Beyond spalled brickwork and efflorescence for walls

BEYOND SPALLED BRICKWORK AND EFFLORESCENCE FOR WHEN YOU PROTECT AND RESTORE WALLS…

With modern cleaning, coating and sealing technology, it’s easier than ever to arrest the deterioration of masonry and roofing materials as well as regenerating and improving the appearance of tired old materials such as brick…

Unless you want to repeat the hard work here then are seven tips to help you get the most out of products that use the latest nanotechnology to protect and regenerate buildings like your client’s:

1. Know your material capabilities

Some surface treatments just seal, while others improve the thermal properties of a wall or roof (up to 58% better in some cases) for a warmer, cosier, more environmentally friendly structure. Similarly, did you know that at just 4% moisture content, the thermal performance of a wall is reduced by 50%! (Source: isopaint.Com). And the lesson? Know what you want to achieve and have confidence that a suitable new-generation product is out there.

2. Preparation matters

If there’s one message you should get from the manufacturers of cleaners, coatings and seals that use nanotechnology, it’s that preparation always rewards the contractor and their customer. Thorough preparation is essential, even for the most advanced products such as iso hydroblock wb liquid. A little extra effort before application helps to get the best out of such products, achieves a more rewarding result and delivers a happier customer who will be more willing to recommend you.

3. Go colourless

Why? Because a colourless surface treatment wont obliterate the underlying masonry and allows the treated surface material to show off its natural beauty. What’s more, some products even actively rebuild the natural colour of the substrate.

4. Choose a reputable material source

Generally, you get what you pay for. You may pay a little more, but the performance benefits and peace of mind for you and your customer will be worth it. Take advantage of the latest high-technology water-based proofing products. Not only do they protect against salt blooming and brick efflorescence, but they inhibit colour degradation and accumulation of dirt on the surface of the masonry – so the finished structure looks better for longer.

5. Make sure the surface to be coated is dry

It’s a minor detail but an important one; always follow the manufacturer’s instructions, but as a guide, the moisture content of the substrate should be below 45% (measured by a pinless moisture meter such as the etma dt-128m).

6. Deal with any surface soiling

If the surface to be treated is soiled or discoloured, maybe by moss or algae, always use a suitable biocidal cleaner-disinfectant such as iso a-clean. Afterwards, one coat of sealer may be sufficient, but if a second is needed, always apply it within one hour of the first application. And don’t get the sealer on glass.

7. Remember the test coat

By the way, always apply a test coat for everyone’s peace of mind before committing to coat the complete structure.

You may be a confident diyer, or the most experienced building professional, but your hard-won skills and experience could be undermined unless you choose materials wisely and apply them correctly.

It’s not hard to shortlist the most experienced specialist material manufacturers, the ones who’ve invested in the latest nanotechnologies so you can deliver a great job, with no costly call-backs and a delighted customer who will sing your praises for years.
