Description

Acrylic sealant for installation seams “A” is used for sealing and filling exterior installation seams. It suits joints and gaps between window, balcony, facade, and stained-glass structures, as well as polyurethane foam seams in thermal insulation systems.

The material helps protect installation foam from direct environmental exposure and UV radiation, form a neat exterior seam around window and door blocks, and seal junctions and technological gaps.

The sealant has a copolymer-acrylate base, white color, and can be used outdoors within the application temperature range of -20°C ... +35°C. After formation, the layer is designed for operation in the -40°C ... +80°C range.

Before application, surfaces should be dry, strong, level, and cleaned of contaminants, deposits, and poorly bonded particles. Polyurethane foam in insulation seams and technological gaps should be neatly and evenly cut, without tears or surface defects. Droplets of moisture or frost on the surface are not allowed.

Porous or weakened surfaces should be treated with Lacrysil primer concentrate diluted 1:10 and dried. If the sealant temperature is below 18°C, keep the product for 24 hours at room conditions of +18°C ... +25°C and mix until homogeneous.

Fill the working cavity evenly with a continuous layer. Recommended seam dimensions are 3-5 mm wide and 3-3.5 mm thick, with 1-3 mm overlap onto the adjacent surface. Large cavities are filled gradually after the previous layer forms. After application, level the layer with a spatula moistened in soapy water or shape the seam as required.

Layer formation takes 24-48 hours and depends on seam size, substrate condition, and environmental conditions; under unfavorable conditions it may increase up to 6 days. Protect the finish layer from water contact for 72 hours.

Benefits

  • designed specifically for exterior installation seams;

  • helps protect polyurethane foam seams from UV radiation;

  • suitable for window, door, balcony, facade, and stained-glass structures;

  • can be applied at temperatures from -20°C to +35°C when manufacturer instructions are followed;

  • compatible with many traditional building substrates according to the table;

  • available in several pack sizes for local and larger amounts of work.

Where to use

  • exterior installation seams around window blocks;

  • door block junctions with wall structures;

  • balcony, facade, and stained-glass structures;

  • polyurethane foam seams in thermal insulation systems;

  • sealing technological gaps and joints outdoors;

  • work on concrete, brick, gypsum, plasterboard, stone, wood, tile, primed metal, plastic, and PVC according to the compatibility table.

How to choose a variant

  • 600 ml is convenient for local repair or a small number of installation seams;

  • 1.2 kg suits several window or door junctions;

  • 3 kg is useful for a series of seams on one project;

  • 7 kg is suitable for larger facade or installation work;

  • all variants are white, so check whether the color fits the visible seam line;

  • for quantity planning, use the consumption reference of 0.13 kg/linear m and the actual seam size.

How to use

  • clean surfaces from contaminants, deposits, and loose particles;

  • cut polyurethane foam in the seam evenly, without tears or surface defects;

  • do not apply the material to surfaces with droplets of moisture or frost;

  • treat porous or weakened substrates with Lacrysil primer concentrate diluted 1:10 and let them dry;

  • if the sealant temperature is below 18°C, keep the product for 24 hours at +18°C ... +25°C and mix;

  • fill the seam with a continuous layer 3-5 mm wide and 3-3.5 mm thick, level it with a spatula, and protect the finish layer from water for 72 hours.

FAQ: use, consumption, and common mistakes

  • What is it suitable for?
    Acrylic sealant for exterior installation seams in window, balcony, facade, and stained-glass structures, including UV protection of PU foam seams.

  • When is it not suitable?
    Do not apply to wet, greasy, dusty, or weak substrates; permanent water immersion requires a separate compatibility check.

  • What is the consumption or yield?
    Product specification guide: 0.13 kg/linear m. For an exact estimate, consider area, joint size, application method, and substrate condition.

  • How long does the layer dry or form?
    Product specification guide: 24 - 48 hours. Cold, humidity, or a thick layer can increase the waiting time before loading.

  • What are the common mistakes?
    Applying over an old weak layer, skipping cleaning, wrong joint geometry, and water contact before the layer forms.
