Masonry Waterproofing Cream

Microshield Ultra is a water based masonry waterproofing cream designed to impart long-lasting and reliable water repellence combined with a strong beading effect to mineral substances such as brickwork and façades.

Microshield Ultra provides comprehensive protection for brickwork and façade against efflorescence and destruction by water soluble pollutants as well as against frost damage and the attack of micro organisms.

Furthermore, surfaces treated with Microshield Ultra can also benefit from improved thermal performance thus reducing heat loss through “wet” walls, improving the indoor environment and saving valuable energy and money.

Microshield Ultra is a creamy impregnating agent based on silanes and siloxanes. Microshield Ultra protects the material while preserving the water vapour permeability, without affecting the material surface optically. Water simply beads and runs off, and the material can maintain its natural moisture balance. The remarkable penetration of Microshield Ultra into the substrate guarantees exceptionally long-lasting and reliable protection from penetrating damp. 

Microshield Ultra is suitable for use on most kinds of mineral substances for example:

  • Bricks and clinker
  • Natural stone
  • Mortars
  • Render
  • Porous concrete
  • Concrete
  • Limestone

Beading Effect

Substrates treated with Microshield Ultra will exhibit a strong beading effect which develops within 7-10 days of treatment. The beading effect will last between 2-3 years depending on the substrate condition and exposure to weather conditions.

Excellent results

Extremely happy with the results on a problamatic damp wall, easy to apply by roller on the brickwork and brush on the joints. Its been on a good month now and the water just beads off the wall and the internal plaster has fully dried out. Best price I could find and turned up as expected next day. I hope it lasts the full 25 years!

Hi Robert Thank you for the feed back, we how have 20 Litre buckets available for larger applications. We hope this helps. The Permagard Team

Easy to use

Have used other materials of a similar type, but have to say that this applies much easier, and after 24hrs walls are slightly darker than when started, but still penetrating. Beading effect is great, and on my exposed walls should give good protection. As I had totally re-pointed my bungalow,decided that I would complete the weatherproofing by applying this. Easy DIY job, for anyone thinking about this.

Very pleased

just wanted to say thank you to Gregg for the advice to use this product, it has stopped the penetrating damp from the heavy rain we had at the beginning of the year and the internal surface are now dry. Thank you J

very good results

Having used this product over a year ago I have decided to write a review as Permagard have managed to solve my problem. We have a solid stone gable end wall that is exposed to a lot of wind driven rain which is constantly damp. Over the years we have had companies come out to supposedly fix this problem. One installed a new damp proof course which of course did not work another used Thompsons water seal to treat the wall which lasted about 6 months then I decided to contact Permagard. They immediately diagnosed the issue and suggested this product, although hesitant due to the cost I bit the bullet and purchased 6 x 5 litres. I paid a local builder to apply the product over the whole gable end. The product takes a while to penetrate and start to work, probably a bit longer than the data sheet suggests but I guess site conditions are different to laboratory conditions. Over the next few months the wall dried out completely and the damp patches are gone. Not only this but since the application in September 2012 the beading has got stronger, the wall has never been so dry/ warm and I am extremely thankful to Permagard for helping to fix my on going problem.

Very Impressed

very impressed with the beading effect of the product, the wall has dried out and despite the bad weather we have had its still dry and the surface feels warmer. The test will be over the next few years.

Can Microshield Ultra Masonry Protection Cream be applied to a painted surface?

The Microshield Ultra cannot be applied to a painted surface. The paint will act as a barrier to the deeply penetrating cream hence the cream must be applied directly to the untreated substrate. The Microshield Ultra can be overcoated with paint once the product has cured after 28 days.
