The thick white cream formulation is easy to use and ready straight out of the tub. Apply by brush, roller or airless spray. Watch as it cures to a colourless finish, letting the natural look of your home shine through. Prevent penetrating damp while allowing saturated walls to dry out faster than on untreated brick. The water-repellent finish discourages mould and algae growth.

To protect your external walls from algae and mould

I have used this product and found it exactly as described,it was easy to apply and dried quickly,just waiting to see when we have some rain if it works as well as they say it should.
Application was simple. A little goes a long way and it covers well. I found a fluffy roller was more effective than a brush. Time will tell if it keeps rain out of the bricks. Fingers crossed 🤞 t
Was advised to use this product. Easy to apply, now it's wait and see
Used this recently on the outside wall which takes most of the rain and bad weather. It took longer than I expected for the stonework to return to its original colour So far all seems well and the water is starting to bead off the wall when it rains
Good guilty product, do what it say on the tin
Easy to apply, only time will tell how well it performs.
Great it is a cream! But! It takes a lot of working to make it cover and you use a lot! Not sure if it will actually work?
Expensive but effective
Great product worked really well
Brilliant. Works a treat
It does what is says on the container!
Saves time and money when using instead of cavity trays to brick walls. BCO happy for this to be used.

Can I apply Stormdry Masonry Protection Cream onto Lime Mortar?
Yes, as long as there is some sand content within the lime mortar mix.
We recommend waiting 1 to 2 months before applying Stormdry Masonry Protection Cream onto recently applied lime mortar. Earlier application may inhibit the mortar curing process as well as Stormdry Masonry Protection Cream penetration.
If there is cement in the mortar mix, Stormdry Masonry Cream can be applied after 2 to 3 weeks.
Will an application of Stormdry Masonry Protection Cream alter the aesthetics of masonry by drying with a sheen (a shiny finish) or change the appearance of the masonry in any way?
Stormdry Masonry Protection Cream has been formulated to cure to a colourless finish with no gloss or pigmentation.
Because Stormdry Masonry Protection Cream achieves its water repellency by lining the pores of the masonry rather than by coating the masonry surface, it will not leave a glossy sheen associated with some masonry sealant products.
In some rare cases, after an initial application of Stormdry Masonry Protection Cream, there can be a slight darkening of the brickwork, but this will fade with time and will return to normal.
We always recommend carrying out a small discrete test area prior to the full application of Stormdry Masonry Protection Cream to masonry to confirm aesthetic acceptability.
How long does the beading effect take to appear once Stormdry Masonry Protection Cream has been applied?
It may take up to two months after application for the full beading effect to appear when rainfall hits the treated wall.
Can I apply Stormdry Masonry Protection Cream to a wet wall?
Stormdry can be applied to damp / wet walls, although it will slow down the absorption time. It will not affect the performance once Stormdry Masonry Cream has 'soaked in'.
Can I repoint a wall that has been treated with Stormdry Masonry Protection Cream?
Once a wall has been treated with Stormdry Masonry Cream, new mortar will struggle to adhere to it unless the following steps are carried out:
Rake the existing mortar out to at least 25 mm to remove any existing mortar that has absorbed Stormdry Masonry Cream. Repoint with a sand:cement mortar containing Stormdry Repointing Additive No.1.
The above also applies to lime mortar.

It is always recommended to apply Stormdry Masonry Cream to a small area to check compatibility before applying it over a wide area.
Can I apply a second coat of Stormdry Masonry Protection Cream after an initial coat has been applied?
A second coat is not necessary, assuming it was applied in accordance with our preparation and application guidelines and to a compatible substrate.
We do not recommend applying more than one coat as this may reduce wall breathability.
Can I apply Stormdry Masonry Protection Cream to internal walls?
Stormdry Masonry Cream is designed to prevent rain penetration through an external wall, whilst allowing water vapour from within the building to pass through to the outside.
For this reason, we do not recommend it for use internally.
