Outdoor spaces – Revive And Seal Your Concrete


 

Spring is here and summer is just around the corner! With the longer days and the chill of winter long gone, a lot of people get into the spring-cleaning mood. It’s almost like it is part of a yearly ritual, rooted in tradition. The sense of satisfaction and accomplishment in getting the place spruced up for the summer season is a big drive for many people.

 

Cleaning and sealing tips for concrete

One effective way to keep your concrete driveway, walkway, walls, pool deck, patio, courtyard and alfresco entertaining area looking great and inviting, is to give the concrete a good clean by removing any debris, stains, weeds, algae and other organic growth – and seal it.

Even though concrete is a tough and durable product, it is still subject to wear and tear from natural elements and general daily use. When sealed, your concrete will be protected from liquid sinking into the pores of the concrete. It provides a durable chemical protection that reduces the chance of concrete staining and keeps it looking clean and new for longer. Sealing the concrete will not only protect your concrete from water penetration, stains and prolong its service life, but it will also make the subsequent cleaning of your concrete a lot easier.

 

How to clean concrete without a pressure washer

Stains can easily embed into the pores of unsealed concrete and can be difficult to remove. Cleaning concrete with a pressure washer is effective, but if you do not have one, take a look at our tips on how to effectively give your concrete a thorough clean.

 

Three main points:

  1. Choose the right cleaning agent
  2. Use the right type of brush/broom
  3. Rinse well with a garden hose

 

Choosing the right cleaning agent.

The key is to determine what kind of stains and dirt you have on your concrete to find what type of cleaner that is best suited for removing those.

 

  1. PH Neutral. It is a mild cleaner that is ideal for indoor or lightly dirty exterior concrete.
  2. Acidic. It is generally used for removing rust stains, dirt, and efflorescence on concrete. It is often used for the preparation of the concrete surface before installing a sealer.
  3. Alkaline. This is used as a degreaser to remove oil stains, so it is effective in cleaning up garage floors and driveways where cars often are parked.
  4. Enzymatic/bacterial concrete cleaners are effective in cleaning organic matter such as mould and protein stains. This cleaner helps kill bacteria and lift those stains.

 

Once you have chosen a suitable cleaner, follow the manufacturer’s instructions carefully and always check the safety data sheets to ensure that you take the appropriate safety measures.

If there are areas such as wood, glass, metal and plants that you do not want the cleaning agent to be in contact with, be sure to cover those areas. Once prepared, apply the cleaning solution.

The cleaning agent can be applied by using a low-pressure spray pump. Work the cleaner into the concrete by brushing the concrete with a deck brush* (no metal bristles) that is designed for the type of chemical you are cleaning with so that the bristles do not disintegrate.

Follow the manufacturer’s instructions of how long to let the cleaning product sit on the concrete before and after using the brush.

If the chemical is to sit undisturbed on the concrete before using the brush, consider misting it with water rather than spraying it with a hose to keep the cleaning agent from drying while you wait.

Once you have finished scrubbing the concrete with the deck brush, generously rinse the concrete with a garden hose and make sure that the cleaning agent is washed off completely. If the stains and dirt are not quite removed, repeat the process and/or use a pressure washer.

 

* If cleaning with a brush, make sure not to use a metal bristle brush because small parts of the metal bristle may break off and embed into the concrete, which likely will lead to rust stains.

 

Penetrating water repellent sealers for concrete and masonry protection

 

Sealers are essential for building protection and are used for a wide variety of purposes. The biggest benefit of having the concrete sealed is that the concrete is protected from water absorption, thus helping extend its lifespan. Besides keeping the concrete dry, it also helps keep dirt particles, oils, food and drink spills from penetrating into the pores of the concrete. In that way it is much easier to clean.

There is a vast collection of different types of concrete sealers and each has their own individual properties. The most commonly used are film-forming sealers (e.g. acrylic, epoxy and polyurethane sealers) and penetrating sealers.

Penetrating sealers are not coatings, whereas film-forming sealers are. Film-forming sealers create a physical protective barrier that sits on top of the surface as a coating and stops the penetration of moisture.

Penetrating water repellent (PWR) sealers, on the other hand, penetrates into the pores of the substrate where it chemically reacts below the surface from within the pores and forms a durable chemical barrier underneath the surface. A penetrating water repellent (PWR) provides an effective protection of the concrete and masonry without altering the visual appearance and it cures with a dry look finish.

 

Waterstop Solutions PWR 180+

We employ the latest waterproofing technology in a range of systems applicable to porous substrates, such as concrete, brickwork, mortar or stone.

Waterstop Solutions PWR 180+ (Penetrating Water Repellent) is a low viscosity, silane-siloxane system that can be applied on new and old, cleaned concrete and masonry. The sealer penetrates deep into the porous substrate, creating a bonded hydrophobic lining to the pores.

By creating a bonded hydrophobic lining to the pores, the penetrating water repellent (PWR) makes concrete and masonry less porous. This means that the treated surface will repel water and resist staining from leaves, oil leaks and grease as well as protecting against waterborne salts. It also does an excellent job of resisting mould, mildew, and fungus. (Please note that a spill that is left to sit, can eventually stain the surface.)

This treatment significantly reduces the absorption of water and waterborne salts while also being “breathable”, which means that it allows moisture to migrate through the surface as a vapour. This is a very important feature. Waterstop Solutions PWR can also be used as a chemical damp-proof course (DPC). It prevents rising damp through capillary action in masonry, brickwork and stonework structures.

The solution does not produce any discolouration of the substrate. It has a dry-look finish and has excellent resistance to weathering.

It is easy to apply and very effective without altering the look of the concrete.

 

Common areas where Penetrating Water Repellent (PWR) sealer is used:

 

  1. Concrete
  2. Brickwork, masonry blocks
  3. Tiles and grout
  4. Pool surrounds
  5. Some natural stones
  6. Traditional and modern stucco and render
  7. Paths and traffic bearing surfaces

 

Key benefits of Waterstop Solutions PWR 180+

 

  • Provides an invisible water repellent surface. Maintains the texture and colour of the surface treated. Invisible, dry and natural look finish.
  • Allows the passage of water vapour.
  • Excellent water repellent of concrete, concrete blocks, brickwork, pavers, tiles, tile grout and some natural stones.
  • Long-lasting barrier against efflorescence and surface salts, moisture and chemical attacks.
  • Prevention of dirt retention and deep stains.
  • Reduces cleaning costs. No more scrubbing or power washing. The PWR sealant decreases dirt adhesion and prevents moss and mould growth. (Rainfall or a light garden hose wash is enough.)
  • Reduction of sandstone decay due to attack by salts and low pH precipitation.
  • Elimination of white salt spotting on brickwork.
  • Treatment of rising and salt damp.
  • Acts as a replacement of damp-proof course (DPC).
  • Helps maintain a great curb appeal and sale value with a new-look preservation.

 

We have a wide range of sealers, membranes and coating products we can recommend to meet your different requirements and expectations. There are many considerations to take into account when choosing the right coating for a project. Our experienced team is happy to help you with identifying and selecting the protective coating, membrane or penetrative sealer to suit the requirements of your project.

Waterstop Solutions penetrating sealant  treatments

We employ the latest waterproofing technology in a range of systems applicable to porous substrates, such as concrete, brickwork, mortar or stone.

Depending upon your application, one of these systems may be a more economical option with the added benefits of introducing minimal change to the surface appearance of the original substrate and requiring very low to zero maintenance.

One such water-based treatment is our Hardener Densifier. The hardener densifier treatment reacts with moisture and the free lime or calcium in concrete to permanently improve concrete abrasion resistance, reduce dusting and porosity for easier maintenance, help heal minor static cracks, thus greatly extending the life of ageing substrates.

 

Suitable for a wide range of applications such as:

  • New and remedial waterproofing
  • Dust proofing
  • Reducing mould and dirt build-up
  • Reducing cleaning costs and slip hazards
