Before spraying, the dust on the surface of various painted panels and furniture should be removed. Shake the BioNatro® spray well, and spray in a uniform horizontal line (one word per line) about 30-45CM away from the spraying surface. The moving speed is slightly faster, and the effect is not ideal if the distance is too far or too close. (Note, do not spray too much to avoid dripping). About 30 minutes after spraying, it will be effective after natural air drying. The drying time varies with the weather and environment. Try to keep the home ventilated, and the best effect will be achieved after 72 hours. If the smell of formaldehyde is strong, repeat spraying on the same position at intervals of 2-3 days can achieve a solid effect.
