1. How to apply Chukum?
Mix it with Chukum water and the base of Chukum (a mixture of powder and cement), apply it on the surface in patching or flattened rustic finish form (preferable of powder and mixture to obtain different finishes) creating spaces with natural and unique ambient. The mixture is mainly applied in walls, pools, landings and floors.
Instructions for use:
Pour a sack in a clean bucket and the Chukum base; mix it with Chukum water to get the recommended consistency to apply it as putty. It is applied on full walls and it polished with preferably round trowel. It is like applying a polished cement wall, only that the tone color is cream and reflects when drying, moisture that leaves a marbled appearance. When burnishing, Chukum water or natural water can be used so that the trowel can lift and give more color. It is important that there is sufficient moisture in the wall prior to the application and it is required that it can be cured with water the following days.
Steps:
1. Prepare the area where the mixture is going to be applied.
2. Cure the walls with sufficient water during an adequate period of time before its application.
3. To avoid setbacks, prepare the necessary buckets of putties.
4. Apply on full walls.
5. Check the wall periodically, avoiding cracking by covering it with material prior to drying.
6. Accompany the drying of the wall with a constant burnishing (polishing).
7. The next days CURE with water to avoid cracking.
8. Anticipate the application to inclement weather.
Warnings:
- In case of eye contact, wash with plenty of water.
- Storage bags in a place free of moisture.
- Do not swallow, if swallowed go to the doctor immediately.
2. Can it be used on drywall (Sheetrock® )?
Yes, along it is applied with a cement base paste and Chukum water, although it requires an acrylic varnish later. These materials have their own care, ask the precise specification to the manufacturer to avoid future damage.
3. Can it be applied on cement board (Durock®)?
We recommend giving a prevously finish with basecoat or rustic ready-mix and it can be used with both, cement base paste and our Chukum base.
4. Can it be applied with colors?
Actually Chukum gives a particular color, but can be applied with other natural pigments or dyes (the detail is to manage the mixture combination to reach the desired color).
5. Why on some walls are produced dark patches?
These are given by the reflection of moisture in the previous finish, 99% in Chukum cases reflects the wall imperfections: if there were repairs, if one part dried before the rest, if it retained humidity. However, these imperfections can be avoided and corrected by checking the finish before performing the task.
6. Why does Chukum crack?
It can occur for several reasons attributable in 70% to the application and 30% to the previous material.
Possible causes:
- Not clean well the surface where it is going to be applied.
- Not moisten the application area enough to maintain a slow drying during burnishing.
- Not reinforce the application with an additive.
- Apply moisture-repellent materials in the area prior receiving Chukum, which do not allow a combination between new and old cements (check the composition of some mortars that usually place before the Chukum).
- Apply Chukum immediately or 24 hours before receiving the revoke.
- Apply Chukum in areas that feel hollow, which warns that the patch was misplaced and is going to come off.
- Apply on fresh patching walls (This will make evident marks on the wall after the application of Chukum).
- Not cure the spaces where the Chukum coating was applied 24 hours after the application and for at least 7 days.
- Exposure to the sun the applied surface in at least 7 days later without the curing treatment.
