enough while the polymer acrylic paint is also for surface irregularities, smaller cracks, and gaps.
The elastomer is a solution that comes with elastic attributes. It can reshape itself based on the structure where it is applied. This will stay behind a waterproof and air-proof seal. This also helps in safeguarding concrete buildings for several years, irrespective of the temperature aspect. It is an excellent covering and is a lot thicker than the paint in question. It enables the creation of a flexible but thick coating which enables a waterproof exterior for the structure.
Silicone Sealant
Silicone Sealant is another waterproofing material that is worth investing in as per several experts. It helps with effective waterproofing. Silicone sealant is useful for safeguarding concrete and boosting its waterproof attributes. Silicone also works as a crack filler along with a sealant and may be applied for cracks till a quarter inch or 0.6 centimeters thin. It is a material that is used for extensive waterproofing. Polyurethane or silicone sealant will function neatly, including in the renewal of concrete structures which are already well-guarded.
Hence, silicone fillers may be used for colour corrections while renovating homes or even post-rough construction. The sealant may be applied with the help of a spraying method or extrusion may happen with the help of a regular paint roller. Silicone sealant is an ideal choice for those seeking more detailed solutions. It comes in an adhesive liquid form and usually resembles a gel. It comes with a unique chemical structure as compared to other organic and polymer-based adhesives. Unlike them, silicone retains its overall flexibility and balance at both lower and higher temperatures successfully.
Membrane Waterproofing
This is another waterproofing material that you can consider investing in. This is a concept that is deployed by several people. Membranes are some of the top materials that are used during the waterproofing procedure. This helps safeguard the concrete from adverse weather conditions and liquid membranes are neatly used for the concrete structure in question. There are flexible attributes that lead to the formation of impermeable layers upon the concrete to safeguard the interiors from any external damage. Waterproofing solutions may be chosen for foundations, basements, and sub-structures along with other suitable layers for ducts and bigger drainage pipes. Membranes are names for those structures which are permeable on a selective basis.
Crystallized Waterproofing
These sealants are also suitable waterproofing materials as per several experts. They function through a catalytic reaction which helps in concealing holes, cracks, and other irregularities within concrete. They also enable easier closing of concrete pores and capillaries while penetrating deeply into the concrete for better sealing of cracks that often happen naturally for these structures.

Waterproofing chemicals for concrete structures—What are the options available to you?
When it comes to finding the right water proofing chemical for concrete structures, here are some of the top choices that are worth considering:
Grout and Epoxy
These have to be injected into the concrete surface, especially if cracks are forming on the same. This is possible by putting chemicals into cracks or drilling surface holes for the insertion of the material. The grout will be injected by applying pressure and it reacts with the water inside for the sealant formation. This will lead to a resistant layer forming in place of the earlier crack.
Vinyl Ester Resin
This is another water proofing chemical that is quite popular for usage across concrete structures. These are coatings applied on the surfaces for resisting damage due to corrosion or acid. The resin’s chemical attributes enable waterproofing membranes that keep water damage and moisture away.
Polyurethane Liquids – These are chemical membranes that are used for open and exposed surfaces, including roofs. They are flexible although ideally suited for flatter surfaces without enhancing the concrete’s moisture levels.
Polyurea Coatings
These are excellent coatings that come with polymer-like molecular attributes. They can take care of water damage, abrasion, and other issues with their strength and anti-bacterial features.
Bituminous Methods – These coatings are suitable water proofing chemicals that are ideal for building foundations. They are also called asphalt coatings which fuse gravel or sand, with attributes depending on the grade of polymer and fibre.
Crystallization Waterproofing Solution
These solutions are tailored chemically for resisting the impact of several aspects leading to corrosion, such as NO2, CO2, and CO along with damages from water. The surface porosity is a key aspect here since the crystalline substance attributes enable filling up all the gaps in the composition of the cement for keeping water away successfully. This system may be executed via a spray or brush. The chemicals can be set deep in the concrete for long-term structural safety.
PRAS
This stands for Permeability Reducing Admixtures. They have several types and come with the same molecular or functional aspects like crystallization waterproofing. The chemicals are known for their ability to reduce the permeability levels of concrete. These PRAs also help in lowering dry shrinking while safeguarding a concrete structure against any impact due to freezing or thawing. They also reduce the impact of lower chloride ions by enhancing the strength of concrete sealings. PRAs are sometimes applied for the concrete mix available, which makes them suitable for concrete that is exposed continually to dampness, rain, and moisture.

The material is non-toxic and has diverse shades and colours, making it a great option by all means.
Conventional Waterproofing Methods for Terraces
Along with new-age waterproofing with chemical solutions, several traditional systems are still in use widely. These include the following:
Brickbat Coba System
This uses flat bricks on the roof and they are glued with cement and dried. They are then sealed with compounds along with water and cement. The mixture is spread throughout the roof, filling up all the gaps. Water is used for curing for two weeks.
Lime Terracing System
This is not a permanent waterproofing solution although it is widely used even today. At the same time, if there are surface water infections, then the whole process has to be revamped as well.
Waterproofing your roof with waterproofing chemicals—What you should also know
- You should always go for waterproofing if you have a flat and open terrace layout.
- Whenever inspecting the roof, ensure that you also look for other issues including leakages from water pipes, damp patches for the roof, lack of any outlets for water, lack of any slope, and other internal cracks. Patio and deck waterproofing may also be done whenever it is required.
- You should invest in a good chemical solution and sealant only after taking professional guidance.
- Exterior dents and cracks should be repaired immediately without any delays whatsoever.

Everything You Need to Know About Wall Putty Types
Are you planning to renovate your home or office space? If yes, wall putty is crucial to your renovation project. Wall putty is a coating material applied on walls before painting to provide a smooth and even surface. It helps hide undulations or surface imperfections, giving the walls a polished and aesthetically pleasing look.
But with so many types of wall putty available in the market, selecting the suitable one can be confusing. In this article, we, the experts at L&T SuFin, will guide you through the different types of wall putty and their uses, helping you make an informed decision.
Cement-based Wall Putty
Cement-based wall putty is a popular material used in construction and renovation projects. It is a smooth, white paste applied to walls before painting to create a flawless finish. The putty is made of cement, white powder, and additives, making it easy to apply and durable. It fills in any gaps, cracks, or imperfections on the surface, creating a smooth base for the paint. Cement-based wall putty is suitable for interior and exterior walls, especially on damp surfaces, such as bathrooms and kitchens.
Acrylic-based Wall Putty
Acrylic-based wall putty is popular for repairing and smoothening walls before painting. It is made by blending acrylic polymers with calcium carbonate, talc or quartz fillers. This putty has excellent adhesion properties, dries quickly and is easy to apply. Acrylic-based wall putty is also water-resistant, making it suitable for interior and exterior walls. Its smooth finish creates a perfect base for painting and prevents the growth of algae and fungi on walls. It is ideal for interior walls, especially on surfaces prone to cracking, such as plasterboards.
Gypsum-based Wall Putty
Gypsum-based wall putty is made by blending gypsum powder, minerals, and other additives. It provides a smooth finish and excellent adhesion to surfaces. It is ideal for interior walls, especially on surfaces prone to cracking, such as plasterboards. Gypsum-based wall putty is also fire-resistant, making it suitable for use in areas where fire safety is a concern.
Polymer-based Wall Putty
Polymer-based wall putty is a coating material for preparing and repairing walls before painting. Unlike traditional putties made of cement, sand, and water, polymer-based putties use polymers such as acrylic or vinyl acetate to improve adhesion, flexibility, and water resistance. They also offer a smooth finish, ideal for levelling and filling cracks and holes in walls. Moreover, they have a longer lifespan and are less likely to crack or shrink. Polymer-based wall putty is ideal for interior and exterior walls, especially on surfaces prone to dampness and cracking. It is also suitable for use in areas with high humidity and is resistant to fungal growth.
Ready-mix Wall Putty
Ready-mix wall putty is a pre-mixed wall putty that requires no additional mixing before application. It is made by blending white cement, minerals, and other additives. Ready-mix wall putty is easy to use and provides a smooth surface finish. It is ideal for interior walls, especially on damp surfaces like bathrooms and kitchens.
Table: Comparison of Different Types of Wall Putty
| Type | Suitable for | Properties |
| Cement-based | Interior and Exterior | Excellent adhesion, durability, and water-resistance |
| Acrylic-based | Interior | Smooth finish, excellent adhesion, and water-resistance |
| Gypsum-based | Interior | Smooth finish, excellent adhesion, and fire-resistance |
| Polymer-based | Interior and Exterior | Excellent adhesion, durability, water resistance, and resistant to fungal growth |
