How to waterproof your terrace step by step in an easy way

If you have a terrace, you know that it is one of the spaces most exposed to the elements. Rain, sun and sudden changes in temperature end up affecting the materials, causing leaks, cracks and damp. That is why, waterproofing the terrace is not just a question of aesthetics, but a necessity to extend its useful life and protect the rest of the house. Fortunately, today there are solutions that facilitate this work without the need for complicated processes. One of them is the Imper Antigoteras by Tecno Prodista high quality elastic waterproofing that, when properly applied, provides a durable barrier against water and wear and tear.

Why it is important to waterproof the terrace

Over time, terrace materials suffer from micro-cracks due to natural expansion and contraction caused by temperature. These small cracks are enough for rainwater to seep in, causing damp spots, mould and even structural damage. In addition, an unprotected surface absorbs more heat in summer, which increases the temperature inside the home and can affect energy efficiency. Proper waterproofing avoids these problems, keeping the terrace in good condition and offering greater comfort at any time of the year.

Imper Antigoteras: the solution from Tecno Prodist

The Imper Antigoteras is a rubber-based coating that stands out for its elasticity, excellent adhesion and weather resistance. Thanks to its formulation, it adapts perfectly to the natural movements of the surface without cracking. This means that even after years of exposure to heavy rain, UV rays or temperature changes, its properties remain intact. In addition, it adheres without problems on materials as varied as cement, concrete, porous tiles or brick, NOT on ceramic substrates, which makes it a versatile option for different types of terraces.

Unlike other waterproofing products, this product forms a continuous seamless layer with a satin finish that does not become sticky. It is easy to apply and can be applied by brush, roller or spray, allowing anyone, even inexperienced, to achieve a professional result.

Surface preparation

Before applying the waterproofing, it is essential that the surface is completely clean and dry. This involves removing dust, grease and loose debris, either by sweeping, brushing or washing. If the terrace has visible cracks, it is advisable to repair them with polyurethane mastic. MASITEC FLEX W by Tecno Prodist To guarantee a uniform seal, special attention must be paid to the joint between the wall and the floor and the drains, if there are cracks of more than 2 mm they must be sealed beforehand. This prior step is key for the product to adhere correctly and fulfil its protective function for a longer period of time.

Step-by-step implementation

The process for waterproofing the terrace with Imper Antigoteras is very simple. First, apply a diluted layer with 10% of water, covering the entire surface homogeneously and in one direction only (horizontal or vertical). It is important not to leave any areas uncovered, as any gap could become a leakage point. Also apply to the skirting board or baseboard that borders the terrace, as if you were making a glass. Once the first coat has been applied, it should be left to dry for three to four hours. Afterwards, apply a second coat, this time undiluted, to reinforce the protection in the opposite direction to that used in the first coat. On terraces with significant leaks, it is recommended to apply a third coat. Although it dries to the touch in approximately one hour, it is recommended to wait at least 24 hours before exposing the terrace to normal use or rain.

Tips for a perfect finish

For best results and proper grip, work should ideally be done on a dry day, with no rain forecast, and at moderate temperatures, preferably between 10 °C and 30 °C. Gloves should be worn to avoid direct contact with the skin. If the deck is large, working in zones can help you maintain a steady pace and ensure that the coating is uniform.
