Home Care

Regarding protection of the roof from India's extreme heat and rain in the monsoon season, a specific PU roof coat usually outperforms the typical exterior emulsion as the former creates an effective membrane while the latter is a purely aesthetic element applied to the surface of the roof. Macaw Home Care PU Coat is an easy-to-apply one-component waterproofing liquid paint created especially for coating the roof and walls, producing an effective, highly flexible membrane, resistant to ultraviolet rays and capable of bridging the cracks that occur. The flexibility property is especially important in relation to roofs because they tend to expand and contract due to daily temperature changes more significantly than vertical walls, and a non-flexible membrane will eventually crack. Provided the PU coat is applied properly, i.e., primed and covered by the necessary number of undiluted waterproof layers, its performance will be much more effective than any other paint film could ever be on the roof.

PU coating on a roof refers to a polyurethane-based liquid waterproofing membrane applied directly onto the roof surface, forming a continuous, flexible, protective layer once it's cured properly. Macaw Home Care PU Coat works this way, a one-component product creating a heat-resistant, highly elastic membrane over the roof that actively prevents water seepage while bridging small cracks that would otherwise let moisture through underneath. Unlike standard paint, this polyurethane paint for walls and roofs stays flexible even as the surface expands and contracts with temperature changes throughout the day, which matters considerably for a horizontal surface facing direct sun and pooling rainwater. It's typically applied as a diluted priming coat first, followed by two undiluted waterproofing coats with adequate drying time between them. This layered application is really what gives PU roof coating its long-term reliability against leaks.

Yes, polyurethane paint of this waterproofing type is versatile enough for both interior and exterior wall applications, though it's most commonly chosen for exterior surfaces and roofs facing direct weather exposure rather than sheltered indoor walls. Macaw Home Care PU Coat can be diluted and used as a primer on both porous and non-porous surfaces, then applied as a waterproof topcoat suited to vertical walls as well as horizontal roof surfaces. Its highly elastic, crack-bridging nature makes it particularly useful on exterior walls prone to hairline cracking from structural movement or temperature swings, while its adhesion means it works across a range of substrates. For interior use, it's less commonly needed unless the wall faces persistent dampness or seepage, since interior spaces don't really face the same weather exposure that makes waterproofing polyurethane paint essential outdoors.

The most effective waterproofing of exterior walls is one that not only ensures high resistance but is also flexible because otherwise, due to the expansion and contraction of the wall itself, the coating will simply crack, which will undermine the goal of waterproofing itself. All of these characteristics are provided by Macaw Home Care PU Coat due to its elasticity and ability to bridge gaps thanks to the polyurethane coating, which creates a waterproofing of exterior walls membrane, while providing resistance to UV exposure as well. Appropriate preparation of the surface is also very important because the walls need to be cleaned, cracks should be filled, and primer needs to be applied diluted in order for the undiluted waterproofing material to be applied on top of it.

When it comes to waterproofing exterior walls, the use of PU-based paint that is able to bridge hairline cracks will provide more effective protection compared to using normal waterproof emulsion paint only. Macaw Home Care PU Coat is used precisely for this reason, because it forms an elastic and UV-resistant membrane which actively closes cracks. This is important for exterior walls which undergo constant expansion and contraction due to changes in temperature. Indeed, a rigid membrane would be prone to cracking in such a case, thus allowing the passage of moisture inside again. The application of such paint requires dilution of the coat when applying it as a primer coat, and then applying undiluted waterproofing coats with enough drying intervals between them. It is only in such a way that the resulting membrane gains its properties.
