High Performance, Long Life Roof Waterproofing Paint

There are many areas of many buildings that require waterproof protection. From the obvious roofs and the gutters and down pipes, down to the external walls that will need protection from the elements. Basements and balconies would also need water proofing protection especially where water that rests after a heavy rainfall can very slowly impregnate itself into the underlying substrate and the rooms beneath.

Balconies and steps leading to basements are generally coated with ashfelt which has for a long time been a very good water proofing material, but it doesn't tend to maintain its flexibility, or its water proofing benefits for long periods of time. For these types of applications we would be looking to use Sikafloor 400 N as an excellent, flexible, waterproofing UV stable, and hard wearing coating. It can also be used on balconies, and terraces.

When we are waterproofing roofs, we would be looking at various different substrates. Again, from asphalt, to 3 layer felt, and also concrete which has long just been left bare on many flat roofs. In these instances, we would be looking for water protection to come from liquid applied coatings. These are seamless and very easy and quick to apply without the use of any hot works, which lends itself very well for the application in areas where gas torches and burners cannot be used for safety reasons.

A very good system that is predominantly used to achieve 20 to 25 year water protection for roofs, would be the 3M Scotchkote Poly-Tech 661 Stroke, 662 system. This again, is a very fast drying low odor material that is liquid applied with the use of the Scotchkote reinforcing mesh material.

Benefits of Waterproof Roof Paints for Flat Roofs

Using and applying waterproof roof paints to your flat roof is essential in prolonging the life span of your flat roof. As well as providing a waterproof coating to the roof, they also help to protect against other elements such as weather, mould and cracks. The waterproof roof paints that we supply are all created for the highest quality finish possible and can be applied in a range of conditions such as hot weather, cold weather and wet or dry conditions. Applying these roof paints to your flat roof can also be extended to get the best value for money from your products by coating guttering, balconies, metal, wood, corrugated materials and more, to help seal the areas around the flat roof to create a more stable level of protection.

How to Apply Waterproof Roof Paint to a Flat Roof

Applying your waterproof roof paint to a flat roof is a fairly straightforward process that requires little work but an attention to detail. Firstly, it is essential to clear the area of debris and apply a roof cleaner to ensure any grime and grease is removed. We would then recommend applying a roof primer to prepare the surface for any roof paints or coatings. 

Once the primer is applied and dry in an even, thin layer, you can then move on to applying the waterproof paint to the roof. You may need two coats of the waterproof roof paint to ensure sufficient coverage and protection for your flat roof. Again, we recommend applying these coats in thin and even layers for the best quality finish. Once applied, wait for the coating to fully dry. The products that you use will detail on the packaging the ideal weather conditions for the best finish.
